1:13start off the powershell team about 12
1:15years ago maybe a little bit more um and
1:19that worked out pretty well because
1:20after having shipped a couple versions
1:22they
1:22made me a distinguished engineer and
1:24then the lead architect for
1:26windows server 2012. awesome
1:29that worked out pretty well so now i'm
1:30the lead architect for windows server
1:33and system center data center products
1:34so
1:36having some fun oh boy having a lot of
1:38fun and with powershell and what we're
1:40going to talk about the windows
1:40management framework
1:41all of this bundled together not just in
1:44server 2012 but it works
1:45all the way backwards to 2003 so that we
1:48can
1:49we can do all of this management with
1:50everything that we have in our
1:51environment not just necessarily the
1:53latest and greatest that's the plan
1:55back to filling up your arsenal i like
1:57that term i like that term too
1:58that's turning out pretty good so let me
2:00tell you a little bit about myself
2:02i'm jason helmick i work with
2:04concentrated technologies i
2:06do this for a living i love to train i
2:07do powershell and i also work as an
2:09engineer and a consultant
2:11mainly doing a lot of automation with it
2:13uh author of a new book that's coming
2:15out
2:16learn windows iis in a month of lunch is
2:20tough title to say uh and it's not only
2:23about learning iis but it's
2:25using powershell for it so yeah just
2:27some uh interesting little tidbits about
2:29me
2:30truly what the best thing to know about
2:31me is i get to sit next to him
2:34so as we do this so this is gonna be a
2:36lot of fun
2:37let's start off with um showing you what
2:39we're gonna talk about today
2:41so as you can see from the agenda we're
2:43gonna cover several topics today and
2:44it's actually quite a few of them
2:46i'm gonna start off with one of my
2:47favorite ones which is don't fear the
2:49show you know i think a lot of
2:51it guys when they first get started with
2:53this i hear this all the time
2:55they they're scared to get started with
2:58powershell they're not used to a command
2:59line they don't say they're scared
3:01but they're not used to using a command
3:03line deep down
3:04they see that console window and they
3:06just like i don't know what to do yeah
3:08so one of the first
3:09headlights yeah so one of the first
3:10things we're going to want to do is
3:12get rid of some of that fear show you
3:14how straightforward you can get started
3:15with powershell
3:17and then we're going to take you into
3:19what powershell starts to look like
3:20and of course we're going to talk about
3:22the reasons why powershell even exists
3:23and there's some
3:25incredibly important ones so we'll also
3:27get into the help system probably one of
3:29the most important things that we do
3:30today
3:31the pipeline and extending the shell all
3:33of this stuff that we're going to do is
3:34going to make more sense as we hit it
3:36looking at what objects are
3:37and drilling into the pipeline what is
3:39that weird character i keep seeing
3:41between these commands and we'll get
3:44into one of the most important
3:45advantages that you have
3:46which will be uh powershell remoting
3:49which will let you do
3:50a lot of your stuff in scale that's
3:52where it gets fun that's where it really
3:53gets fun
3:54by the way so people should be uh doing
3:56these exercises with us so
3:58you know you should be at your computer
4:00fire up a powershell window and uh type
4:02along with us
4:03that's the way you get the most out of
4:05this course and actually i think that's
4:06the best way to get the most out of this
4:08is i i know you want to kick back and
4:10kind of you know
4:10sip some coffee or whatever and listen
4:12to us but keep your fingers close to
4:13that keyboard on that console
4:15um and powershell so you can work with
4:17us on this and you should be joining are
4:18you gonna tell them about the
4:19q a yeah yeah a matter of fact i got a
4:22slide coming up oh
4:23here let's do the expectations things on
4:25our target audience and then we'll
4:26talk about how to join us um the this
4:29was designed
4:30for it pros however if you're dev uh
4:33please join us on this this was designed
4:36for it pros
4:37to be a quick deep dive and get started
4:39with powershell there are so many
4:41guys out there right now and gals that
4:43are trying to get started with
4:44powershell
4:45and sometimes you find it really
4:47difficult well this is the ideas to get
4:48you through the difficulty and we're not
4:50just doing an introductory level we're
4:51going to go in pretty deep with using
4:53powershell
4:54and it doesn't matter what product you
4:56want to use it with whether you want to
4:57use it with active directory or
4:58sharepoint
4:59you got to know the tool and if you know
5:00the tool then the products are
5:02easy to deal with so if you're an it pro
5:05if you work in help desk if you're a
5:07developer interested in what powershell
5:09can do for you
5:10this is the place to be and as a couple

6:54so look we're going to go through an
6:55overview of what powershell is white
6:56even exists and of course this is the
6:58great time for jeffrey to
7:00to help us out understand why we even
7:01have this and then we're going to start
7:02going into
7:04how to take some of the fear out of
7:05running powershell we'll show you how to
7:07get it installed and how to get it set
7:08up
7:09so let's rock and roll first of all the
7:11purpose of
7:12and i just want to point out can you see
7:13the slide yeah yeah look at you guys you
7:16see the you
7:16and the them that that picture you
7:18that's that's a picture of me when i was
7:20younger
7:21uh-huh i swear to no it's not really a
7:23picture in me so here's the idea
7:25you're sitting there struggling with the
7:27day-to-day events of everything that's
7:29around
7:30you you've got projects that you have to
7:32have done there are things that are on
7:33fire
7:34and everything's going right and you
7:35have them you have your your end users
7:37your boss
7:38all of these people that are that are we
7:40need this now we need this now
7:42and in microsoft environments this has
7:44been a challenge we've had some tools
7:47and you've had some scripting languages
7:49and we had vb
7:50script but there were certain
7:51limitations that would
7:53challenge us and it wasn't quite
7:56complete enough
7:57was also kind of hard and doing
8:00automation and solving problems
8:01was a huge challenge then came along
8:06this product that you made so why is it
8:09that
8:10what is it that you were trying to solve
8:11for all of us guys in i.t
8:13yeah you know when i came to the company
8:14i uh i said well you know we need an
8:16automation strategy and they said well
8:18we have an automation strategy i said
8:20really where and they said well you know
8:23here and it was vbscript it's like uh no
8:26my friends that's not an automation
8:27strategy
8:28and they said well here you know we've
8:29got these great apis like no my friend
8:32that's not
8:32automation i don't like the sound of
8:34that exactly
8:36and so what i knew was that we needed to
8:39have an interactive shell
8:41an environment that someone would say
8:42hey go explore the system try this try
8:45that try that
8:46be able to get things done and then from
8:48there the idea is like hey
8:50i i notice i do type the things over and
8:53over and over again
8:54why don't i put it in a script and just
8:56run it from there
8:58and then say well you know that's great
9:00now it's you know
9:01reduced my repetitive strain injury and
9:04i'd like to parameterize it oh i'd like
9:06to parameterize it now i can
9:08use it for a wider range of things and
9:09now i'd like to share it with you
9:11and now we'd like to use it to manage
9:13thousands of machines
9:14so we had this model we called it the
9:16develop or the admin development model
9:19which really you know bruce payet
9:20superstar bruce he says
9:22uh the the average lifetime of a command
9:25line script
9:26or sort of a script um starts at the
9:28prompt and
9:29ends at the the carriage return that it
9:31was very important that it be an
9:32interactive environment so that you can
9:34explore and honestly have fun
9:36i mean if there's two things you get out
9:38of today's session one
9:39is a spirit of exploration hey this is a
9:42great environment to go explore explore
9:44explore
9:45and then two just how much fun it is i
9:47mean it's just a blast to be able to
9:49to use and then from there to be able to
9:52automate
9:52you know automate automate automate you
9:54know if we had just transformed
9:56you know a click click click experience
9:58to a click click experience
10:00like okay that's good like lots of
10:02people prefer this
10:03over over this but you really
10:06wouldn't have transformed the platform
10:09it's the ability to then do this this
10:11and this and then say
10:12save right and then just say click
10:16and run and i and i i just want to
10:17emphasize that
10:19we're unaccustomed in windows
10:21environments of having an
10:22interactive shell a real time solve your
10:25problem tool i mean we've always had
10:27basic commands but that really wasn't
10:29solving our problem
10:30this means solve your problem and then
10:33literally
10:34copy paste or hit save and now you can
10:37automate it
10:38and it doesn't require any more than
10:41have fun
10:42finding and solving the problem and now
10:44i'm on my way
10:45yeah you know i mean you might say well
10:47why do i need to do that
10:49and the answer is because everybody's
10:50scenario's different
10:52so we were talking in the car last night
10:54about how well hey in
10:55exchange you know the gui you know
10:58honestly we spent a lot of time talking
10:59to customers and trying to understand
11:01the scenarios and put that into the gui
11:03so that you just click click click
11:04but the reality is and jason was telling
11:06me the story about hey
11:07i did that but then what i needed to do
11:09was i needed to have different quotas
11:11for these
11:11types of users versus those types of
11:13users versus those types of users
11:15and uh and and the gui didn't help me
11:18you know i had to go
11:19do a ton of clicking so we might have
11:21gone and said oh well okay we'll add
11:23that to the gui
11:24but then all of a sudden if you try and
11:25deal with everybody's scenarios in the
11:27gui
11:27it becomes big and it becomes complex
11:29and it becomes hideous
11:30and then you can't use the gui and i
11:33think that that's one of the uh
11:35biggest issues that people will will
11:37start to see at first is that
11:39the graphical there's nothing wrong with
11:41using a graphical interface
11:42i mean sometimes i use it too i and i
11:44use it for things that i just need to do
11:46once one off once every blue moon you
11:49know creating a site link in active
11:51directory
11:52the graphical is great for that but when
11:53you have business challenges that can't
11:55be met
11:56such as and i think what we were talking
11:57about last night was i needed to set the
12:00mailbox limits of
12:01a particular ou in active directory well
12:04the graphical doesn't support that and i
12:05don't expect microsoft to solve that
12:07problem for me because
12:09how are they supposed to know what my
12:10issues are powershell is the way that
12:13you can solve those issues and that you
12:15can
12:15get these business problems solved and
12:17it doesn't take six months you get them
12:19solved right now
12:20and then you automate them so the
12:22purpose to powershell really is all
12:23about
12:24making you more effective getting stuff
12:26done faster
12:27and solving problems that you probably
12:30had a hard time solving before
12:32so because often they're unique yeah
12:34very unique
12:35so let's see here installing powershell
12:38now
12:38right now there's there's a lot of it's
12:40kind of confusing for a lot of folks
12:43first of all let's talk about some of
12:44the versions of powershell nobody should
12:45have v1
12:46right now right can we you should
12:48upgrade
12:49you've got to release okay so v2 um
12:53came out a couple of years ago right
12:55yeah a couple years ago
12:56and you should have v2 on windows 7 and
12:59you should have it on 2000 a 2008 r2
13:02um and v2 also works and is is part of
13:05the update stream that you can uh
13:07update for windows xp and shame on you
13:09if you still have windows xp
13:10and of course server 2003
13:13now v3 is the new one and v3 came out
13:17for windows 8
13:18and for server 2012. if at all possible
13:22as the administrator
13:24you want v3 on your box and you're going
13:26to see plenty of examples of that today
13:27oh yeah of needing to have v3
13:30you can upgrade v3 um and have that on
13:32your box for both
13:34the uh uh uh windows 7 and
13:38server 2008 r2 and that's it though
13:40right windows server 2008
13:422008 2008 r2 and 2008 r2 i got to make
13:45sure i get all them all in there
13:47so you can upgrade to v3 now you don't
13:49have to rush right out right now and
13:50start upgrading your servers
13:52to v3 and you should take some cautions
13:55out there there are some products that
13:56aren't quite ready to handle v3 and
13:58there's plenty of information on that so
14:00don't be that guy or gal that makes that
14:02mistake and accidentally upgrade a
14:04server
14:05to v3 if the product running on it is
14:07not ready for it but on your
14:09administrative machine
14:10you got to have v3 you're going to love
14:12the features we show you today with it
14:13yeah you should always read the release
14:14notes you know we tell you what what it
14:16works with
14:17if you have this don't install that yeah
14:19release notes are really good along with
14:22you know testing is also really good um
14:24as well
14:25um if you take a look at the slide real
14:26quick you'll see that there's a place
14:28where you can download it's a strange
14:29name to download uh powershell three
14:31it's called the windows management
14:32framework
14:33we're gonna talk a lot more about what
14:34the what the term the windows management
14:36framework means it's not just powershell
14:38and there's a link there for you so that
14:40you can get it downloaded now if today
14:42you have v2 on your laptop you'll be
14:44fine
14:44but probably during lunch you're going
14:46to want to use v3
14:48and just to let you guys know so that we
14:49can get the confusion out of the way
14:51what we're doing today
14:52is how to use powershell what we show
14:54you how to use today
14:55is going to work on v2 v3
14:59and that mythical thing that's coming
15:00out sometime in the future
15:02v4 ish like stuff so you're
15:05going to be just fine with without
15:08whatever version you have that's we're
15:10going to be using
15:10it's all going to be about the tool
15:12today so
15:14well let's talk about launching
15:15powershell how do you find powershell to
15:17launch it and guys i'm actually going to
15:19demonstrate this off of my box real
15:20quick
15:22one of the most interesting things here
15:24is if you're on windows 8
15:26you have this magnificent windows key
15:28that brings up
15:29your desktop for you and to find
15:31powershell it's actually very simple
15:33just start
15:34typing the word powershell
15:37now i have to tell you the first thing
15:39that i always do is right click and pin
15:41this
15:42to my taskbar i need to you'll have this
15:45you're going to have
15:46powershell open more than anything else
15:49that you work with so
15:50you want to make sure you right click
15:51and get this guy pinned i've already got
15:53mine penned
15:54down here on my desktop so that you can
15:57see it now if you're working with
15:59um a pre windows 8
16:03operating system you're going to have to
16:05click on the start menu and i've got a
16:07screenshot of what that looks like here
16:09in the slides
16:11you'll click on the start menu as soon
16:12as i can figure out how to bring the
16:13slide back
16:14up it's this guy over here you're going
16:16to go under accessories and then
16:17windows powershell will be at the bottom
16:20and you're going to notice that there
16:21are two kinds of them out here you're
16:22going to see some repeats x86 versus
16:25ones that aren't x86
16:27the x86 are obviously the 32-bit
16:29versions you don't want to run those you
16:30want to run the
16:3164-bit version on your 64-bit os
16:35and we'll talk a little bit later about
16:36the ise but this is a great scripting
16:38editor
16:38that we can use as well so as long as
16:42you got powershell ready to go
16:43then we're ready to start to work with
16:45it rock and roll baby
16:47now let's talk a second about comfort
16:51comfort is important like these chairs
16:53right here
16:54in this studio are very very comfortable
16:56and that's very nice
16:58we're going to spend a lot of time and
16:59i'm rocking back and forth because
17:01they're so comfortable
17:01swaying swaying we're going to spend a
17:04lot of time
17:06looking at this console yep and
17:08powershell uses
17:10does he use every possible character on
17:12the keyboard
17:13no actually there's the up arrow
17:16great it's the up arrow that we don't
17:20use
17:20oh that's awesome well guys this is what
17:22i'm talking about
17:24first of all let me launch powershell
17:25and show this to you now i'm going to
17:27launch it i'm logged in as a regular
17:28user account
17:30and i want you to notice when i launch
17:31powershell the first thing you take a
17:32look at the top of the screen here see
17:33how it says windows powershell
17:35if you want to do some administration
17:36that's not what you want it to say so
17:38let me close this and show you
17:40if you're in as a regular user account
17:41you want to right click and do run as
17:43administrator if you're an administrator
17:44it'll already launch it
17:46with administrator if not it'll prompt
17:48you for credentials so that you can
17:50have administrative access we're going
17:52to talk about security later but this is
17:53actually an important thing
17:55notice as i'm looking at the console
17:57right now
17:58this is something that we're going to be
18:00staring at for a long time
18:02so there's a couple of things that you
18:03definitely want to be able to tell the
18:04difference in
18:06by the way one of the tricks there is if
18:08um if you're trying to do something
18:10and it's not working like this morning
18:12or trying to set some things up
18:14and i did get vm and it there was it
18:17showed me nothing
18:18i was like oh do i have the wrong
18:20machine did i provision this i recently
18:22provisioned it did i
18:23like forget to set things up and then i
18:25looked and i saw that i wasn't in
18:26admin mode so then you bring it up in
18:29admin mode and i said get vm and you see
18:31all your vms
18:32so if something's going a little wonky
18:33go check and uh
18:35see that you are running his admin and i
18:37just have to say that we're gonna be
18:38doing
18:39several things today and out of those
18:40things that we're doing today
18:42if you're not in administrative mode it
18:44isn't going to work it's going to be
18:46very wonky you're going to get error
18:47messages
18:48access denied messages and so you want
18:51to make sure you're in as administrator
18:52mode
18:53take a look at the characters i have on
18:55the screen can you see the difference
18:57on your screen with those characters you
18:59zoom it
19:00well no i i want them to look at it and
19:02go i can't tell the difference
19:03oh i want them to go no i don't know
19:05what it is don't you zoom it yeah don't
19:07use it with that
19:07um this is important you need to make
19:10sure that this screen
19:11you can see these individual characters
19:13i've got a grave character or a backtick
19:16character
19:17and then a single quote and there's only
19:18a couple of pixels in difference
19:20so here's actually one of the most
19:22important things to do when you're
19:23getting ready to use
19:24powershell i'm going to go in here to
19:26the properties and we're going to adjust
19:27this console
19:28now i'm not going to change mine because
19:30that'll screw all the views up but let
19:32me kind of show you the idea here
19:34under fonts you want to use a font that
19:37is
19:38nice and bold and thick and they gave
19:40you one called lucida console did
19:42i did i say that right you see concert i
19:45i have no idea
19:46consoles lucida
19:49nevermind that's okay consoles is a nice
19:52font but it's thinner i prefer the
19:54heavier weight font
19:55and then you want to adjust the font
19:56size but when you do that
19:59to get it to a nice font size you're
20:00going to notice in this preview pane
20:02that the pretty powershell window is
20:04going to extend to the right
20:05and go to the bottom and these are all
20:07bad things and let me tell you why
20:09when powershell is giving you
20:10information it wants to
20:12sometimes put information all the way to
20:14the right and all the way at the bottom
20:16and so if your screen has extended
20:19beyond the boundaries of your desktop
20:21you're not going to see anything so and
20:24you don't want scroll bars all over the
20:26place so let me show you how to fix that
20:28oh you don't use bold i always use bold
20:30do you use bold always
20:32really yeah that scares me oh because it
20:34feels like it's yelling at me or
20:36something
20:37okay well you want to turn the bullet on
20:40i always do
20:40okay let's turn bold on i find well
20:42here's the deal when you present
20:44if any of you ever present to the the
20:46audience always use bold
20:48because then it's just easier to read
20:50like a couple hundred females
20:52i don't want to turn it on now okay okay
20:55now in layout guys layout is where
20:57you're going to adjust
20:58your screen width and so that it fits
21:02and then what you want to do is fit just
21:03like this in the preview window
21:05let me show you two things the window
21:06size for width is right here and that'll
21:08adjust its width and i'll screw mine up
21:10for a second
21:12and see how it's kind of going off to
21:13the the right over there
21:15you don't want that you want your width
21:16so that it fits so you don't have a
21:18horizontal i think that's this way
21:19horizontal
21:20scroll bar when you adjust the window
21:24width size you also want to make sure
21:25that you keep the buffer size you don't
21:27want things going off into the buffer
21:28where you'll never be able to see it
21:30height is an important one as well i
21:32want you to notice as i scroll up and
21:33down this height
21:35what i don't want to do is scroll that
21:37all the way below my desktop because
21:39then when you see data
21:40data will get put down at the very
21:42bottom and you won't see it so i want it
21:44to fit on my desktop
21:45a vertical scroll bar you'll have will
21:47be okay
21:48make sure that for the height buffer
21:50size you get at least three
21:523000 or greater and i want to warn you
21:54that when you're working with some
21:55products that have a powershell console
21:57that console is set to 300 by default so
22:00you definitely want to change that
22:02you're going to lose information and not
22:03be able to scroll back and see it
22:05when it comes to colors oh dude
22:08i'm not changing the colors because i
22:10like the color scheme you picked out
22:12i mean you could i mean but you know if
22:14you want to change the colors to
22:15something that you like to read
22:17you know you want to make it green
22:18screen or whatever or
22:20come up with some weird color
22:22combination knock yourself out but i'm
22:24going to leave it at the default color
22:25size the important thing is good
22:27yeah i know i thought the yellow would
22:28look great the important thing is
22:30is that your console is now ready to go
22:33and it's all set up and it's in a
22:35comfortable font so while we move on
22:37take a second and make sure that you've
22:39got a nice looking powershell
22:41console to take a look at so let's see
22:44what we're doing next here i think we're
22:45ready to kind of
22:47get into some demonstration stuff
22:50yeah yeah this is lucky lucky lucky
22:55oh man that's old and you get like this
22:57milk mustache going i just like this is
22:59great get powershell this is awesome
23:01so let's talk a little bit um and start
23:04off by taking some of the fear out of
23:06powershell before we talk about this
23:08this magic word commandlet um
23:12you needed to come up with your own
23:15commands
23:16not the windows native ones you needed
23:17your own commands
23:19why the term commandlet yeah so there's
23:22two answers to that
23:23so first is that uh powershell um
23:27we want to have a model of composition
23:30okay and so the model of composition if
23:32you actually take a look at it
23:34the commands that you write are really
23:36really really small
23:37and the idea is that then you leverage
23:40the engine to do common processing
23:43so if you had each one of the
23:45commandlets try and do big tasks by
23:48themselves
23:48i want to get things and i want to
23:50process things and i want to format them
23:52then every developer would be doing
23:53things differently right you know
23:55oh well i like the term sort and you
23:58like the term order and order by and all
24:00that and so
24:01so he said no no you write the things
24:03that you
24:04and only you can use do and then
24:07leverage the engine to do everything
24:09else okay and so these commands got
24:12really really small and that was the
24:13whole point they're really really small
24:16and you use the pipeline to do bigger
24:18tasks
24:19and because of that you get or you get a
24:22a
24:22regularity that is to say you're going
24:24to learn something and then you can use
24:26it over
24:26and over and over again so that's where
24:28the term commandlet came from
24:30but then when we went to bring it out
24:32the documentation people said
24:34no way you can't do that we don't make
24:36up terms
24:37it's called command that's like well no
24:40we're going to call it command line
24:41and they just went to the mall it's like
24:42no no no no i said i'll tell you what
24:45bring up a a a search window okay say
24:48search for command and there was like x
24:51hundred million things
24:52i said now search for commandlet and it
24:54was x
24:55thousand i said every single one of
24:57those is related to powershell
24:59and they're like oh search engine
25:00optimization there you go a little
25:03seo on the exact using the term camel
25:06and i just have to say that
25:07my wife refers to them as kimblets
25:09because that's the way they're
25:11they're spelled but at any rate
25:12commandlets now the
25:14the how a commandlet looks is also kind
25:16of bizarre
25:17if you've never been at the the command
25:20i mean if you've been at the command
25:21line
25:21you see dir but now you're seeing these
25:24well we've got verbs and we've got this
25:26dash and we've got this now and
25:27why did you so a lot of people take a
25:30look at powershell and they say oh you
25:31know ver looks very much like unix right
25:33and by the way it's just you know we
25:35actually tried to to use unix right we
25:37didn't uh
25:38start off wanting to invent something we
25:40started off saying i gotta solve a
25:41customer problem
25:43and so there were some really great
25:44tools out there the unix tools so my
25:46first effort was to get those tools
25:47available on windows
25:49but it turned out that that didn't work
25:51and the reason why is because unix
25:53is very much of a document oriented
25:56operating system which is a lot of the
25:58management is done through
25:59documents or files whereas windows is an
26:02api oriented operating system
26:05okay now both have their advantages but
26:07here's the thing the management's
26:09completely different
26:10so when i got bash and awk and sudden
26:13grep available on windows okay
26:16it didn't help that much right why
26:18because then you go and you say awk
26:20awk doesn't work against the registry
26:22grep doesn't work against
26:24wmi sed doesn't work against uh uh
26:27active directory and so in in unix those
26:30those tools those text manipulation
26:32tools
26:32are management tools but on windows
26:34they're just text manipulation tools and
26:36there's not much text so
26:38they didn't help so we had to invent our
26:40our own stuff
26:41and so then the question is okay well we
26:43want to invent as little as possible
26:46uh and so we leveraged a lot of the
26:48technology a lot of the
26:49the concepts of unix the compositional
26:51model
26:52but unix you love unix guys did a great
26:55job
26:56on the other hand it has weaknesses as
26:58well and this is an area where we
27:00looked more to vms dcl or the as400
27:04they have very good production-oriented
27:06environments
27:07and they were extraordinarily regular in
27:10their environments
27:11which is to say you had verb-noun
27:14and then this well-defined set of of
27:17parameters and what happened the first
27:19time i learned it right
27:20i was a unix guy for a long time and
27:22then i had to do
27:23vms and i got on i was like i hate this
27:26thing i despise this thing it's a piece
27:28of
27:29junk and i would go around telling
27:31everyone this and it's like okay but i
27:32got to do it for my job and i try
27:34somewhere and i just i
27:35hate it and at some point i just had to
27:37like
27:38sit myself down and like put your big
27:40boy pants on jeffrey
27:42you gotta learn this and says like okay
27:44stop
27:45get out of your head condemning things
27:47just like
27:48experience it and so about an hour later
27:51i'm like hey you know this thing's
27:52pretty cool
27:53and then all of a sudden two hours later
27:55it's like something new comes up and
27:57and having learned a set of things i
27:58said boy i wonder if that works and it
28:00worked
28:00so what happened was you learned this
28:02schema right
28:04verb dash noun or slash is there but
28:06then
28:07it was the schema you learned it once
28:08and then you were able to do it over and
28:10over and over again
28:11and that was the joke at deck at deckley
28:14used to say hey
28:15somebody put a fish finder on the vax
28:16can you manage it and they're like sure
28:18show fish finder get fish finder slash
28:20no log slash confirm
28:22and i think that's really i mean that's
28:24the epitome of what's going to help us
28:25all out
28:26not only today but going forward is the
28:28fact that you get used to
28:30i want to work with x well i know that
28:32i've got these common verbs that i'm
28:34going to use i'm going to be able to get
28:35this i'm going to be able to set this
28:37you know change it i'm going to be able
28:38to new create something new
28:41and i think that's very important and i
28:43started out in as400 and my
28:45my my first um well i was being trained
28:48my first
28:48there was a problem and my first thing
28:50was can't we just reboot it
28:52and i thought the operator was going to
28:54punch me when i
28:56said so yeah he should have so hey guys
28:58let me show you uh what these
28:59commandments are take a look at my
29:00current directory location now if i was
29:02in
29:03something like dos you guys know that i
29:04could do cd backslash but we have
29:06commandlets now so watch set dash
29:08location c calling backslash
29:11yeah that's cool now if i wanted to get
29:14something like a directory listing in
29:16dos you guys know you can do dir but
29:18here's the interesting thing we have
29:19commandlets for this so get
29:20child item will give me a directory
29:23listing if i want to clear the screen if
29:24this was dos we'd do cls but we have a
29:26commandlet for that called clear
29:28dash host please tell me that you're not
29:32impressed yet
29:34yeah i think we got the guys in the back
29:35there going yeah that was
29:38let's start to take the fear out of
29:39powershell one of the the things that
29:41helped me tremendously
29:42especially when i got started with
29:44powershell was that
29:46yes there are commandlets and yes we're
29:48going to show you how to discover
29:49and learn and use those commandlets but
29:51you can start using powershell right now
29:54even if you don't know those commands
29:55let me show you this is kind of
29:56interesting i'm going to close my shell
29:58and reopen it again
30:01and so if i want to change from this
30:03directory location back to the root of c
30:06cd oh it worked if i want to get a
30:08directory listing
30:11dir worked just perfect if i want to
30:13clear the screen
30:14cls see it's working as i would expect
30:17and here's the interesting thing
30:19let's see if i was a unix guy how would
30:21i get a directory listing
30:22um ls um how would i clear the screen
30:25well
30:26clear it's it's it's
30:29doing unix stuff and it's doing windows
30:31stuff and it's
30:32it's making me happy because i can be a
30:35windows guy and i can sit down and start
30:36using powershell
30:38a unix guy can sit down and start being
30:40using powershell
30:41my question is is why is that working
30:43yeah so what we do is we got a regular
30:45uh experience right
30:47so you've got get child items set
30:50location etc
30:51and you can always back use those things
30:53and then what we did was we put
30:54personalities on it which is to say we
30:57knew that unix guys would be coming to
30:58this we knew that dos guys would come
31:00into this
31:00and so we have aliases and so uh the
31:03aliases
31:04uh as much as possible we wanted
31:05people's first experience to not be a
31:08frustrating one that they try a set of
31:09things and they just work ps
31:11continues to work exactly and i think
31:13this is one of the interesting things is
31:16is that they're aliases and they just
31:17think of them as shortcuts
31:19to real commandlets okay so we're we're
31:22not
31:23using the actual ls command or anything
31:26it's pointing to a powershell commander
31:28but the idea was i love your use of the
31:30term personalities
31:31we built personalities into this is that
31:33it makes it comfortable for whatever
31:35environment you're coming from so that
31:36you can get started right away
31:38as a matter of fact let me just kind of
31:39show you get dash alias
31:42gives you a list of the current aliases
31:45by the way you guys should print this
31:46out and memorize this in the next few
31:47minutes so
31:48it's you have all the aliases but this
31:51is what allows you to
31:52start working and you know things like
31:54making a directory i can make a
31:55directory oh boy
31:56see i can go right to work right away
31:58and this starts to bring us to another
31:59oh
32:00we're going to talk if you're if you're
32:01a unix guy you'd use
32:03victor right right so let's see let's
32:05see make
32:06dirt this works jeffrey
32:10awesome it's it's
32:14it's all that easy um so basically your
32:18normal command line experience you can
32:20bring right to powershell but wait
32:22there's more okay yes there's more
32:26there's more get a ginsu knife out of
32:28this
32:28even better than against a knife now
32:30first of all i just want to kind of
32:31point out that
32:32we're going to talk about help
32:34extensively but if you want to get help
32:36you can type help and if you're a unix
32:39person and want to type help you can
32:40type man now personally i think
32:42you know unix is kind of sexist for the
32:44whole man thing but in powershell if you
32:46want to get a list of
32:47if you want to get a list of aliases you
32:49can type get dash alias
32:51but there's an alias for get alias
32:53called called gal and see this is what
32:55makes me so happy is that
32:56powershell isn't sexist so you should
32:57use this um anyways
33:00let me show you stupid but
33:03so here's where it gets really cool
33:08you know what i can do from powershell
33:09besides working in an environment that
33:11already kind of feels comfortable
33:12with me i can i can use windows native
33:15commands i love this ping
33:20a computer and it works this is so
33:23awesome yeah
33:24i can run notepad i can i can i oh yeah
33:27i know everybody's impressed now i can
33:28oh look calculator
33:30and oh hey you know what i haven't tried
33:31this yet on windows 8 i should try this
33:33can i run do we still have ms paint oh
33:36this is awesome so we still
33:39okay but the point was this is that
33:43you can still use your windows native
33:44commands in here you guys are always
33:46checking you know ipconfig and all that
33:48stuff
33:49don't don't be that guy or that gal i i
33:52have to tell you this is one of the
33:53funniest things i have
33:54i was teaching an advanced scripting
33:56class for for powershell this guy
33:57i've known him a long time was writing
33:58this magnificent tool
34:00to go out and do a bunch of things to a
34:02couple of computers
34:04and he said you're going oh my script's
34:06broke can you help me and i'm like
34:07what's your problem he says well the
34:09scripts broke and because
34:10it's getting those two machines but it's
34:12not getting anything from that machine
34:14and one time i said well first of all
34:16don't forget you're an engineer
34:18what do you what do you usually do if a
34:20machine's not responding how do you
34:22test that and he says oh oh
34:25i'll ping it i'm like yeah see if it's
34:27even turned on very good very good
34:29so he's sitting at a powershell console
34:31no
34:32you know what he did yes start programs
34:35accessories opened up command
34:37prompt to type ping i literally looked
34:40at him
34:40and went get out
34:42[Laughter]
34:44so the idea guys is you have your
34:46windows native commands
34:49and they work the way that you expect
34:50them to work so that you have an
34:52environment to get started in so
34:54between aliases helping you out and
34:57between running windows native commands
34:59the idea is open up powershell don't
35:01open up the command prompt
35:02open up powershell and start using
35:04powershell because you're going to start
35:06then learning the commandlets and
35:08which we're going to do today but you're
35:10going to start learning the commandlets
35:11and make your learning curve much
35:12easier this way it was designed for you
35:14to do it this way
35:16and so make your life easy and just go
35:18ahead and start using it and make sure
35:19you show your other administrative
35:20friends
35:21open up the shell and start using it
35:23it's going to work
35:24for you so at least that's taking a
35:27little bit of the fear out of it
35:28let's hope so besides having aliases and
35:32all that kind of good stuff folks we
35:34want to do kind of a reminder for you
35:37oh wait can you go back oh yeah i can go
35:38back yeah can i can can i show you
35:39something
35:40you can go to my screen okay
35:44hoo-ha perfect let's see okay so i don't
35:47know if you know this but uh so
35:48the aliases right so you saw aliases for
35:51gal pwd right okay
35:55so they're these personalities yeah okay
35:58but
35:58if you take a look there's just a ton of
36:01these things
36:02yeah and so so you notice like what are
36:04they alias too it's all verb noun verb
36:06noun
36:06sorry yeah okay uh but the aliases are
36:09very regular as well
36:11okay so take a look at this let's say
36:13gal well gal
36:14g star okay notice wild cards
36:17so notice all the g's start with get
36:21okay you know what i i don't think i've
36:23actually ever noticed that
36:24okay now here's the thing now that's
36:26that's sort of obvious right
36:27but apparently not because but
36:30here's the interesting thing look at
36:32this one g as v okay let's let's see if
36:34i can zoom it working here
36:36okay oh look at that okay so get service
36:39gsv so then the question is well geez
36:42what about if i did gal star sv
36:47and look there okay so you've got some
36:49so gsv
36:51saesv start service spsv
36:55stop service so look at this sasv
36:58okay so let's see oh i'm getting good at
37:01this
37:01sasv is start service so
37:05sv for service let's say gal sa star
37:09and look start start starts so it's not
37:11always the case right
37:12cell al for alias but yeah sa
37:15jb so we've even been tried to be
37:19thoughtful and and schematize the
37:22the um the aliases as well and you made
37:24them easy to
37:26search through and this has become
37:28really important when we get to
37:29start talking about using the help
37:31system which is what we're going to do
37:32next
37:33but you've made them easy to search
37:34through to find aliases and one of the
37:36things
37:37guys i want to show you is a is on to
37:39what jeffrey was showing you
37:40is with those aliases um
37:44a lot of times get alias a lot of times
37:46you're going to have a commandlet and
37:48you're going to want to know what the
37:49alias is for the commandlet
37:51there is a way to do this and we're
37:52going to explain what parameters are
37:54they alter the command and there's a
37:56parameter called definition and if i
37:57were to type in
38:00a particular commandlet it'll tell me
38:02what the aliases are available for
38:03notice in this case there's a couple of
38:05them ps and gps for it
38:07um so there's a couple of different ways
38:09to find and work with your aliases i
38:11find it much easier if you just memorize
38:12the list
38:12no just kidding don't memorize the list
38:15as a matter of fact don't
38:16memorize anything but we'll we'll talk
38:18about that more yeah
38:19good um so because we don't want you
38:21memorizing stuff yeah that just takes
38:23the pain out of it
38:24so questions or comments make sure that
38:27you're in the chat rooms you're asking
38:29questions
38:29and we're going to be checking on you
38:31guys as we go throughout this
38:33to see if you have any questions and
38:35there will be a recording of this later
38:37i know a lot of people are asking if
38:39there's going to be a recording of this
38:40absolutely and it will be available for
38:42you online with mba
38:44so and i'm going to remind you with this
38:45slide often to ask questions
38:47and stuff like that
39:04[Music]
39:13so you're ready to uh do a little help
39:16and help me out and
39:18do a little help help help yeah because
39:21guys this is probably the most important
39:24section of the entire day and it may not
39:27even seem like it at first but i swear
39:29to god that this is the most important
39:31thing and here's why it's so important
39:34when you go to powershell you're going
39:36to stare at that console and go
39:38now what do i do yeah this is the answer
39:41so
39:42kicker girl card called that the
39:44dizziness of freedom
39:45you look at that prompt and you can do
39:46anything you're like uh
39:48what do i do and that is that a lot of
39:50it it affects all of us and
39:52a lot of us you know you get past that
39:54with what we're going to do
39:56now yeah it's a help system um but i
39:58think for a lot of folks i see it all
40:00the time that
40:02okay it made sense when you were doing
40:04it but now i'm staring at that console
40:06and
40:06i just don't know what to do and i don't
40:09know where to go
40:10and they created a solution for you this
40:12is a beautiful solution so what we're
40:13going to start off with
40:14is looking at the help system
40:17showing you how to get it updated and
40:19this is actually a fascinating feature
40:20in v3 remember i was saying you're going
40:22to want to be using v3 and this is going
40:23to be one of them
40:24the most important thing is the
40:25discoverability that the help system
40:27provides you
40:29basically it is your it is your bang for
40:32power shell it is your
40:33it is it is answers all of your needs
40:35and all of your questions
40:37and also we're going to show you how to
40:39read syntax and so forth so
40:41let's get started with the help stuff
40:43and here in about 10 minutes we'll take
40:44a break and then we'll come back in and
40:46look at all the syntax and
40:47start getting into it so first of all
40:49why you need
40:51help well i just want to go to bullet
40:54number two
40:56exactly can can we talk about this i
40:59don't
40:59i'm a smart guy but i'm not smart enough
41:02to just know everything
41:04absolutely so tell me what the idea here
41:06is yeah so
41:07one of my jokes although it's actually
41:08true is that uh powershell is such a
41:10great product because i'm such a deeply
41:12flawed human
41:14okay it's true i'm a deeply flooded
41:17human and i was in a position to say hey
41:20let's build a tool that helps me
41:22right so concretely you know i i can't
41:25remember all that stuff either i'm a
41:26terrible typist
41:28uh et cetera so you'll see there's a ton
41:30of stuff in powershell
41:31that helps for those things so really is
41:34a goal to not be able to memorize things
41:36actually there's a great story they
41:38recently did a study
41:40of unix admins and came out with this
41:42report and i was
41:43really amused by this because basically
41:45about 25
41:4630 years ago they had done exactly the
41:49same study
41:50and produced exactly the same results
41:52and here's what they did
41:53they took a bunch of beginner unix
41:55admins and
41:56expert unix admins and they said hey
41:58here's a test
42:00if you want to do this how do you do it
42:01a written test and what was interesting
42:04was
42:04that there when you scored these uh
42:06there wasn't very much of a difference
42:08between the
42:09expert unix admins and the beginning of
42:11unix admins
42:12and so then it's like oh why are we
42:14paying these experts so much money you
42:15know they can't uh
42:17objectively they're not that much better
42:20than just some
42:21beginner right and so then so then they
42:24said okay
42:24well now let's put them in front of a
42:26machine and give them a set of tasks
42:28and what you saw was this huge
42:31difference in performance
42:32that the experts were able to perform
42:34amazing things
42:35that the beginners struggled with and
42:37the conclusion was
42:39that what expert unix guys are great at
42:42is not
42:42knowing things but in figuring things
42:45out
42:46okay and so that's the deal this is not
42:49about you sitting there saying
42:50hey um it should work this way
42:53right no no that's not the deal the deal
42:55is hey let me figure out
42:58how to do things and so that's what it's
43:00all about what you're going to learn
43:01is a schema right you're going to learn
43:03a set of things you're going to learn
43:05how to learn
43:06and then you're going to use those
43:07techniques over and over again
43:09and that's why once you learn how to use
43:11powershell and you're managing say
43:13exchange
43:14then when someone says oh we got this
43:16link server it's like well let me have
43:17at it
43:18and you'll be able to go and you'll be
43:20able to learn and learn and learn
43:21and just figure stuff out so basically
43:23what you're telling me is is that
43:25the first time i walked up to a unix guy
43:27and i said hey how'd you do that and he
43:28turned around
43:29and usually barked uh barked at me going
43:33rtfm yeah he was actually trying to
43:35educate me
43:36he wasn't just being a terrible person
43:39no both
43:40oh okay but i think
43:43and this is really the moral of the
43:44story is you're not gonna be able to
43:46memorize stuff guys
43:47we you know powershell v2 had like 236
43:50core commandlets
43:52okay i might be able to memorize those
43:53but here's the deal when you start
43:54working with products
43:56you know exchange has depending on your
43:58version of exchange has between 535 and
44:00610 commandments
44:02you got 500 some odd commandlets for
44:03sharepoint you've got a hundred and some
44:05odd commandlets for active directory
44:08in server 2012 you have thousands of
44:11commandlets now there's no way
44:15to memorize them so what they did is
44:17they created a help system now
44:19before you go oh no not another help
44:21system
44:23because i know if you've and i'm i'm not
44:25okay maybe i am if you've used the help
44:27system in
44:28in in a particular product before and
44:30have found it unuseful
44:32well just remember it wasn't spent a lot
44:36of time on this was spent a lot of time
44:38on by people who
44:39wanted you to be successful knew that
44:41the only way that you're going to be
44:42successful is to have
44:44a great help system we all of us use
44:47this
44:48every single day and i want to point out
44:50that as jeffrey was saying it's about
44:52using the help system reading and
44:53comprehending it
44:55and then figuring it out we're i.t pros
44:58that's what we do we figure things out
45:00this is actually fun when you get start
45:03working with
45:04it but one of the challenges that we
45:05have is the rtfm
45:07side i mean as an it pro one of the
45:09reasons i got into it is because i was
45:10really good at sitting down at a
45:12computer and just figuring it out
45:13i didn't have to read the manual well
45:16that's not going to work here we're
45:17going
45:18to have to use and read and comprehend
45:20the manual and they've made it
45:21really easy for us so let's start doing
45:24a little get
45:24help stuff first of all and guys
45:28some of this stuff is in the slides and
45:30so we're just going to demonstrate it
45:31first of all let's talk about
45:33um update help versus the way that we
45:35used to have it
45:36yeah okay so we used to ship the help uh
45:38with the product
45:39and uh turned out that that was there
45:41were all sorts of problems with that
45:42so basically the way microsoft works uh
45:45because we ship
45:46to hundreds of millions of people right
45:49um
45:49it really matters that the release is
45:51buttoned up right which is to say that
45:53you stop
45:54changing things and then you test and
45:56you test and you test and you test and
45:58then you release it
45:59so what ended up happening was um that
46:01just as soon as you're
46:02like finishing putting the finishing
46:04bits on the the code
46:05the documentation has to be done and and
46:08of course that doesn't work
46:10but now it's cooked like hey don't
46:11change it because you might break
46:12something
46:13so then it gets shipped and and the
46:16documentation there's differences
46:17between the documentation and the
46:19and the product and the answer used to
46:21be well you know hey just hang in there
46:23you know we'll release again in three
46:24years and we'll fix that well that's
46:25kind of a crummy answer
46:27and then there was a second problem the
46:28second problem is guess what the help
46:30is huge right because there's a ton of
46:32it
46:34and then would you say well geez i'm now
46:36going to a
46:37cloud world where i've got a gazillion
46:39machines i get a gazillion servers won't
46:42want to
46:42to use those be as efficient as possible
46:45with those servers
46:46and you don't need the help on all those
46:48servers right you need the help on the
46:49machine you're managing them from
46:51and to put the help on all those systems
46:53is just load you know bogging down those
46:55servers with
46:56stuff that you're not going to use so
46:58because of those two problems in windows
47:00or certain powershell version three
47:01we move to an updatable help model which
47:04is to say
47:05we ship and there's some very uh kind of
47:07like structural help
47:08that we generate based upon metadata
47:11you'll see some examples of that
47:13but then all the help text is available
47:16from download from
47:17from the internet so that's the way that
47:19works and and let me just say that
47:21in v2 one of the challenges was if
47:23you're using the help system and there's
47:24an example in there there was a
47:25possibility you know that maybe that
47:27example was wrong
47:28and i'll show you a way around that if
47:30you're in v2
47:31um to get the latest information for it
47:34but really the joy here with v3 is
47:36is as soon as microsoft updates a helper
47:39they find an issue
47:40my help gets updated on my management
47:42station so the first thing that we're
47:44going to do and then we're going to take
47:45a break here and just like
47:46can i give an example yeah so i don't
47:47know if you ever use wql
47:49yeah okay right so i can never remember
47:51wql
47:52i just can't it's one of those things
47:54well there's certain things that just
47:55never sink in for me wql is one of them
47:59and so constantly whenever i want to use
48:01that i'd have to do search and there's
48:02something about the
48:04search the content i can never find it
48:06on the internet either
48:07right and so at some point somebody had
48:09this exactly the same problem so they
48:10went
48:11on microsoft connect and said you ought
48:13to have an about topic for
48:15for wql and guess what they went and
48:18wrote one
48:18and so now we have an about wql and it's
48:21just there
48:21point was you didn't have to wait for
48:23another release you had a problem
48:26you told us about your problem and we
48:28responded and then in a matter of like
48:30well i forget how long that one took but
48:32there was one where somebody complained
48:34about an error in the documentation two
48:36days later we had an update
48:38so this is pretty pretty peppy it's
48:39continuous publishing and so what you
48:41want to make sure that you're doing is
48:43you're updating help and let me show you
48:44how to do that first of all
48:46you're going to need an internet
48:47connection now there is a way around
48:48that but let's just start off with the
48:49basic update help here and so we've got
48:51a commandlet for that called
48:52update as update get it dash
48:55what would you have how did you want to
48:57update yeah what do you want to update
48:58the help
48:59so the verb the noun so that's working
49:01out and i like to use dash force and
49:03guys
49:04this is something that you can run every
49:05single day to make sure you have the
49:07latest and greatest help
49:08and what it's going to do it's going to
49:09go out to the internet and it's going to
49:10download
49:11all of the help files that you need for
49:13all of the stuff that you have on your
49:14system see that progress
49:16bar says ooh which is what it should say
49:19in powershell
49:21so cool now look if you have a siri a
49:24bunch of machines that don't have direct
49:25access to the internet you can
49:27save this help with save
49:30help you can save this help you figured
49:33it out
49:34as a set of files and then you can
49:36update
49:37from that set of files but having the
49:39internet connection sure does make your
49:40life a lot easier
49:41now here's the idea we're going to take
49:44a break here
49:45and so what we want to do is make sure
49:47that you've got a powershell console up
49:49and make sure that
49:50you've updated help because when we come
49:53back we're going to start using
49:55my favorite things and let me just show
49:56them to you real quick
49:58get dash help which yep that's going to
50:01get us help on stuff
50:02but it's also going to help us search
50:05for stuff and so that's its most
50:06important thing
50:07before though we go i want to show you
50:10there's a difference you're going to see
50:11people use get
50:12dash help you're going to see people use
50:14help
50:15and you can see people use man and i
50:16want to show you that there's a
50:17difference between these two
50:19get dash help and i'm just going to pick
50:21a commandlet and what i'm going to do is
50:22i'm going to keep things real simple
50:23right now
50:24and i want you to notice my screen it
50:25scrolled all the way to the bottom
50:27now this is not a complete help file but
50:30we'll get to that
50:30after break but i want you to notice it
50:32scrolled all the way down to the bottom
50:34now watch the difference between
50:36using help on the same thing
50:40look at the bottom of the screen see how
50:42i've got that little more
50:44so i can and you probably heard that i
50:46can spacebar now and
50:48and move through the help file man does
50:50the same thing
50:51so man and i'll do get service
50:55gives you that same you know like you
50:57pipe to more kind of deal
50:58where you can pound your way through it
51:02use whichever one makes you happiest and
51:04probably today you should experiment i
51:06know i've got friends that are
51:08just help i always only use help i
51:12happen to be a get dash help kind of guy
51:14because i like it to scroll to the
51:16bottom of the screen the help system is
51:18a super discoverable
51:20great tool to help me find things
51:23and and let's do a couple of examples
51:25i'll start off and then you can join in
51:27guys this is this is going to be really
51:29awesome because and don't memorize
51:32or write down anything that we do yep i
51:34swear to god don't
51:35do it because that's kind of the whole
51:37point so let me give you an example
51:39first of all help
51:40has the ability to discover stuff and
51:42i'm gonna i'm gonna get help get dash
51:43help kind of guys so i'm gonna use git
51:45dash help
51:46and i wanna find out here's here's my
51:48here's my i wanna see if there's
51:49any commandlets that could help me work
51:51with
51:52services so i'm going to do star service
51:56star
51:57yeah by the way star is your friend star
51:59is a wild card and it says
52:01find anything at the beginning or find
52:03anything at the end match anything at
52:04the beginning or then
52:05yeah and make sure that when you mean
52:08wild card you use a wild card because
52:10some commandlets will let you
52:12not use the wild card and that's not a
52:14good practice to get into so
52:16oh my gosh look at all of these
52:17commandlets so many commandlets that
52:19have
52:19service in them whoa but now is where
52:22the fun begins
52:24look is there a commandlet that in this
52:27list that looks like
52:28it might retrieve or i don't know get me
52:31a list of services on my computer so
52:35yeah there happens to be one right here
52:37see get dash service
52:38it would probably get me a list of
52:41services
52:42show them the up arrow oh show me up
52:44here
52:46you can just use the up arrow now watch
52:48this now use the right arrow
52:50right left arrow left arrow and put a g
52:52in front of the star
52:53check this out now do it
52:57oh got a short list these wild cards are
52:59great the wild cards are great and
53:00actually knowing how to do a good search
53:02is really good
53:03oh this is great this is great so here's
53:06the idea and we're going to do this a
53:07couple times the idea is you
53:08search for and probably by noun you
53:11search for the thing that you want to
53:13find
53:13i want to know something about processes
53:15or i want to know something about
53:17services which are the examples i'm
53:18going to use a lot but it could be as
53:20simple as
53:21ad computers or something like that you
53:24search for what you want and when you
53:25find it
53:27well there's a help file for it so let's
53:28go in and take a look i'm going to do
53:30get help
53:31get dash service now this is the simple
53:34view of the help file and let me just
53:36show this to you real quick
53:37it gives you the name synopsis syntax
53:40which we're going to talk about here
53:41shortly
53:42gives you a description of what the
53:43commandlet does and some related
53:45links and information now this is not
53:48the full help so don't panic we're going
53:49to do the
53:50the full help but let's try this
53:52discovery thing again i want to do
53:53let's see get help and i want to find
53:56something that would oh and i'm going to
53:57use your trick i'm going to say that
53:58would uh
54:00g star something with
54:03a d computer in it because i want to
54:06i want to work with active directory
54:08computers oh
54:10look there's there's a command there get
54:12a d computer you know what i'm thinking
54:14i'm thinking in my head
54:15that's probably gonna solve my problem
54:16but to be sure what i'm gonna do is
54:19do get help get ad computer
54:23and take a look at it
54:27and again this is the simple help view
54:30and we'll get to a
54:31better ones here in just a second but so
54:33the concept is is pretty simple what you
54:36want to do
54:36is you want to discover what you want to
54:39work with
54:40and then look at the help for what you
54:41want to work with now the concept is
54:43simple but doing this
54:45seems to be a big challenge for a lot of
54:47folks i you have to become
54:49trusting in that this is how we do it
54:52and this
54:52actually works no matter what product
54:54you're working with
54:55think of what is it that you want to do
54:58something to what
54:58what's the noun that you want to find
55:01and
55:02then have help search for it yep sounds
55:05like a great way to get help to work for
55:06it yeah we very much
55:07tried to create a world where you could
55:09think about what you want
55:11type it and get it okay so let's just
55:13say you wanted to assign something well
55:15you'd look for a sign you wouldn't find
55:17that and you'd
55:18then quickly learn that we use the word
55:20set
55:21and so you'd say well okay so there's an
55:23infinite number of nouns
55:25but the verbs are pretty regular so
55:26imagine you wanted to get the help on
55:29the verbs like yeah you type you type
55:32who are go ahead okay so what you do is
55:35you say
55:36you say get verb
55:40and it shows you all the verbs and so
55:42these are all the verbs that you you
55:44you're going to learn and you see well
55:46how many are there so you might want to
55:47say well i'd get the verb
55:49i'd like to measure them and you see
55:51that there are 98 verbs
55:53and here you see we break them up into
55:55into
55:56you know um whether they're security
55:58verbs or communication verbs etc
56:01anyway so those you're going to learn
56:02those 98 things and then
56:04and then you're going to be able to
56:05think type and get what you want
56:07and what what happens often is you're
56:10not even going to learn all 98 of those
56:12you're just going to learn
56:13a few of them because you'll know that
56:14what the verbs will do for you and you
56:15end up looking for the nouns so
56:17it becomes a very easy process to follow
56:19through but let's start getting into
56:21what this help can do for us so once
56:23again i'm going to do this
56:24get help i want to find commandlets
56:27that'll
56:28retrieve me some services now notice
56:32well there's get service and so i want
56:33to take a look at what this
56:35can do for me so i'm going to do get
56:37help and get
56:39service again this is the simplified
56:41help view but there's more to help than
56:42just this
56:43once you've updated help this help can
56:46be extended or expanded upon and let me
56:48show you a couple of things this is
56:49where it gets oh
56:50just so happy for me because
56:53watch i'm going to do get help on git
56:55service but
56:56we have a parameter that will allow us
56:59to get
57:00detailed ooh detailed help
57:03and here's what detailed help is going
57:04to show us i'm going to scroll all the
57:05way back to the top
57:06and get service gives you the synopsis
57:10again the syntax which we're going to
57:11talk about in a second and the
57:12description this is what we saw before
57:14but here's this when we talk about
57:16syntax we're going to start talking
57:17about what these things are
57:18parameters these parameters change how
57:21the commandlet
57:22acts well i don't necessarily know what
57:25these things
57:26mean well when you go to detailed help
57:29look
57:30the parameters are listed here with an
57:32explanation of
57:34what they mean and so what you'll do is
57:36you'll
57:37actually be up here looking and going i
57:38have no idea what that is and then you
57:40can just scroll down and get a
57:41definition of the parameters
57:43also as i scroll down here i want you to
57:45notice something really interesting
57:48now we start to get examples now i want
57:50you to think about this for a second
57:51i've got a command called get dash
57:53service so let's think about what it's
57:54probably going to do i haven't run it
57:56yet
57:56it's good probably going to give me and
57:58if i read the description
57:59a list of all of the services on my
58:01computer
58:02whether they're running stopped or
58:04paused and it'll tell me about that
58:06how many examples of that do you really
58:08think we need
58:10well we need 11 of them and here's
58:13here's here's why i want to point this
58:15out we
58:16apparently we need 11 examples of this
58:18and there's a reason for this
58:20because the people that worked so hard
58:22on these help files
58:23knew that there were going to be all
58:25kinds of different ways that you're
58:27going to want to try to use this and
58:28they wanted to give you examples
58:29what happens is this is oftentimes
58:31you'll be thinking of a business problem
58:33or trying to solve a business problem
58:34and you'll say gee whiz let me go i
58:36found the command let me go look at the
58:37example
58:37you'll find an example that is really
58:40close
58:41to probably exactly what you wanted to
58:43do
58:44which is one of the cool things so a big
58:45shout out to all the folks that work on
58:47you know the other thing we did was
58:49there were a few of the ones we knew
58:50people were going to use a lot like get
58:51process boy you always want to spend
58:53time looking at get process
58:55because there what we did was we said
58:57hey get process get serviced people are
58:59going to use these a lot
59:00and so in our help and our examples we
59:02show you not just how to use get process
59:04and get
59:05service but we also show you some very
59:07common powershell techniques that then
59:09help you
59:10you kind of lead you to the next step
59:12you start off saying oh i'd like to get
59:13something to get services what do i want
59:15to do
59:16and then you say well geez actually i'd
59:17like to format it a little differently
59:19or i'd like to find these things filter
59:21and so we use those high volume topics
59:24to kind of go a little bit deeper to
59:26teach you the next level of powershell
59:28which is you're going to as we take you
59:30through learning all of this deep level
59:31part of powershell you're going to look
59:32at these help files in a totally new way
59:34and you'll see that
59:35examples of sorting and filtering and
59:38getting the kinds of information that
59:39you want and changing the kinds of
59:41information you want
59:42a lot of times writing the examples a
59:44lot of people the first thing they do
59:46is they go to examples as a matter of
59:47fact there is rather than detailed
59:49you have a parameter called examples
59:52that will take you right into just the
59:54examples if you want to get there real
59:55quick
59:56something else that you can do and this
59:59is going to become
1:00:00a big deal this afternoon as we work
1:00:02through this
1:00:03there's also full help i don't know
1:00:06jeffrey i don't know if they can handle
1:00:07the full help
1:00:08i mean that's that's that's an awful lot
1:00:10that's stress testing that says
1:00:12here we go full help put your seat belts
1:00:14on put your seat belts on
1:00:16um full help guys i'm going to tell you
1:00:18right now the full help is very similar
1:00:20to detailed except when you're in the
1:00:22parameters
1:00:23there's some special information and
1:00:24this is going to make in the next
1:00:26section when we're going to talk about
1:00:28what this information means to you it's
1:00:29actually very important to us
1:00:31and this will help us understand how the
1:00:33commands work in the pipeline and so
1:00:35we're going to talk about
1:00:36that stuff in a little bit so right now
1:00:38when you're running get help
1:00:40you can use detailed or you can use
1:00:42examples but
1:00:43a little bit later on you'll always end
1:00:45up using full
1:00:46now i want i promised you earlier that
1:00:48for the you folks that are running
1:00:49powershell v2
1:00:51and even if you're running v3 um
1:00:53sometimes if you're running v2
1:00:55your help files they're not up to date
1:00:57and you want the latest
1:00:59i need the latest and greatest
1:01:00information well you can't run update
1:01:03help if you're in v2 which is
1:01:04why on your admin box you should be
1:01:06running v3
1:01:08however let me just show you this is how
1:01:09we used to get around that
1:01:11microsoft helped us with this dash

1:01:27for whatever it is that i was looking
1:01:29for in this case get service
1:01:31so again don't close that i'll lose the
1:01:34chat
1:01:35dash online now i can't show my favorite
1:01:38yeah because
1:01:39you i that oh i hope you do now this i
1:01:41was confused by this at first but
1:01:43go ahead but what well yeah i'll show
1:01:45you you go okay
1:01:46so let's talk to mine so here we do get
1:01:50get help help
1:01:53get service so here's the thing you can
1:01:56say
1:01:57examples right examples
1:02:00and they say oh that's cool let's let's
1:02:02let's run this let's let's let's let's
1:02:04uh
1:02:05let's do one of these okay and type that
1:02:08and by the way so you do you do enter
1:02:11and then left mouse button and okay
1:02:14great now you want to do the next one
1:02:16oh well so you see the workflow's all
1:02:20messed up
1:02:21so what you can do is you can say
1:02:25get help minus show show window
1:02:29and look here comes up in a window okay
1:02:32now this has all sorts of great stuff
1:02:35one of these is
1:02:36settings and you say hey i want to just
1:02:39see
1:02:40i don't want to see all this stuff i
1:02:42just want to see
1:02:44the examples look at all the stuff you
1:02:46can have control over
1:02:48it's amazing to me so now you just go
1:02:50here
1:02:51cut paste sorry paste
1:02:56and do that and then the next one
1:03:01cut paste and so it's a very nice
1:03:04workflow
1:03:05much nicer workflow so again that is
1:03:08this
1:03:08this show window
1:03:12and you'll see there's some really fun
1:03:14stuff with show window can i spend some
1:03:15more time with you
1:03:16absolutely okay so now let's turn all
1:03:17this back on there
1:03:19okay so you see it's got lots of stuff
1:03:22here
1:03:24okay so now in the show window you can
1:03:27do things like remember i said what is
1:03:29it
1:03:29anyway you've got to find here right so
1:03:32you can find stuff like
1:03:33dependent depend
1:03:36okay and so notice it gets highlighted
1:03:38and it says here
1:03:39it says 18
1:03:43matches okay and
1:03:46and it could search i don't do that very
1:03:48well anyway so then you can start
1:03:50searching for these things
1:03:51and so it's it's super nice i and i
1:03:54think the addition of this this was
1:03:55added to v3 and i think the addition of
1:03:57this
1:03:58is really phenomenal because guys let me
1:03:59show you um traditionally
1:04:02you're going to spend so much time in
1:04:04the help file and you're going to want
1:04:06to do just that you're going to want to
1:04:07cut and paste from a help file or you're
1:04:09going to want to read a help file while
1:04:11you're working in powershell
1:04:12that a lot of times what a lot of guys
1:04:14would do is if you take a look at my
1:04:15screen i'm gonna
1:04:16well yeah i'm just gonna launch two
1:04:18powershell sessions now if you have two
1:04:19monitors
1:04:20this is great right so you do help in
1:04:22one
1:04:23and then you can work in another one but
1:04:25with v3
1:04:27having the show window stuff
1:04:32well first of all it fits better on your
1:04:33screen it's easier to move around
1:04:35you can have the help it's easier to get
1:04:37stuff out the part that always confuses
1:04:39me is
1:04:40and then we're going to fix this later
1:04:41when we start talking about the magical
1:04:43ise but it's it's the cut in the pace
1:04:46man
1:04:47it's that whole yeah it's that right
1:04:49clicking and
1:04:50stuff in the console why can't we fix
1:04:52that why can't we fix that why can't we
1:04:53fix
1:04:54that that that console because it's
1:04:57horrible
1:04:58yes that's the answer no so here's the
1:05:01thing
1:05:01here's the thing so let me give you a
1:05:03little
1:05:04tutorial about some of the behind the
1:05:07scenes stuff at microsoft so
1:05:08there was some point where people said
1:05:10oh you know microsoft stopped
1:05:13advancing i.e you know oh that just
1:05:15proves what bad guys they are
1:05:17there's no competition they stop
1:05:19innovating no no no my friends honestly
1:05:21that's not what happened
1:05:22what happened was um was that it got to
1:05:25the point where every time we made a
1:05:27change
1:05:28uh we broke a bunch of people right
1:05:30right and so then it's like well
1:05:31people are like hey jerks stop breaking
1:05:34us
1:05:35and so and so they stopped doing that
1:05:38and then all of
1:05:38a sudden some competitors got up there
1:05:40and so now they went and started
1:05:42doing things even though sometimes
1:05:44things break
1:05:45same thing happens with the console
1:05:46window the console window man
1:05:48every time you change that thing you
1:05:50break tons of people
1:05:52you just break tons of them and so you
1:05:54don't want to change that thing very
1:05:56much now here's the thing
1:05:57actually i'm pretty hostile to the
1:06:00console window
1:06:01okay so that's it i'm trying to make
1:06:02this thing die i'll just be
1:06:05straight up about it make it y die and
1:06:07why is that and the answer is
1:06:09that there are these things called
1:06:10console apps okay now a console app
1:06:13only works in the console now here's why
1:06:16i want to kill the console because i
1:06:18want to kill
1:06:18console apps and it turns out that the
1:06:21reason i want to kill console apps is
1:06:23you go and you write you do something on
1:06:24the console app and it writes directly
1:06:26onto the console
1:06:28which means you cannot automate it okay
1:06:30you can't
1:06:31run something get its output process the
1:06:34output and do something with it because
1:06:36it writes directly on the screen
1:06:38so this is just evil incarnate it is the
1:06:41enemy of automation so we're trying to
1:06:42get rid of those things
1:06:44so we're trying to uh get everybody on
1:06:46to powershell ise
1:06:48which is a much richer investment so by
1:06:50the way stop
1:06:51asking me to fix the console i'm not
1:06:53going to fix the console
1:06:54and that's the point that i want is that
1:06:56the console and look i know cut and
1:06:58pasting in the console and some guys ago
1:07:00the console's driving me nuts a little
1:07:01bit later on today we're going to help
1:07:02you with
1:07:04well he hates it and so there's actually
1:07:06a really cool solution to it but i want
1:07:07you to wait till we get there with the
1:07:08isc
1:07:10so to cut and paste in the console is
1:07:13if you haven't done it yep it's you
1:07:15highlight it you right click
1:07:17and then you can right click again so no
1:07:20control c no control v
1:07:22in this puppy i think we
1:07:25may have something cooler for you later
1:07:26on but right now
1:07:28that's how you do it so right click and
1:07:30right click will take care of it for you
1:07:32jeffrey you know what we need to do we
1:07:33need to start to take a look at
1:07:36and explaining syntax because here's the
1:07:40thing
1:07:40everybody wants to work with uh
1:07:43commandlet but
1:07:44you know commandlet's going to do great
1:07:45stuff for you but sometimes you want the
1:07:47commandlet to
1:07:48alter its output or change what it's
1:07:51actually doing for you you know get
1:07:52service is great but it's going to give
1:07:54you a list of all your services
1:07:56i maybe i just want the one called bits
1:07:58or something like that
1:08:00so the syntax of the command will
1:08:02explain to you the options that you have
1:08:04available
1:08:05to control the commandlet and so at
1:08:07first it looks very very confusing now
1:08:09we've got slides for this and so it's
1:08:12all in the slide deck
1:08:13but let's take a look here i've got get
1:08:15service up right now and i'm going to
1:08:16take a look at something pretty simple
1:08:17you know
1:08:18if you do this in show window it comes
1:08:19out better you like it in show window
1:08:21better yeah
1:08:21cause watch do it oh you oh no you're
1:08:23doing it let's see
1:08:26let's do show window see because one you
1:08:29got the zoom there
1:08:31down at the bottom did you ever notice
1:08:33that
1:08:35oh yeah yeah
1:08:38let's see and so the nice thing is that
1:08:39it highlights some things so it's a
1:08:41little i think it's a little bit easier
1:08:42to read
1:08:42very easy and it's easier to select and
1:08:45say
1:08:47okay so we're going to use we're going
1:08:48to use this instead this is much better
1:08:50so take a look at this right here see
1:08:52the thing with the dash in front of it
1:08:54so you'll notice that i've got a command
1:08:56lit
1:08:57and then it starts followed by all of
1:08:58this magical characters we're going to
1:08:59explain what all these characters are
1:09:01but the first thing i want you to notice
1:09:02is look how many times under syntax
1:09:05i see the name of this command line i
1:09:06see it three times now jeffrey
1:09:08technically this is called
1:09:09parameter sets but parameter sets why am
1:09:12i seeing three of these
1:09:13yes so here's the thing imagine uh take
1:09:15a look at the net command
1:09:17right there's net use and net view
1:09:20et cetera these are different parameter
1:09:23sets
1:09:23and what happens is when you type net
1:09:25view you get one set of functionality
1:09:27when you type net use you get a
1:09:29different set of functionality
1:09:30so what happens is that that then they
1:09:33reuse the word the command net
1:09:35now that's essentially what a parameter
1:09:38set is now we take a different take on
1:09:40it
1:09:40net use is extremely different
1:09:43functionality than net
1:09:44use okay so we don't like that we want
1:09:47to be
1:09:48clear but the point about get service is
1:09:50that there are different parameter sets
1:09:52sometimes you want to say
1:09:53get service based upon its name or
1:09:56you're going to say i want to get
1:09:57service based upon its display name
1:10:00okay so those are two different
1:10:01parameter sets so a better example would
1:10:03be
1:10:03get process sometimes you want to say
1:10:05get process
1:10:06whose name is this sometimes you want to
1:10:09say get process whose id
1:10:11is this or sometimes you're going to
1:10:13just say get process
1:10:14and get them all and get them all yeah
1:10:16so those are different parameter
1:10:17sets and let me show you what jerry's
1:10:19talking about is notice in these
1:10:21three different get services and yeah
1:10:22don't worry we'll take a look at get
1:10:23process too
1:10:24and these three different get services
1:10:25look at this one this one has dash name
1:10:28down here in these other two you don't
1:10:30see dash name
1:10:31this one has dash display name you don't
1:10:33see that in the other two so that's what
1:10:36makes that particular parameter set
1:10:39unique and matter of fact i'm going to
1:10:40demonstrate these here in just a second
1:10:42but again look at these dashes
1:10:45these dashes indicate that they're
1:10:47parameters
1:10:49dashes parameters parameters will allow
1:10:52you to change the results of what the
1:10:54command is going to do and i want to do
1:10:55an example for you let's take a look at
1:10:57dash
1:10:57name i want you to notice it's followed
1:10:59by these characters here i just kind of
1:11:01go like this call them chihuahuas or
1:11:03something like this
1:11:05that's the technical term not many
1:11:08people knew that i
1:11:09i didn't realize that the official
1:11:11technical term now is
1:11:13um and what this is is this is the kind
1:11:16of values that you can
1:11:18give this we're getting in trouble with
1:11:20hr on that one really
1:11:22okay these things well no
1:11:25like pac-man pac-man pac-man so these
1:11:28can can be now these are the values
1:11:32that you can give to the parameter and
1:11:34i'm going to show you so let me let me
1:11:35give you a quick example here let me
1:11:37lower this uh well i'm not going to
1:11:38lower it down i'll just do it here watch
1:11:40i'm going to do git service and i'm
1:11:41going to use one of the parameters now
1:11:43parameters always begin with a dash
1:11:45so make sure you always put a dash in
1:11:47front of the parameters and now i'm
1:11:48going to put in
1:11:49a value that would be inside those
1:11:51chihuahuas and it said that the value
1:11:52type was string which means alphanumeric
1:11:55and i'm going to put in the name or
1:11:57which is a short name of a service i'm
1:11:58going to do
1:11:59bits instead of getting the entire
1:12:02service list
1:12:03this parameter now is going to allow me
1:12:05to just get the service that i want so
1:12:08here's the idea parameters can have
1:12:11these arguments on them
1:12:12and a lot of parameters can take
1:12:14multiple arguments let me show you what
1:12:16that looked like let's say
1:12:17i wanted two services notice the comma
1:12:21in between now the space is optional but
1:12:23see if you put a space there makes it
1:12:24easier to read
1:12:26now i get those two let me show you how
1:12:29that looks
1:12:29in the syntax and so let's go back here
1:12:32notice up here at dash name
1:12:34that's the parameter then we have the
1:12:36chihuahuas with the
1:12:38type of data that we can put in there
1:12:40the value type see these guys inside
1:12:43these guys and they've got to be doing
1:12:44close together because we've got
1:12:46these guys and we've got these guys
1:12:48these chihuahuas
1:12:50i just call them bankies because they're
1:12:51inside yeah so you've got chihuahuas and
1:12:54inside the chihuahuas you have these
1:12:56binkies if you see binkies in there
1:12:59that means it can take multiple values
1:13:01separated by a comma
1:13:03now i'll show you some stuff later where
1:13:05you won't see the internal binky
1:13:07and so boy there's going to be a whole
1:13:09phrase book now
1:13:10um and so can only take one value and
1:13:13this is very important for you to be
1:13:14able to know
1:13:15but here's the part where it starts to
1:13:16get a little confusing let me do
1:13:19a a little demonstration here of dash
1:13:22name
1:13:24with multiple values which i just did
1:13:25but let me show you something else
1:13:28this isn't the confusing part i'm going
1:13:29to ask jeffrey about this confusing part
1:13:31again you can do wild cards so dash name
1:13:34b star means i'm going to get all the
1:13:36services listed
1:13:37that begin with b by the way there's no
1:13:39conflict between
1:13:40wild cards and arrays or collections
1:13:43so do this do that up arrow now do oh
1:13:47now comma c star
1:13:50oh yeah yeah this is oh yeah that's a
1:13:51great point yeah great point so now i
1:13:53get both
1:13:54the ones that begin with b's and with
1:13:56c's and c that's awesome that's totally
1:13:58awesome
1:13:59so oh i closed my show window so let me
1:14:01go up here
1:14:03and open up the show window here's the
1:14:06part where i start getting kind of
1:14:07confused here and
1:14:08this this originally kind of threw me
1:14:10off as i want you guys to notice this
1:14:11guy down here
1:14:13computer name and i want you to notice
1:14:14what's around computer name
1:14:16see these brackets that surround both
1:14:19the parameter
1:14:20and the argument there so it's not the
1:14:22internal binkies inside of chihuahuas
1:14:24it's these things that surround
1:14:26either the parameter or the parameter
1:14:28and its argument
1:14:30this means you don't have to use it it's
1:14:32optional
1:14:33but wait we're not done yet and a great
1:14:36example is is
1:14:37take a look at this first syntax
1:14:40this uh syntax up here
1:14:44notice that everything has these
1:14:47around it which means that there's
1:14:49nothing
1:14:50actually required that i type in notice
1:14:53i've got them around here
1:14:54got them around here and every single
1:14:57one of them
1:14:58optional that means alls i need to do
1:15:02or all i have to do is type get service
1:15:07and it gives me a whole list in other
1:15:08words no parameters were required
1:15:11but take a look at this
1:15:16inside the syntax look at this second
1:15:18syntax
1:15:20i want you to notice look at this guy
1:15:21down here
1:15:24see how display name doesn't have these
1:15:27around it well that means if you're
1:15:29going to use display name
1:15:31you you've got to put it in and then
1:15:33you've got to give me a value for it
1:15:35now here's an example display name by
1:15:38the way
1:15:39is the long name
1:15:42so it's this really long name
1:15:45and i can get services by that display
1:15:48name but i want you to notice that
1:15:49you've got a choice dash name or
1:15:53dash display name so get service
1:15:56dash display name and now i can type in
1:16:00whatever long
1:16:01lengthy and i'm just making it up
1:16:03display name that i want to type in but
1:16:06if you're going to use display name now
1:16:07you have to use display name and the
1:16:10value that goes with it that's what gets
1:16:12you into that other syntax
1:16:14let's do something else let's do stop
1:16:17wait you didn't
1:16:17you know yeah so here's the thing yeah
1:16:19so imagine
1:16:21you wanted to get like do a get service
1:16:24b star
1:16:26just v star b oh b star
1:16:30okay so look at this the name for
1:16:32bitlocker drive encryption
1:16:34service is bdesv now remember we said oh
1:16:38well you want to create a world where
1:16:40you think about what you want you type
1:16:41it and you get it
1:16:42how many of you are thinking oh i want
1:16:44to get the bde
1:16:46svc service right like wow
1:16:49so no you want bidlocker okay so then
1:16:52you want to say okay well get service
1:16:54might display
1:16:55bit no you can't type bitlocker it's
1:16:58bitlocker
1:16:59drive encryption service so
1:17:02so remember powershell is great because
1:17:06i'm flawed i can't remember b d
1:17:09e s v c and i'm definitely not going to
1:17:12remember
1:17:12bitlocker drive encryption service and
1:17:14look even if i could
1:17:16remember it i can guarantee you i cannot
1:17:18i'm like
1:17:19incapable of typing that correctly so
1:17:23what you do is you type display name
1:17:26bit star no just bits oh just bit star
1:17:29yeah dead star
1:17:31something to do with bitlocker a doom
1:17:33and it just works
1:17:34it got us by the long name which
1:17:36actually makes more human
1:17:37sense than those little tiny short names
1:17:39see one of the things we said was
1:17:41with powershell it's like programming
1:17:43with with uh
1:17:44hand grenades versus sniper rifles you
1:17:47know
1:17:47it's just sort of just sort of like over
1:17:49there i don't know if i ever told you
1:17:50that story
1:17:52my buddy out of college i uh
1:17:55my roommate used to be in vietnam he was
1:17:57vietnam 18
1:17:58special forces and no it's actually the
1:18:01other guy i worked with he was a navy
1:18:02seal
1:18:02and the navy seals get their own weapons
1:18:05right so everybody else like you're this
1:18:06kind of guy you get this kind of weapon
1:18:08the navy seals
1:18:09like the the gun manufacturers would
1:18:11make them guns and he talked about this
1:18:12thing
1:18:13i never quite got it in focus but it's
1:18:15basically sort of like a machine gun
1:18:17shotgun a machine shotgun he said and
1:18:20the great thing about that was is
1:18:21in vietnam you hit the the jungle and
1:18:24you sort of only had to know what like
1:18:26was my problem
1:18:26over there or over there and you'd set
1:18:29up with this thing
1:18:30and he says you'd let loose with it and
1:18:32three seconds later your problem was
1:18:34gone or everything between you and your
1:18:35problem was
1:18:36gone you could focus in on your problem
1:18:38well that's the same sort of thing you
1:18:39just sort of like
1:18:40hey bit locker is something to do with
1:18:43bitlocker bit
1:18:44star star and so that's the kind of the
1:18:47model we're trying to go for
1:18:48is you know just sort of over here or
1:18:50sort of over there now there are times
1:18:52when you need to be precise
1:18:53and you can be precise and there are
1:18:55times where just sort of like over there
1:18:56is good enough and by the way
1:18:58when you need both uh you'll see how we
1:19:00deal with that so through something
1:19:01called minus
1:19:02what if and minus confirm yeah yeah yeah
1:19:04and so oh and jeffrey what i need
1:19:06you to help me with is this is the um
1:19:11this is the one that seems to throw most
1:19:13people off
1:19:14so a dash means that you have a
1:19:18parameter and if it's followed by
1:19:19chihuahuas that means you can put
1:19:21arguments on it and you get the value
1:19:23type of the argument string
1:19:24and that kind of thing and if it's got
1:19:26binkies in there you can take multiple
1:19:28arguments
1:19:29separated by a comma you see plenty of
1:19:31examples of us doing that
1:19:32and if you're surrounded by these
1:19:34brackets i you don't have to it's
1:19:36optional you don't have to do it at all
1:19:38but there's something tricky here in
1:19:40this view yeah
1:19:41let's look at this guy look at this dash
1:19:43name this guy's it
1:19:44throws everybody off so i it i don't
1:19:46have to type this in i don't type
1:19:47anything in because
1:19:48we all know that i can just run get
1:19:49service and get all of them but
1:19:52if i'm using dash name and i want to
1:19:54specify a name of a service
1:19:56like bits what is it with these little
1:19:59duders inside here yeah
1:20:00this is something we call positional
1:20:02parameters okay
1:20:03and so that means that if you just
1:20:05specify the value
1:20:07uh you don't have to specify dash name
1:20:10so
1:20:11so this makes so watch
1:20:14get service i can do this
1:20:18you might be saying i gotta type a lot
1:20:22actually you don't have to type a lot
1:20:23but here's what positional means
1:20:26if you're gonna give me a bunch of names
1:20:29of services
1:20:30you don't have to use dash name see
1:20:32works the same way which means
1:20:34so those brackets around the parameters
1:20:36simply mean you don't have to use the
1:20:38parameter but you got to give me the
1:20:39argument that's what makes it
1:20:40oh and it gets even better because now
1:20:42you can just type gsv
1:20:44oh yeah you can use the alias to even
1:20:47shorten it up even for so watch
1:20:49do you want to go ahead and do that is
1:20:51it gsv
1:20:53bits and so here's kind of a key kind of
1:20:56principle of powershell
1:20:57okay the principle is we want to have
1:20:59this very regular
1:21:01very uh self-describing surface okay
1:21:04so when it's three o'clock in the
1:21:06morning and things didn't go the way you
1:21:08wanted to
1:21:09and uh during some it upgrade and you
1:21:11bring up some script
1:21:13you want that script to be absolutely
1:21:16readable you want to know what's going
1:21:17on
1:21:18okay and so that's why powershell is
1:21:20very clear you know
1:21:21get dash service dash name et cetera so
1:21:24that when you're reading it you know
1:21:25exactly what's going on
1:21:26on the other hand when you're
1:21:28interactive
1:21:30you can type that if you want and we
1:21:31make it easier to type that with things
1:21:33like tap completion but sometimes you
1:21:35just want to go go go go
1:21:36and so we have all these uh shortcuts
1:21:39and aliases so that you can be
1:21:40very very productive as a high-speed
1:21:43advanced interactive user
1:21:45but then when you go and write scripts
1:21:47we encourage the more verbose style
1:21:50as a matter of fact let's just to
1:21:51emphasize on that a little bit further
1:21:54so when you're writing scripts this is
1:21:55the way that you're going to want to do
1:21:56it here in the top example you're going
1:21:57to want to be
1:21:58very uh explanatory of what you're doing
1:22:02but as jeffrey was saying when you're at
1:22:03the console
1:22:05free reign i mean if you can use aliases
1:22:07and shorten this up with the positional
1:22:09parameters so that you can quickly get
1:22:11things done you're going to see examples
1:22:12of that today because
1:22:13jeffrey uses an awful lot of aliases and
1:22:16i usually
1:22:17because i'm getting ready to automate it
1:22:19sometimes i just do the whole thing the
1:22:21first time through
1:22:22where i use all the parameters and all
1:22:24the arguments so you're going to see
1:22:26that contrast between
1:22:27working quickly interactively with the
1:22:29short
1:22:30you know short versions and then the
1:22:32long versions that you're going to want
1:22:33to see in a script but let me give you a
1:22:34hint and then we'll do another example
1:22:36and and then
1:22:37take a look at how to work with all of
1:22:38this um
1:22:40um have you guys been hitting the tab
1:22:42key you take your pinky
1:22:44take a pinky if you're a touch typist
1:22:47this is this is probably not
1:22:48for you but this pinky she's showing you
1:22:51the official flexing
1:22:53moves yeah yeah you want to make sure
1:22:54you stretch you want to warm it up at
1:22:55the beginning of every day
1:22:56stretch it stretch the pinky and you
1:22:58want this pinky to hover
1:23:00right over the tab key always because
1:23:02what you want to do is
1:23:03watch get s e i i'm going to start
1:23:05hitting attack key look look look look
1:23:07let's start going through the
1:23:08commandments we've got so many
1:23:09commandments now it's a lot of them to
1:23:10go through
1:23:11there we go wait a minute shift tab goes
1:23:12backwards watch dash
1:23:14i'm going to hit the tab key it'll cycle
1:23:16through the parameters for me
1:23:18this oh this is cool remember i said we
1:23:20make it easier to help type this stuff
1:23:22out that's what he's talking about and
1:23:23so
1:23:23look in just about as many keystrokes
1:23:26as doing like gsv uh bits
1:23:30just a couple of more and i can bang
1:23:32this out and get it to look
1:23:34really nice and clean so that if i'm
1:23:36going to use this in a script so the tab
1:23:37key is your friend
1:23:39use the tab you're going to see us use
1:23:40it all the time today
1:23:42let me show you another example of
1:23:43finding something as kind of a summary
1:23:45here of finding a commandlet
1:23:48and then taking a look at its syntax and
1:23:50then we're going to show you how to
1:23:51start to put commandments together on
1:23:52the pipeline so
1:23:53let's do this i have this business
1:23:56problem
1:23:57business problem time and my business
1:23:59problem is
1:24:00i need to get um
1:24:03i need some errors i need the i need the
1:24:06newest errors
1:24:08the newest five errors um out of my
1:24:11system log
1:24:11oh yeah so i need to be able to look at
1:24:13my event the log file
1:24:14yeah the log file so i'm thinking i need
1:24:16to look at my event logs i wonder if
1:24:19powershell
1:24:20has a commandlet that can help me with
1:24:23my event logs so get help
1:24:24star well let's see do you have anything
1:24:27with event logs
1:24:28oh and lo and behold there are plenty
1:24:32as a matter of fact this is a great time
1:24:33now you can take a look at the verbs
1:24:36you can just guess what what do you
1:24:37think clear event log's going to do
1:24:39would you
1:24:40clear it i i i bet it would clear it too
1:24:42you know what do you think get event log
1:24:44is going to do
1:24:46ta-da it's going to i know it seems
1:24:48ridiculous but this is the point is
1:24:50you're looking at the verbs and figuring
1:24:52out what they're going to do and it's
1:24:53not that difficult at this point
1:24:55now what we're going to do is i want to
1:24:57get an event lock now i can just try to
1:24:59run this but
1:24:59i want to take a look at the help file
1:25:01first so i'm going to do get help on get
1:25:03event log and i want to take a look at
1:25:06the syntax
1:25:07and i also if i have questions about the
1:25:09parameters i want to be able to see the
1:25:10definitions of those parameters so i'm
1:25:12going to do dash detailed right now
1:25:14and i'm going to go up here and go hey
1:25:17here's git event log
1:25:20take a look at the syntax look get event
1:25:22log look at all of these parameters see
1:25:24the dashes
1:25:26see the arguments that they can have
1:25:27whether they can have multiple values
1:25:29and if you don't know what something is
1:25:31like
1:25:32i wonder what newest means you can
1:25:34scroll down and you can take a look down
1:25:36here and the reason i'm going through
1:25:37this is
1:25:38this is what we all have end up doing is
1:25:40i don't know necessarily what all the
1:25:42parameters mean so a lot of times i go
1:25:43to the list and i
1:25:44read the list of parameters first
1:25:47just to find out what capabilities i
1:25:49have i know that seems like it may take
1:25:51a few extra minutes but it's worth it
1:25:53because i found
1:25:54that newest means i can get the newest
1:25:57entries in the log but also take a look
1:26:00at something else in this syntax
1:26:01oops where'd he go look at all of the
1:26:04things that are
1:26:05optional but i want you to notice
1:26:07something looking up here
1:26:09i want you to notice that dash log name
1:26:12isn't required but
1:26:14this guy is i want you to see what
1:26:16happens when
1:26:18something is mandatory and you try to
1:26:20run it so if i just tried to run get
1:26:22event like i want you to think about
1:26:23this if this worked just like this
1:26:25think about all of the it's going to go
1:26:27through all the logs and spit all of the
1:26:29logs out on my screen
1:26:31could that be a little performance issue
1:26:34especially if you're doing it
1:26:36to 50 machines at once that's now called
1:26:38big data
1:26:39yeah that's right big data
1:26:45so watch i'm going to strike enter and
1:26:48powershell smart enough to go hey look
1:26:51you need to know what log you want to
1:26:52look in so we're going to
1:26:54make you tell us what log so i'm going
1:26:56to say system now of course it's now
1:26:58going to give me the entire system log
1:27:00but let me just show you by using the
1:27:03help file
1:27:04looking at the examples reading the
1:27:05parameters you can start to make
1:27:07solutions
1:27:08like this get event log i know once a
1:27:11log name
1:27:11i want the log name system i also know
1:27:13that i want the newest i think you can
1:27:15tab complete that too
1:27:18i think you can now too yeah wait a
1:27:19minute let's try it didn't used to be
1:27:21able to do that let's see
1:27:23oh look is that cool that is totally
1:27:25cool
1:27:26i noticed that a lot in v3 that you can
1:27:28now tab complete on a lot of the things
1:27:29that the system has i think
1:27:31another reason you should be using v3
1:27:32yeah um yeah right that's a v3 is on
1:27:35not on v2 ism yeah so i know that by
1:27:38looking at the help file the newest will
1:27:40let me get the newest i'm just going to
1:27:41say
1:27:41three entries but here's the thing you
1:27:43guys know this in a log file there's a
1:27:45lot of that information
1:27:46stuff and i don't want that just so
1:27:48happens if you look at the help file
1:27:50you'll find that entry type error
1:27:53that's going to give me the three latest
1:27:56errors now you might be thinking to
1:27:58yourself
1:27:59well that's not you know that's cool but
1:28:01you know i had to do a lot of reading i
1:28:02could have just
1:28:03opened up you know the graphical for
1:28:05this
1:28:06oh yeah but watch this
1:28:10thing is this there's a parameter here
1:28:13called computer name
1:28:14i want the latest three errors from
1:28:18three different computers um
1:28:21here's the thing i i you need to kind of
1:28:24get from all of this you can't open the
1:28:27graphical
1:28:28fast enough more or less get that data
1:28:31that quick
1:28:33so in this one command that i figured
1:28:36out
1:28:37i can get errors from multiple computers
1:28:41on my display now it's on my display
1:28:45and we're going to fix that here in this
1:28:46next section because maybe i don't want
1:28:48it on my display
1:28:49maybe i want it i don't know in a web
1:28:52page
1:28:53or a csv or something like that but
1:28:56they missed the look show that again a
1:28:59web page
1:29:00that's why i turned it differently
1:29:03so so i've used the help file to build
1:29:07one great command
1:29:08and now we want to start doing more with
1:29:10it so
1:29:11to kind of wrap this up here i've got
1:29:13some slides in here and like i said
1:29:15everything that we've been doing is
1:29:16is in the slide deck so let me just kind
1:29:18of thumb through here the slides again
1:29:20questions you missed something crucial
1:29:22did i yeah what are you going to go back
1:29:24to that uh
1:29:25the wild card help go interactive
1:29:28all right would you which good lord here
1:29:30go to mine
1:29:33he said get help help star
1:29:36event log okay and pointed out oh look
1:29:39here you got clear you got get
1:29:41limit but look here about oh i forgot to
1:29:45talk about the about hell yeah no this
1:29:47is like one of the most important things
1:29:49it's about event logs okay
1:29:51so these are what we call conceptual
1:29:53topics okay
1:29:54so you say okay clear screen and then by
1:29:57the way here's a trick i do right so if
1:29:59i did
1:29:59clear here's thing so now i want to see
1:30:01this if i do clear screen
1:30:03and then what was it i was going to do
1:30:05oh shoot so what you do
1:30:07all right because again i'm flawed right
1:30:09now it's about
1:30:10something okay so here so what you do is
1:30:13you do clear screen
1:30:14and then semicolon semicolon is a
1:30:16statement separator that says
1:30:18do this and then do something else so
1:30:21it's a way to do two things at once then
1:30:23we say
1:30:24get let's just say help about
1:30:28event by the way tab return event logs
1:30:31so then it clears the screen
1:30:33and shows me about and so here notice it
1:30:35gives me a short description
1:30:37describes things viewing the event logs
1:30:40goes through the
1:30:41the discussion about the topic tells you
1:30:44about the commands etc and so there's
1:30:46quite a bit here and then
1:30:48clear screen if you just say help about
1:30:51underscore star yeah that's there you go
1:30:55you'll see lots of about topics i mean
1:30:58look at them
1:30:58there's a and there's just a ton of
1:31:00really good stuff here like
1:31:02wild cards hey about wild card
1:31:06about wild cards about powershell
1:31:08version four guess which one i'm using
1:31:10about the isc about wmi and there's the
1:31:13one i mentioned remember
1:31:14remember about wql yeah so so i got to
1:31:18tell you this is one of the best
1:31:19investments you can make is to go and do
1:31:22this
1:31:22help about and spend some time reading
1:31:25them i mean
1:31:25there's really great great stuff there
1:31:27yeah and i think i think the
1:31:29the important side to this is that
1:31:30there's actually two help systems the
1:31:31help
1:31:32the help will help you discover out of
1:31:34both of them
1:31:35you've got help system for the
1:31:36commandlets and then you have this about
1:31:38underscore help system which as
1:31:40jeffrey just said is a conceptual stuff
1:31:42as we go through today we're going to be
1:31:44pointing out oh yeah you need more
1:31:45information go to the about underscore
1:31:47blah blah blah blah
1:31:48oh no there's more information in it no
1:31:50there's more than that what's more than
1:31:52that oh so you don't know about category
1:31:54category yeah so get help last category
1:31:59and here here's a trick right so you say
1:32:01um
1:32:02i know that category takes a value but i
1:32:04don't know what value it is right and so
1:32:06sometimes we have to have completion
1:32:07sometimes we don't here's what i have to
1:32:09do
1:32:09i just like give a bad value and then
1:32:12often what it'll do
1:32:13is it'll tell you what categories the
1:32:15argument blah blah blah
1:32:17does not belong to the set and it tells
1:32:20you the set of things that you can type
1:32:22oh so you can get specifically for like
1:32:24the providers
1:32:26that's the key now i'll tell you here we
1:32:28we did this and set this up and we had
1:32:30quite ambitious things for the help
1:32:32subsystem and we haven't fully
1:32:33implemented all of them
1:32:35some of our partners have implemented
1:32:36some of them but we didn't like we were
1:32:38going to have
1:32:38faqs and glossary terms so so if you say
1:32:41help faq it's not there
1:32:43okay i'd like to get around to that but
1:32:45in particular
1:32:46notice here it says where it is
1:32:49provider right so what you can do is you
1:32:52can say
1:32:55by the way tab works
1:32:58and tells you oh look here are the
1:33:00various providers now we're going to
1:33:02talk about this topic
1:33:03later but if you did that and you said
1:33:06oh get help
1:33:09certificate certificate
1:33:13certificate okay
1:33:18it'll give you information about a
1:33:19provider when we get to the topic about
1:33:20providers this will make more sense
1:33:22but it's a very very rich health system
1:33:24yeah very rich help system
1:33:42[Music]
1:33:50so our third topic for the day is
1:33:52getting connected with the pipeline
1:33:54and the first thing is is um yeah we're
1:33:56going to go through all of this so
1:33:57there's the cute module overview
1:33:59but take a look at this what's the
1:34:01pipeline first of all look at the
1:34:02character here
1:34:03see this character okay this is located
1:34:06above like it says right here located
1:34:07above your enter key
1:34:09and the reason i say it like that is
1:34:11because a lot of folks don't even know
1:34:13where this character is let me give you
1:34:14an example
1:34:17so get service
1:34:21pipe what's going to happen is is get
1:34:24service is going to go out and get
1:34:26a collection of service objects they're
1:34:29technically called service controllers
1:34:30and you're going to see what all that is
1:34:32later but it's going to grab all of
1:34:34those services
1:34:36and then it's going to send them and i'm
1:34:39i'm not talking about a text
1:34:40representation
1:34:41i'm talking about the actual service
1:34:43objects themselves it's going to send
1:34:45them
1:34:45one at a time across this pipeline what
1:34:48do you want to do
1:34:50next to these services well let's narrow
1:34:53this down a little bit let's just do
1:34:55the name bits take a look it's running
1:35:00take a guess what i could do if i wanted
1:35:01to stop this service you probably
1:35:03could guess that there's a commandlet
1:35:05called stop service and you would be
1:35:07correct
1:35:07there is there's one called stop service
1:35:09and you can specify a name but
1:35:11here's the interesting thing
1:35:15i can pipe it to stop service
1:35:18if i could type it here's what's going
1:35:21to happen
1:35:22we're going to take that bit service
1:35:23we're going to send it across that
1:35:24pipeline stop service is going to grab
1:35:26hold of that
1:35:27and do exactly what it says it's going
1:35:29to do it's going to stop the service now
1:35:30we're going to talk
1:35:31a little bit later in more detail about
1:35:33how this pipeline works because it's
1:35:35crucially important in troubleshooting
1:35:37but just take a look
1:35:39well i wonder what it did well let's run
1:35:42ah i stopped it
1:35:43now i can pipe and i can even say start
1:35:46service and
1:35:46i'm going to use a pass through on here
1:35:49that will show me the results of what
1:35:50i'm doing
1:35:52and now it started again now i know
1:35:53that's a simple pipeline
1:35:55but that concept of taking something
1:35:57sending across the pipeline
1:35:59to have something else act on it is very
1:36:02important and we can continue we can
1:36:04pipe from one thing to the next thing to
1:36:06the next thing
1:36:07so as an example let's start out with a
1:36:10couple of cool things
1:36:11oh hey first of all jeffy what do you
1:36:12think i just love to ask people this oh
1:36:15don't be careful with the inner key
1:36:19what do you think jeffrey is that going
1:36:22to do what i think it's going to do
1:36:24yeah don't you want you don't want to do
1:36:25that i don't don't want to do that
1:36:27guys we we're going to show you the
1:36:29pipeline is very powerful
1:36:30it can also allow you to make silly
1:36:33mistakes
1:36:34so it's worth pointing out powershell is
1:36:37a powerful tool a powerful tool like a
1:36:40really sharp knife um if really sharp
1:36:43knife is super super useful
1:36:45probably don't want to give it to your
1:36:46kids right or or you want
1:36:48you know you want to be thoughtful about
1:36:50this stuff powershell you can do some
1:36:53damaging things and so often we you know
1:36:55give you techniques to deal with that
1:36:57but
1:36:58indeed you know don't complain if if you
1:37:00say oh well geez i
1:37:01removed all the files from my file
1:37:02system power darn
1:37:05by the way i did that actually i was i
1:37:07was i was i was giving an example of how
1:37:09to do this
1:37:10and and the guards that we have and i
1:37:12forgot to put that in and i hit carriage
1:37:14turn
1:37:14and it turns out if you kill lsass bad
1:37:17things happen
1:37:17bad things bad things especially when
1:37:19you're in front of like 700 people
1:37:21doing a demo very bad things happen
1:37:24strongly
1:37:25not recommended because i've hit the
1:37:26inter on the get service stop service
1:37:28and it's just not cool powershell
1:37:30doesn't ask you are you sure
1:37:32until later when we show you how you can
1:37:34get it to but it doesn't so
1:37:35it assumes you know what you're doing um
1:37:38let me do an
1:37:39example here of another pipeline thing
1:37:41let's talk about csvs for a second a lot
1:37:43of times
1:37:44export here's a command export csv guess
1:37:47what export
1:37:48csv is going to do it's going to take
1:37:49this information and
1:37:51export it to a csv and so i'm going to
1:37:54put in a path of c
1:37:55colon let's just call it service dot csv
1:37:58you guys know what a csv is comma
1:38:00separated file and yes
1:38:02you can change the delimiters if you
1:38:03look at the help file for export csv
1:38:05you can change the delimiters and modify
1:38:07how it works but
1:38:08let's take a look at this csv i'm going
1:38:10to open this up in notepad
1:38:12not the correct tool for looking at a
1:38:14csv
1:38:15because it's going to look at this text
1:38:17bob but i just want you to see see all
1:38:18that yep it's all comma
1:38:19comma separated but here's here's one of
1:38:21the interesting rules about powershell
1:38:23is
1:38:23if you can export it you're going to
1:38:25want to import it at some point
1:38:27you're going to want to work with that
1:38:28data again so if you can export it
1:38:32you can import the csv so import
1:38:36csv
1:38:39i forgot what i called it but not that
1:38:41there we go
1:38:42and now all that data comes back and
1:38:44it's formatted correctly and it's
1:38:46attached correctly so i can actually
1:38:47work with it now
1:38:48now these are simple examples of the
1:38:50pipeline but we're also showing you some
1:38:52some great export stuff so besides
1:38:55exporting
1:38:57like to a csv there's my favorite
1:39:02oops command line xml
1:39:05i love xml xml is greatest thing since
1:39:07the automation is sliced bread
1:39:10great example you guys used to do online
1:39:12banking years ago
1:39:14you go to the uh you buy something swipe
1:39:16your credit card
1:39:17three days later it would show up in
1:39:19your account today you swipe it when's
1:39:21it show up in your account
1:39:22just as it finishes swiping it's xml
1:39:25baby it's xml um so let's
1:39:28uh export to xml and here's what i'm
1:39:30gonna do instead of doing uh get service
1:39:34i'm gonna do get process i like that
1:39:37and i'm gonna make a little i'm going to
1:39:39pretend i'm going to do this call this
1:39:41good xml i want you to pretend something
1:39:45for a second i want you to pretend that
1:39:47i've just taken a snapshot of a
1:39:49perfectly running a perfectly good
1:39:51running machine
1:39:52runs perfectly and i've just
1:39:55snapshotted its processes now if you
1:39:58blink your eyes
1:40:00pretend for a moment that now i'm
1:40:01working on a non-perfectly running
1:40:03machine
1:40:07and what i'd like to do is i'd like to
1:40:09compare
1:40:12the good machine to the non-good machine
1:40:16yeah imagine those instead of notepad
1:40:17and calc imagine that was some malware
1:40:20yeah exactly i'm just using notepad
1:40:23now the the compare object i'm just
1:40:26giving an example of how
1:40:27the pipeline and how using commandlets
1:40:29can can
1:40:30be very useful to you so i've got a
1:40:32reference object now i want you to
1:40:33notice i'm going to use
1:40:34uh parentheses we're going to talk more
1:40:36about parentheticals but this means
1:40:38do this first and what i need to do is i
1:40:40need to import
1:40:41the good xml file that represents the
1:40:44good machine
1:40:47and then i want to compare that to
1:40:51this currently running machine now when
1:40:53you run get process
1:40:54there's a lot of information that comes
1:40:56up what i want is i just wanted to
1:40:58compare
1:40:59the names of the processes right now and
1:41:01see if there's a difference
1:41:03so what i've done is i've exported my
1:41:05process information with the pipeline
1:41:07and now i'm just going to compare it
1:41:10notice the site indicator points to the
1:41:13bad machine
1:41:14and is saying hey look calc and notepad
1:41:17are running on that
1:41:18and as opposed to what's on the good
1:41:19machine this is an example of how you're
1:41:22going to start to be able to build
1:41:23commands
1:41:24with the pipeline to do something and
1:41:26then
1:41:27use other commands to achieve your
1:41:28results imagine comparing two machines
1:41:32the software that's installed on them
1:41:33and making you want to make one machine
1:41:35look
1:41:35just like another so there's a lot of
1:41:37things that we can do with building a
1:41:39pipeline
1:41:40one last example and then we'll take a
1:41:41shortcut oh yeah you know so what jason
1:41:43just showed you
1:41:44is freakishly powerful and we're going
1:41:46to drill into it
1:41:47in in the future so what we did was we
1:41:50took a set of live
1:41:51objects and we compared them against an
1:41:54xml
1:41:54file like how do you do that and the
1:41:57answer is
1:41:58the magic of powershell and the things
1:42:00we call objects and object adapters
1:42:02and of course if you just try to compare
1:42:04these things it would say they're
1:42:05completely different so he didn't he
1:42:07said
1:42:07i just want to compare them based upon
1:42:09their name and so what you've done
1:42:12okay we've really kind of led you to is
1:42:14again you
1:42:15think about what you want to do you type
1:42:17it and the magic of powershell is able
1:42:19to take these
1:42:20incredibly complex stuff and present it
1:42:24to you in a very simple world
1:42:26so let me show you a couple other
1:42:27command line things and and jeffrey will
1:42:29be
1:42:29adding in um stuff here just so you can
1:42:31get the idea of kind of what's going on
1:42:34besides exporting out to like csvs and
1:42:37xml there's some other things you can do
1:42:39so get service
1:42:40everybody always wants to know how do i
1:42:42put something into
1:42:44just a text file well you know first of
1:42:46all you could have found
1:42:47out file by looking for get help star
1:42:50file or
1:42:51something like that which is totally
1:42:53awesome and you'll find out file out
1:42:55file has
1:42:56if you look at the help file for it
1:42:57wants you to give it a path
1:42:59and um and you give it a path to what
1:43:02you want to use as
1:43:03a for your text file so test dot
1:43:07text and you can get the content
1:43:11did i say get the content you can get
1:43:13the content from a text file
1:43:15you know i wonder if there's anything
1:43:17that could help me
1:43:18with getting content from a text
1:43:22file oh lookie get content the help
1:43:25system
1:43:26help systems your friend so you can get
1:43:28the content
1:43:30from a text file by just using get
1:43:32content
1:43:35and and i think i call that test.text
1:43:38and there's all that get service content
1:43:40that i just put in a text file but
1:43:42wait there's more you can send stuff out
1:43:45to a printer
1:43:46out to a printer out printer out
1:43:49printer so there's a set of things you
1:43:51could set it out to
1:43:52there's i wonder i wonder how we could
1:43:55find
1:43:56a list of the things that we could
1:43:59send stuff out to
1:44:02yeah no just out just start without
1:44:05start without
1:44:06yeah well but here look there's a ton of
1:44:08stuff that we can send for
1:44:10out um so again the help file
1:44:14is your friend besides sending stuff out
1:44:16there's also creative
1:44:18ways to do stuff so get service i love
1:44:21this
1:44:21this is one of my favorite things we
1:44:22also have convert to commandlets
1:44:25convert to csv now this is gonna make
1:44:28more sense later but
1:44:29well you just had an export csv yeah
1:44:32and we have a convert to csv the
1:44:34difference being for right now
1:44:36when you do an export csv you're done
1:44:39you're you're done when you do a convert
1:44:41to csv we're going to leave that stuff
1:44:43in the pipeline in case you want to
1:44:44pipeline it and do other things to it so
1:44:47the way i think about it yeah is uh
1:44:49export is convert
1:44:50coupled with output it to a file yeah i
1:44:53uh
1:44:54excellent excellent because if you do an
1:44:57export csv
1:44:58you have a mandatory where you have to
1:44:59send it to a file so think of it as
1:45:01a convert with an out file already built
1:45:05right in
1:45:05so we have the converts but i want to
1:45:07show you one of my favorite ones
1:45:10he he he
1:45:15um did i mention as a web guide uh
1:45:16anyways the uh
1:45:18and i want to pick just a couple of
1:45:19properties for this i'm going to take
1:45:21name
1:45:21and status the reason i knew that
1:45:23convert to html has a dash property
1:45:25parameter
1:45:26and it had chihuahuas that would take
1:45:29multiple arguments is because i
1:45:30looked at the help file so it's going to
1:45:32convert it to as you would expect html
1:45:35and at this point
1:45:36there it did it it's the cleanest html
1:45:38by the way
1:45:40it did exactly what i asked it to do but
1:45:42here's an example of me saying look
1:45:44i i don't want it to my screen i now
1:45:47want it in a
1:45:48file i want it out to a file so let's
1:45:50pipe it out
1:45:52file and let's call this just test.htm
1:45:56and you guys know if you haven't
1:45:58can you reduce your go down a little bit
1:46:00more oh yeah yeah yeah yeah
1:46:02yeah thanks guys for telling us about
1:46:03that in the discussion thing i want to
1:46:04lower my
1:46:05command down so that's that's picture in
1:46:07all its glory in all of its
1:46:09beautiful glory and you guys know that
1:46:11if you double click
1:46:13did i say double click yes i said double
1:46:15click on an htm it'll pop we'll see
1:46:17no more double clicking no more mouse no
1:46:19more mouse so what i'm going to do is
1:46:20just say
1:46:21c colon test htm and powershell will
1:46:25launch it up there for me do you get i
1:46:28just
1:46:28made a web page how many developers did
1:46:32that take
1:46:33and if you look at the help for
1:46:37convert to html you're going to find
1:46:40that you have a lot of options to make
1:46:43this pretty
1:46:44there's a lot of ways to make this very
1:46:46pretty with tables and all kinds of
1:46:48using style sheets and so forth so
1:46:50it pays to look at the help but this is
1:46:51a good example of piping
1:46:54from one command to another to achieve a
1:46:56certain result
1:46:58so let's take a look at what else we got
1:47:00going we got
1:47:01to the web page and you know these are
1:47:03just some examples of piping some stuff
1:47:06oh we're going to have to talk about
1:47:08stuff that kills because we almost i
1:47:10almost screwed up earlier yeah
1:47:12it's fun this is fun so let me and
1:47:14jeffrey you can help me out here with
1:47:16this one because i'm going to
1:47:17get service and i'm going to do stop
1:47:20service
1:47:22and i want to know if this works or not
1:47:24but seems kind of risky to me
1:47:26yeah what can i do when in trouble fear
1:47:30or doubt run in circles scream and shout
1:47:33so no that's what they juiced
1:47:38that's what they used to teach kids at
1:47:39boy scouts when you go on a trip
1:47:42oh so no here's the thing when you're
1:47:44ever
1:47:45so i once dealt with an admin who said
1:47:47you know every now and again
1:47:49it's late and doing something and i
1:47:50realize i'm about to hit the carriage
1:47:52return or enter key
1:47:53and i realize if i get it wrong like
1:47:55that's the end
1:47:56right i'm i'm going to be fired muffy
1:47:58and buffy are not going to go to college
1:48:03what are we doing that we create an
1:48:05environment where somebody that's the
1:48:06world that they have to live with
1:48:08and so in powershell if you ever have
1:48:11something that you're uncertain of
1:48:13you can always type minus what if like
1:48:16what if i did this what would actually
1:48:17happen
1:48:18and you would get
1:48:22[Music]
1:48:23and it tells you what it would do but it
1:48:25doesn't actually do it
1:48:26now the the best part is that it tells
1:48:30you what it would do
1:48:31but it didn't actually do it and if you
1:48:33look at my screen
1:48:34it says yep i would have stopped these
1:48:36services now
1:48:37if you're thinking to yourself that oh
1:48:39well this is a nice fast way to shut
1:48:40down my computer
1:48:41no no no no this is going to blue screen
1:48:43way before
1:48:44it gets shut down so it won't blue
1:48:46screen but it's going to stop somewhere
1:48:48around
1:48:49power shell service host somewhere in
1:48:51there muffy and buffy would not be going
1:48:52to college after this one
1:48:55so you're not going to want to do that
1:48:56but something to keep in mind we also
1:48:58besides what if and i use what if all
1:49:00the time because you know
1:49:02things can be dangerous that you're
1:49:03trying out we also have dash
1:49:06confirm and dash confirm is a what if
1:49:10with do you actually want to do this now
1:49:13i'm obviously not going to say yes to
1:49:15anything and certainly not yes to all
1:49:17so let's just i'm going to put my finger
1:49:19on the l right now so that
1:49:21nothing happens but i want you to notice
1:49:23it is showing you both what it will do
1:49:25and then asking you do you want me to do
1:49:27this so people ask all the time
1:49:29powershell doesn't ask me are you sure
1:49:30yeah because powershell's not for
1:49:31sissies but
1:49:32sometimes you need that capability
1:49:36so i'm going to hit l and please don't
1:49:39don't actually do anything yeah that'd
1:49:40be good hey can i show them something
1:49:42yeah
1:49:42okay so remember so at some level this
1:49:45isn't that interesting right get
1:49:47service pipe to stop service right
1:49:50uh what if i mean okay but who is gonna
1:49:53do that right you're just not gonna do
1:49:55that right
1:49:56but remember what i said earlier right
1:49:58about this like
1:49:59programming with hand grenades thing
1:50:01what i said was
1:50:02okay so let's see there's this bits
1:50:05thing
1:50:05and i i don't remember what the heck it
1:50:07was so what i'm gonna say is display
1:50:09name
1:50:10something to do with bits and or maybe
1:50:12it was something to do with bi
1:50:14right and then and then stop service
1:50:18service now did i get that one right now
1:50:20this is the more
1:50:21realistic thing did i get that one right
1:50:23because maybe bi star
1:50:25maps to bipp's service and maybe it
1:50:27doesn't so what you do here is you say
1:50:29what if
1:50:30and you're like yeah oh oh oh no
1:50:33good thing i didn't do that now at this
1:50:36point you could go and say okay
1:50:38why did that match oh i see biometric
1:50:41and then oh i see compatibility
1:50:43now if you wanted to you could go in
1:50:44here and try and like tweak this thing
1:50:46right and do this but instead you can
1:50:49just say no
1:50:49you know what it's close enough confirm
1:50:53and you say bitlocker yep that's the one
1:50:55i want to do it to so you you stop that
1:50:57and then this one you say no that was
1:50:59the only one so you say
1:51:01no to the rest and now i've stopped
1:51:05g s v b i oh
1:51:08oh i got the wrong one oh you know what
1:51:11i shouldn't stop that locker that was a
1:51:12bad thing yeah i think that might have
1:51:13been
1:51:16well great example of a practical use of
1:51:20that's confirmed i know that's perfect
1:51:22i'm now out of compliance with corporate
1:51:24policy there you are
1:51:25these doors might come bursting open but
1:51:28well so hopefully they will not burst
1:51:31open
1:51:32so guys this is our first introduction
1:51:34to the pipeline we're going to go much
1:51:36deeper into this pipeline but the
1:51:37concept again
1:51:38is you have a commandlet you're going to
1:51:41pipe the results of that commandlet to
1:51:43the next one so
1:51:44do this then do this then do this then
1:51:47do this
1:51:48until your needs are done and what
1:51:49you're going to notice is as we go
1:51:50through this and you get more and more
1:51:52commandlets
1:51:53you're going to see that the way you're
1:51:54thinking about the solving the problem
1:51:57is the way that you'll actually be
1:51:58building the commands in the pipeline
1:52:01now you don't have to do everything as a
1:52:03one-liner and one-liners are great we're
1:52:05going to do a lot of them in here
1:52:06but we're also going to do scripting
1:52:08where you know a one-liner is you know
1:52:10when it's when it's half the page
1:52:12you're probably a little out of control
1:52:13at that point but
1:52:15you can is the idea now
1:52:18before we go too much further into the
1:52:21pipeline
1:52:22jeffrey let's let's do this uh you know
1:52:24i've got a slide here so let me show
1:52:26everybody where we're at
1:52:28so guys again make sure you're asking
1:52:30questions all that kind of stuff and and
1:52:31for all the people out in the support
1:52:32the mvps and everybody who's
1:52:34contributing
1:52:35thank you so much for helping us out and
1:52:37answering all of these questions
1:52:39uh that are out there um let's go into
1:52:42extending the shell a little bit and
1:52:43there's i
1:52:44this is a fascinating conversation for
1:52:45me because
1:52:47i can't remember the exact number but i
1:52:48think when powershell 100 came out i
1:52:50think there's like 192 commandlets
1:52:53that's right that's all we could do was
1:52:54like 190 things yeah yeah then
1:52:56powershell v2 came out and there was 236
1:52:59well there's only 236 things
1:53:01that we could do but we need to do more
1:53:05than that
1:53:05i mean we we need something that's
1:53:08extensible so that we can do
1:53:09so how do we get more than just the core
1:53:12powershell command lines who's
1:53:13responsible for all of that kind of
1:53:15stuff
1:53:15it takes a village my friend it takes a
1:53:17village it's a village
1:53:20that's exactly the point so the
1:53:22powershell team is responsible for the
1:53:24core powershell
1:53:25environment the language etc and then
1:53:28you have plug-ins
1:53:29right or snap-ins or we now call modules
1:53:32and this is where you know like trust me
1:53:35you don't want me writing the link
1:53:36commandlets right that's not
1:53:39that doesn't end well and so we do is we
1:53:41create an
1:53:42environment where it's very easy for the
1:53:44individual feature teams to write their
1:53:46stuff and ship their stuff and that's
1:53:48why when you say
1:53:49oh well i i want to do some stuff with
1:53:52powershell
1:53:53uh where are the link commandlets well
1:53:55do you have link installed because you
1:53:56don't have link installed you're not
1:53:57going to get the link commandlets
1:53:59so the idea is that the commandlets ship
1:54:02with the thing that needs to be managed
1:54:04okay so we do this through modules also
1:54:07in the
1:54:08originally they were snap-ends right so
1:54:10snap-ins and if you've got powershell
1:54:12version one or powershell version two
1:54:14you have this thing called snap-ins it
1:54:16turns out there were a number of
1:54:18limitations with snap-ins
1:54:19the biggest you had to be administrator
1:54:21to get them installed
1:54:23and there's something else well oh you
1:54:26couldn't xcopy deploy them
1:54:28yeah and modules now modules is
1:54:31basically uh
1:54:32kind of conceptually modeled after the
1:54:34module or
1:54:35package modules of pearl and python and
1:54:38ruby
1:54:39but actually it's much richer than those
1:54:41much richer than those
1:54:42but the idea is you'll be able to
1:54:44package up your stuff and then
1:54:46x copy deploy it and then you import
1:54:48your modules
1:54:50so let's take a look first of all on
1:54:52what jeffrey is saying is and i think
1:54:54this is
1:54:55it's a you guys all of you guys have run
1:54:57the mmc before
1:54:59and you know the mmc you can file
1:55:02add remove snap in and you get a list of
1:55:05stuff here that you can add in i want
1:55:06you to notice on mine
1:55:08i happen to have some of the active
1:55:09directory snap-ins you guys know that
1:55:12in order to get those i had to install
1:55:15something and in this case i'd install
1:55:17the remote server administration tools
1:55:18to get the active directory ones
1:55:20well it's the same concept when you're
1:55:22working with powershell
1:55:24do you have the product installed well i
1:55:26have the remote server administration
1:55:28tools installed and so
1:55:30i'm going to get those modules let me
1:55:33show you powershell
1:55:35has a command called get module
1:55:38this will show you what's currently
1:55:40loaded up however
1:55:41list available will show you the modules
1:55:43that are available now i need to just
1:55:44tell you right now i
1:55:46this is very confusing in v2
1:55:49yeah yeah in v2 first of all you're not
1:55:52going to see what you're going to see on
1:55:53my screen
1:55:54in v2 you're not going to see it in
1:55:57windows 7
1:55:58either what you're seeing here is
1:56:00windows 8 running the windows 8 remote
1:56:02server administration tools and i get
1:56:04more modules than you do
1:56:06because he's cool well not because i'm
1:56:08cool because i've
1:56:10upgraded um so on i know your corporate
1:56:13standard
1:56:14you may not be doing it yet but your
1:56:16admin box
1:56:17needs to be running v3 and as you're
1:56:20going to want
1:56:20it needs to be running windows 8 okay so
1:56:23but at any rate let me just show you
1:56:26god i i'm not the guy that works for
1:56:28microsoft and i'm the one over here
1:56:30um so you can see i get this giant list
1:56:34of modules and
1:56:35notice one of the modules at the very
1:56:36top here is called active directory the
1:56:38reason i have that module
1:56:40is because i installed the remote server
1:56:41administration tools here's what that
1:56:43module contains
1:56:45commandlets commandlets that let me
1:56:47manage active directory
1:56:50and what and providers but we didn't
1:56:52provide us we don't talk about providers
1:56:53yet but yes and providers
1:56:56if you have a module with commandlets
1:56:58here's the beautiful thing about
1:56:59powershell v3
1:57:01you're going to love this when you use
1:57:02get help
1:57:04get help knows how to look through those
1:57:06modules even if they're not loaded
1:57:08so get help i want you to show me do i
1:57:10have any
1:57:11active directory commandlets
1:57:15i want you to notice that yes there's a
1:57:17lot of things with a.d in it and i could
1:57:18have refined the search better but
1:57:20that's kind of my point is i want you to
1:57:21see that
1:57:22there's a whole bunch of ad commandlets
1:57:25here you'll recognize
1:57:26ad computer as this will give me active
1:57:29directory computers
1:57:31that helps that help get help knows how
1:57:33to look into these modules
1:57:35find these commandments to show them so
1:57:37you still have complete discoverability
1:57:40and when you want help on the command
1:57:42that you found
1:57:43get help get ad computer
1:57:47it'll give you the help for it when you
1:57:50try to use the commandlet
1:57:52this is one of the biggest features for
1:57:54me personally in v3
1:57:56is when you try to use the commandlet
1:57:59and i think i may have used this one
1:58:00earlier so you may not see it flash on
1:58:02my screen but
1:58:03take a look up it just ran but let me do
1:58:07this i'm going to close my console and
1:58:09reopen it because i i want you to see
1:58:10this if you can catch it on my screen
1:58:12real quick
1:58:13let me the other way to do this is do it
1:58:15do a get module
1:58:18we'll show it yeah get module okay let's
1:58:20do that we're gonna do
1:58:22get module yeah character turn
1:58:26so these are the currently loaded
1:58:28modules right these are the currently
1:58:29loaded
1:58:30yes now do it and then and now yes thank
1:58:32you thank you so these are the currently
1:58:34loaded ones now watch what i'm going to
1:58:35do i'm going to do get
1:58:36ad computer and watch what flashes
1:58:38across my screen real quick just
1:58:40boy that was real quick i don't know if
1:58:41you caught it it actually
1:58:43dynamically loaded the module for me so
1:58:46that i had the commandments and notice
1:58:47the commandlet ran
1:58:49i didn't have to do anything special the
1:58:51reason i'm making a big deal about this
1:58:53and here i'll show you and get module
1:58:54get module now you'll see that
1:58:56it automatically loaded the active
1:58:58directory module for me
1:59:00reason i'm making a big deal about this
1:59:01in v2 your life sucks because it doesn't
1:59:04work that way
1:59:05let me tell you and i'm i'm sorry sir
1:59:07but this
1:59:08in v2 this was painful because in v2 get
1:59:12help would not find the commandments
1:59:13unless the module was
1:59:14imported yes so you had to know what the
1:59:17module was
1:59:18first then import it then you could
1:59:21discover
1:59:22see it didn't quite work they fixed all
1:59:24that with b3
1:59:25now it works just like i need it to work
1:59:28and when i run the command the module
1:59:29loads
1:59:30so i'm not loading modules unnecessarily
1:59:33and
1:59:33i'm um if i'm writing scripts that are
1:59:36using the commands it just loads what it
1:59:37needs
1:59:38and i don't have to worry about it it's
1:59:40a beautiful world
1:59:41it's a beautiful world it's a beaut you
1:59:43got any more on modules because that's
1:59:45about all i got on modules
1:59:46well you can do but would we get to this
1:59:49now
1:59:50what do what do you want to do modules
1:59:51on other machines implicit remote
1:59:53no oh no we'll do implicit oh boy we're
1:59:55going to talk about the
1:59:56we'll get to that later yeah it's so
1:59:58cool it's so cool it's so cool so let me
2:00:00show you the slides guys we've got all
2:00:01this
2:00:02so that's an after lunch thing they'll
2:00:03need like high energy
2:00:05and let me just warn you right now
2:00:06because we're only about 30 minutes or
2:00:08so away from
2:00:09taking a meal break meal break that's
2:00:11the international term for lunch
2:00:13yeah meal because we're we're taking
2:00:15lunch um is is that don't
2:00:17don't eat a lot because you don't want
2:00:19to fall asleep yeah
2:00:20after lunch absolutely it's have some
2:00:23coffee so we've got everything in the
2:00:24slides and powershell three dynamically
2:00:26uh
2:00:27loads the modules for you and you can
2:00:29you can discover all of your commands
2:00:31thank god for v3 makes this
2:00:33much easier and so uh you can work with
2:00:36your commands
2:00:37and off you go
2:00:41[Music]
2:00:55[Music]
2:01:04now's when the fun starts to begin
2:01:07before lunch i'm sorry to do this to you
2:01:09no this is good yeah this is great i
2:01:10know this is they can handle this this
2:01:12is great all right
2:01:14we're gonna we gotta talk about objects
2:01:16we're gonna talk about objects
2:01:17and what objects are and i'm gonna let
2:01:20jeffrey talk as much about objects as he
2:01:21wants to talk about
2:01:22yeah so let me just show you something
2:01:24here so so
2:01:25so we've been lying to you
2:01:31i'm leaving so here we've been saying
2:01:35get
2:01:35service services
2:01:39star okay and and what do you see right
2:01:42and what you see
2:01:43is text okay but that's not what's
2:01:46really going on
2:01:47what's really going on is when i do get
2:01:49service notice i didn't say get
2:01:51service text i just said get service so
2:01:53what i'm actually getting is
2:01:55i'm getting service objects or service
2:01:57controller objects okay
2:01:58and and the point of that now don't
2:02:00freak out when you hear the word object
2:02:02right some people hear the word object
2:02:03and they're like oh my
2:02:04god you're like i'm not a developer i'm
2:02:06not a developer no
2:02:07no my friends no no no objects
2:02:09dramatically
2:02:10simplify your life okay uh now what is
2:02:13an
2:02:14object okay let's just try to deal with
2:02:16that right simple because i'm over here
2:02:17freaking out going no no no no no
2:02:20but they're going to simplify my life
2:02:21okay i'm good so uh one of the
2:02:23uh i think it was an mvp or someone at
2:02:25tech ed did a great explanation of
2:02:27objects they said
2:02:27look an object is just a thing right
2:02:30it's a noun
2:02:31that has properties and methods so think
2:02:33about a bicycle
2:02:34right a bicycle is an object and it has
2:02:38properties it has handlebars it has
2:02:42pedals it has wheels
2:02:43okay and then there are things you can
2:02:45do to it so
2:02:47an object has things it has we call
2:02:50those
2:02:50properties it has a handlebar it has a
2:02:52wheel it has a
2:02:54um a frame and there are things it can
2:02:56do
2:02:57you can pedal you can steer and we call
2:02:59those things
2:03:00methods so objects are merely
2:03:03things that have properties and things
2:03:06you can do things too
2:03:07okay i like that so far i like that i
2:03:09like that
2:03:10so here we show this thing and what
2:03:12actually happens is i
2:03:14got a set of objects now the trick is
2:03:16and here's the magic
2:03:17is that we spew these objects out and we
2:03:20can then
2:03:21work on them and when they finally get
2:03:23to the display the display says oh i got
2:03:26an object
2:03:26what the hell am i going to do with that
2:03:28like there's no way i'm going to
2:03:30burp out this like binary stuff and
2:03:32people are going to figure it out
2:03:33so what the display does it says oh well
2:03:36now
2:03:36now i'll convert it to an object or
2:03:39convert it to text
2:03:41and the whole point about that is you
2:03:42want to delay the conversion of text
2:03:45as far as possible as long as possible
2:03:47because once you have text
2:03:49it's really hard to operate with now you
2:03:52unix guys anybody with a unix background
2:03:54you know what i'm talking about right
2:03:56because imagine now let's go back to get
2:03:57process i like get process so
2:03:59get process star ss okay
2:04:02now imagine you want to get all those
2:04:05things where
2:04:06the handles were greater than let's say
2:04:09700 let's do this
2:04:10get process okay so you see there's a
2:04:13bunch of these things and some of them
2:04:15are high so say you want to get all
2:04:16those that were greater than a thousand
2:04:18how would you do it
2:04:19well in unix if this is text gets taxed
2:04:23how do you do that well let's see you
2:04:24got to cut off one
2:04:26two three lines and then you got to go
2:04:29and you say well i'm going to cut off
2:04:30from zero to
2:04:31let's see that's one two
2:04:34three four five six
2:04:38seven seven k i gotta cut off these
2:04:40first seven characters
2:04:41and then what do you get and the answer
2:04:43is a string and so how do you do a
2:04:45string comparison that's greater than a
2:04:47thousand
2:04:48well you could thousands actually easy
2:04:49you could say well if the string
2:04:51truncate all the spaces and then if the
2:04:54length is greater than
2:04:55three right then it's greater than a
2:04:57thousand but if you wanted to do it
2:04:59greater than 900
2:05:00well then you got a sum okay so you get
2:05:02where i'm going you unix guys
2:05:04you know hats off to you i don't know
2:05:05how the heck you've been coping all
2:05:07these years
2:05:08i mean it really is we call this
2:05:09prayer-based parsing right
2:05:12please work exactly and oddly you know
2:05:15it sort of worked fine but in our world
2:05:17you don't have to do that in our world
2:05:19you have these objects okay now the
2:05:22thing is
2:05:22when i do get process i'm displaying an
2:05:25object
2:05:26each row is the object itself
2:05:29and each one of these displays here each
2:05:33one of the columns
2:05:35reflects the properties okay
2:05:38so what did i tell you i told you we're
2:05:41trying to create a world
2:05:42where you think about what you want you
2:05:45type it
2:05:45and you get it and the way that works is
2:05:48because of objects
2:05:49okay so what did i say i said i wanted
2:05:52to get
2:05:53the processes i wanted to get those
2:05:56where the handle count was greater than
2:05:595 or 900 or yeah some number so you pick
2:06:02you pick your favorite number okay
2:06:03so i want to say where the handles okay
2:06:06remember where did i get handles
2:06:09right there handles okay so where
2:06:12handles
2:06:15r greater than greater than equal
2:06:17greater than
2:06:18uh 900. and voila
2:06:22it worked why did it work because of
2:06:24objects
2:06:25objects objects are so cool now wait not
2:06:27like so this is still a little bit messy
2:06:29here right
2:06:30because these handles i mean look at
2:06:32them they're all kind of like
2:06:33all over the place right so really what
2:06:35i want to do is i want to sort them by
2:06:37now how are they going again you cut off
2:06:40three lines and you do this and again
2:06:42it's strings
2:06:42so so but no no it's an object
2:06:46so what you could do is again think
2:06:48about what you want
2:06:49type it and you get it you would say
2:06:51well i want to sort it by handles
2:06:56and then you get it okay which is
2:06:59this if you're starting to get the
2:07:01concept here this is
2:07:02starting to become totally awesome look
2:07:04at the difference of working with
2:07:05objects
2:07:06one thing that you can do to start off
2:07:09is to show that
2:07:10that these are objects is i'm just going
2:07:12to grab a service real quick
2:07:15and if you want to take a look at what
2:07:18properties and notice when i run
2:07:19just get service name bits notice that
2:07:22there
2:07:22are three what appear to be properties
2:07:25displayed about this server but you know
2:07:27what
2:07:27i i'm pretty sure there's more
2:07:30properties than just these three on a
2:07:32service
2:07:32and you know i'm not seeing any methods
2:07:34here um but jeffrey just said that
2:07:37objects have properties
2:07:38and and they have methods well there's a
2:07:41way
2:07:42to show you everything that an object
2:07:44has and it's going to become a crucial
2:07:46part to working with powershell
2:07:48so how do you find out what properties
2:07:51and methods an object has
2:07:53you pipe it to a very special command
2:07:55and i'm going to
2:07:57get member now i got to be honest with
2:07:59you get member
2:08:01we usually use the alias for this so i'm
2:08:04just going to use the alias
2:08:05pipe gm and you'll just hear me say pipe
2:08:08gm
2:08:08when you pipe something to get member it
2:08:10takes the object and it
2:08:11shows you all the meth so think of it
2:08:15this way it's kind of like if i were to
2:08:16walk in front of a mirror the mirror
2:08:18shows me things like well you're six
2:08:19foot two you're blonde you've got blue
2:08:21eyes you're built
2:08:22really well and you and you have methods
2:08:25you have methods like you
2:08:26you surf and you like karate what do you
2:08:28think of my mirror
2:08:29that's awesome i need one of those yeah
2:08:32obviously my mirror does not work well
2:08:34but
2:08:35the powershell mirror being get member
2:08:37works
2:08:38very well so let me just show you if you
2:08:40take a look here there's
2:08:41a couple of pieces of information you're
2:08:43going to want to pull out from get
2:08:44member first of all
2:08:45what kind of object it is this is going
2:08:47to become very important to us
2:08:48after lunch what kind of object is
2:08:51your screen over a little bit it's
2:08:53getting truncated a little bit oh yeah
2:08:54let me get this
2:08:56does that look better here we go so
2:09:00system dot uh service process what you
2:09:02really are interested in right now is
2:09:03this period and what comes after its
2:09:05service controller that's what kind of
2:09:07object is being sent across that
2:09:08pipeline
2:09:09and then look at this list anything with
2:09:11the word property in it i don't care if
2:09:13it has some other word in front of it or
2:09:15something anything with a property
2:09:17is a property that you can use and look
2:09:20at specifically
2:09:21like jeffrey was doing handles on get
2:09:23process i'm you know look at all these
2:09:25properties down through here
2:09:27we're going to start off working quite a
2:09:28bit with properties but you also have
2:09:30methods methods like oh look start
2:09:34and stop getservice has a method to
2:09:37start and stop a service we don't
2:09:39need a commandlet necessarily because we
2:09:41have a method
2:09:42that we could use and we'll show you how
2:09:43to do that too so get member is your
2:09:46friend to show you the truth or what an
2:09:48object actually contains
2:09:50for its properties and its methods let
2:09:52me give you an example using kind of off
2:09:54of
2:09:54jeffrey's example i'm going to do get
2:09:56service
2:09:57and here's what i want to do i want to
2:10:00just select a couple of properties
2:10:04the properties that i want to see right
2:10:05now are name and status
2:10:08we have a commandlet called select
2:10:10object
2:10:11now you usually see this as its alias of
2:10:15select let me just show you it has a
2:10:17parameter called property and you can
2:10:19tell me
2:10:20what properties you now want to see well
2:10:23if i've gone to get member and i've
2:10:24looked at the list of properties and
2:10:26i've chosen the ones that i wanted i
2:10:27just type them in i just want name
2:10:30status so i've selected those particular
2:10:33properties
2:10:34now i also want you to notice and
2:10:37jeffrey just did an example of this
2:10:39i'm going to get child item or the alias
2:10:41der is a great example
2:10:42here's a list of files out of the out of
2:10:45my c drive
2:10:46files and folders right now look at how
2:10:49it's sorting them
2:10:50sorting them by name and it's sorting
2:10:52them well looks to be alphabetically to
2:10:54me
2:10:54well i want to change the sort i'd like
2:10:56to sort them by length
2:10:58and the only thing i want displayed is
2:11:00name and length so here's what i'm going
2:11:02to do
2:11:03i'm going to do get child item
2:11:08i'm going to uh select
2:11:11that the properties i want to see are
2:11:13name and
2:11:14length and this is right off of the
2:11:16example that jeffrey was doing
2:11:17i want to sort that by the property
2:11:22length
2:11:24this pipeline and the fact that objects
2:11:27are crossing the pipeline and i can work
2:11:28with
2:11:29these properties and methods making my
2:11:31life a lot easier look at that it's it's
2:11:33folders first and then it's the files
2:11:34but you know what notice
2:11:35on my files it's small z's to big z's i
2:11:39want it big z's to smallzies in other
2:11:41words i want it descending
2:11:43so let me hit my up arrow key and the
2:11:46sort object
2:11:47has a descending so now i can change the
2:11:49sort order
2:11:50and make it descending is that kind of
2:11:52cool that's good that's that's kind of
2:11:53cool that's kind of cool
2:11:54that's kind of cool that's you know
2:11:57working with the object so
2:11:59working with objects is all about using
2:12:02get member and we've shown you that you
2:12:04can do sort
2:12:06and you can do a select and we're going
2:12:08to do these quite a bit of selecting and
2:12:10sorting
2:12:11but there's some other examples let's
2:12:12see here
2:12:14keep in mind get process
2:12:17when you need to know more about an
2:12:19object this is very important when you
2:12:20need to know more about an object
2:12:22because this afternoon we're going to
2:12:23need to know more about an object
2:12:24you pipe to gm which is get member
2:12:28you'll get
2:12:31the type of object it is which we're
2:12:32going to need this later and you get
2:12:35all of its properties and its methods
2:12:36and it if it has the word property in it
2:12:39you can use it with sword and select
2:12:41like we just showed you
2:12:42that you could use it with in fact it's
2:12:45it's kind of interesting there's all
2:12:46kinds of stuff you can do
2:12:48so back to an earlier example get event
2:12:50log
2:12:53log name system and we're going to do
2:12:55newest
2:12:57let's just do new toolboost 5 and i want
2:13:00to
2:13:01if i just run this you can see i'm
2:13:02getting all this information across here
2:13:04i'd like to take a look at the object
2:13:06itself so what i'm going to do
2:13:08is because i want to see what all the
2:13:10properties are
2:13:11i'm going to pipe it to gm wow there's a
2:13:13lot more properties out here
2:13:15than i was seeing in the original
2:13:17display time generated time written so
2:13:20you know what i think i'd like i think
2:13:21i'd like
2:13:22um event id and time generated
2:13:26and i think i would like oh
2:13:29what else would be a good property maybe
2:13:31um
2:13:33a message that would be perfect that
2:13:35would be perfect
2:13:36so i'm going to up arrow
2:13:40select the property event
2:13:44id yup comma
2:13:47and if you take a look at the help file
2:13:48you'll see that dash property takes
2:13:50multiple values so
2:13:52i can do time generated or time written
2:13:54let's do time written i think i can type
2:13:56that one
2:13:57you can hit tab version three
2:14:00version three version three
2:14:03see i just hit tab and it made my life
2:14:05much easier in typing
2:14:06so now i've selected those there we go
2:14:09and now i'd actually like to sort them
2:14:11on the on the time written
2:14:13now guys this is a vm so there's not a
2:14:16whole lot of stuff out here but you get
2:14:18the idea i'm going to sort
2:14:20on the property of okay now i'm not
2:14:22getting my tab
2:14:23time written and voila
2:14:27and if i want to sort it descending i
2:14:28can sort it descending but now
2:14:31that i'm understanding the pipeline i
2:14:33know how to find
2:14:34the properties that i want not just the
2:14:36ones that i saw on the display but
2:14:38i can find all of the properties and
2:14:40then just select the ones i want and
2:14:42sort the ones i want
2:14:44now that i have what i want well i don't
2:14:46want it on the screen
2:14:48i want it converted to an html file and
2:14:54i just love this sql
2:14:58errors dot htm and actually this will
2:15:01take a unc
2:15:02out file will take a unc so you just
2:15:04throw it to a web server
2:15:06dimension as a web guy that's uh anyways
2:15:08uh and so here's the deal
2:15:10so i've got this this this great
2:15:13one-liner right now
2:15:14that's grabbing the errors and right now
2:15:16it's from the local machine but i can
2:15:18throw a dash computer we get it from
2:15:19multiple machines
2:15:20it's selecting out just the information
2:15:22i want it's sorting it the way that i
2:15:23want it's stuffing it into a web file
2:15:26i can now tell the other admins hey when
2:15:28you get up in the morning
2:15:29go check the web page and if there's any
2:15:31errors in there
2:15:33start trying to fix them because as
2:15:35you're going to see later
2:15:36we're going to automate this and
2:15:38schedule this
2:15:39and make this go for us so i don't have
2:15:41to type it again so once i figured it
2:15:43out
2:15:43but you can see it's like figuring out a
2:15:45puzzle and just to show you that it
2:15:46actually worked
2:15:47what did i call it error hdm
2:15:53there's a woohoo even from the guys in
2:15:55the back so you must
2:15:56it's all good you must be a little
2:15:58impressed with that what else should we
2:16:00show them with
2:16:00subjects right now okay so here's the
2:16:02thing about objects i mentioned to you
2:16:03that
2:16:04objects dramatically simplify your life
2:16:06it's true
2:16:07okay so here's the thing what we've been
2:16:09showing you
2:16:10are net objects now these.net objects
2:16:12are actually
2:16:13very well behaved objects but you know
2:16:15the world
2:16:16the world is a messy place and not
2:16:18everybody has your best interests in
2:16:20mind
2:16:21and so in particular there's a lot of
2:16:23people who use net in a way
2:16:25that is good for them but not good for
2:16:27you
2:16:28okay and in particular what they do is
2:16:29they hide things
2:16:31and this is ubiquitous right this
2:16:32happens in wmi it happens in adsi
2:16:35active directory happens in xml etc
2:16:38now powershell we got exactly one
2:16:41customer that's
2:16:41you okay so i am focused in on making
2:16:44your life
2:16:45great okay and so what we do is we go
2:16:47and we say
2:16:48these guys didn't help you we'll help
2:16:50you right we will take their stuff
2:16:52and we'll adapt it for your needs now
2:16:55let me just give you an example of this
2:16:56okay
2:16:57so here i have i've got this xml file
2:17:01okay so r d dot j so let's see if i can
2:17:05actually bring that up
2:17:07so can i do this open can do an open
2:17:11powershell.org yeah we'll talk about
2:17:13that that's cool we are but
2:17:14let's see can i do an open okay yeah so
2:17:16i want to say c
2:17:18uh jumpstart
2:17:21slash r and here's my xml
2:17:25and it is the tragedy of romeo and
2:17:29juliet
2:17:30oh it's beautiful and look here so you
2:17:32got personas
2:17:34you got you got ax and in the acts
2:17:37you've got
2:17:38speeches and you got oops sorry and you
2:17:40got and you got speakers and you got
2:17:42lines okay now by the way this next
2:17:44thing i'm going to show you
2:17:45i'm going to show you the way to do it
2:17:47in powershell version
2:17:493. okay in powershell version 2 you can
2:17:51do it but it's
2:17:52harder and and the stuff i'm going to
2:17:54show you requires version three
2:17:56okay so we have this thing we'll call it
2:17:58dollar sign it's also an
2:18:00x um and what we're going to do is we're
2:18:03going to
2:18:04cap that file a cat is the same as get
2:18:06content but
2:18:07remember i said i'm an old linux guy old
2:18:10unix guy
2:18:10so i'm going to say cat r d and what i'm
2:18:13going to do here
2:18:15is i'm going to cast it something called
2:18:17casting it
2:18:18as xml so i'm going to copy this file
2:18:21and i'm going to cast it as xml and now
2:18:24i have this
2:18:25object dollar sign x which contains
2:18:29the xml okay now this is really xml
2:18:32right so
2:18:32if i did the way you can tell that is
2:18:35you can type get type
2:18:37and you can see it's an xml document
2:18:39okay so this is xml
2:18:41now have you ever worked with xml not in
2:18:44its raw form
2:18:46it's hideous it is like kicking a dead
2:18:49whale along the beach you know
2:18:50all sorts of effort and it seems little
2:18:53result
2:18:54nothing ever ever happens it's just
2:18:55hideous but not in powershell right so
2:18:57in powershell
2:18:58again i map this hideous world to your
2:19:00world right so remember what does this
2:19:02thing look like
2:19:05blah like right okay well here when i
2:19:07said oh i see dallas on x dot play
2:19:10dot play okay oh look at that
2:19:14so then here are the the x
2:19:18oh look at that and so i could say well
2:19:20hey give me act 0
2:19:22and give me the scene and hear all the
2:19:26scenes
2:19:27and then i can say hey scene 0
2:19:30give me the speech and there are all the
2:19:34speeches
2:19:35okay okay look at that is that cool or
2:19:38what now wait wait wait it gets better
2:19:39here if i get rid of this index so
2:19:42remember
2:19:43it gave me a set of of things and i
2:19:46selected the first one
2:19:47so now what i'm gonna do and because
2:19:48powershell version three
2:19:50i can go and i say hey i want all the
2:19:52scenes and i want
2:19:53all the acts and it gives you to them
2:19:57all
2:19:58okay now if you remember let's let me
2:19:59just do something to select
2:20:01first one okay so
2:20:04now what i can do is i can say hey i
2:20:06would like to group them
2:20:08by the speaker and i would like to sort
2:20:11them
2:20:12by count and if you're gonna
2:20:15if you're in theater you definitely want
2:20:17to be romeo
2:20:19right right that's not the third
2:20:20musician because the third musician has
2:20:22exactly one speech
2:20:24whereas romeo has 163. now let's just
2:20:28think about this a second
2:20:30let's just think about this a second so
2:20:32here i have this xml and the point is
2:20:34that there's a bunch of xml in the world
2:20:36right
2:20:36like you didn't ask for it but somebody
2:20:38decided hey i'm going to give you some
2:20:40xml
2:20:41thank you thank you so much but and so
2:20:44it's like
2:20:44uh like what what what what what this
2:20:47hideous horrible world and again if
2:20:49you've ever dealt with xml you know
2:20:51exactly what i'm
2:20:52talking about but what we do is we're
2:20:54able to
2:20:55by the way by the way if i wanted to get
2:20:57the history of things that i
2:20:59typed you would type get
2:21:02history okay
2:21:05and so here are the things that i typed
2:21:07so what i did
2:21:09was i
2:21:12[Music]
2:21:14okay so first was i got the content of
2:21:17that file
2:21:17and i cast it to xml here somewhere
2:21:21somewhere somewhere here
2:21:24right and then i showed you that it was
2:21:27an xml document
2:21:28here and then you're able to ask for the
2:21:30play
2:21:31we were able to see that it had an act i
2:21:33drilled into act
2:21:34one i saw that it had scenes i drilled
2:21:37into scene one
2:21:38and saw that it had speeches and i got
2:21:40that speech and then
2:21:41i removed all those and i got all the
2:21:43speeches
2:21:45and then i selected the first one to
2:21:48find out what the properties of that
2:21:49speech were
2:21:50i saw that it had a speaker and so i
2:21:53grouped it by speaker and sorted it by
2:21:54count
2:21:55and it's that simple and what's really
2:21:58amazing about this is is notice that
2:22:00we're utilizing the pipeline
2:22:02and we're building these results as we
2:22:04move along we're utilizing the objects
2:22:06because it's an
2:22:06object-based pipeline and so even
2:22:10you know what he's right if you're in
2:22:11version two we didn't use the pipeline
2:22:13but that is actually the point
2:22:14in version two you would have had to use
2:22:16the pipeline back from
2:22:18from this when we did this right
2:22:21to get everything what you would have
2:22:23had to have done was something like
2:22:25because we fixed it right you would have
2:22:27done something like
2:22:28let's see i think it was this you would
2:22:30have to say
2:22:32through select minus expand
2:22:39scene no
2:22:42i think i even got that wrong through
2:22:44select minus expand
2:22:47speech and i did get this wrong anyway
2:22:49so a bunch of pipelines very very
2:22:51powerful stuff and in version three
2:22:53we simplified it with the dot syntax and
2:22:56the dot syntax you're going to see quite
2:22:57a bit today as we start utilizing it but
2:22:59combining that along with the pipeline
2:23:02really makes it very powerful now a
2:23:04couple of other things that jeffrey was
2:23:05showing you that i want to highlight and
2:23:07we're going to need this information for
2:23:09this afternoon
2:23:10so along with working with objects
2:23:12jeffrey also showed
2:23:13you showed you a filter so let me give
2:23:16you an example get
2:23:17service we have a commandlet called
2:23:20where
2:23:20object now where object is a way for you
2:23:23to filter out only the data that you
2:23:25want to see
2:23:26usually you'll see it abbreviated down
2:23:28to where it's
2:23:29that's using the alias that way now
2:23:32there is a parameter called
2:23:34filter script that has a couple of
2:23:37squigglies
2:23:39squigglies whatever happens in the
2:23:42squigglies
2:23:43is your filter now i'm going to show you
2:23:44a couple of ways to write a filter
2:23:46because this is what you're going to see
2:23:47on the internet
2:23:48first of all almost nobody uses the
2:23:51parameter name
2:23:52filter script so it's the squigglies i
2:23:55want you to see something
2:23:56this is a special symbol now we're going
2:23:58to talk about variables later but the
2:23:59dollar
2:24:00sign is a special indicator for you and
2:24:02in this case
2:24:03dollar sign underscore means
2:24:06the current object crossing the pipeline
2:24:09now
2:24:10notice i've got get service that's got a
2:24:12whole bunch of objects we're going to
2:24:13send
2:24:14one at a time across the pipeline i want
2:24:16to grab hold of that for a second
2:24:17because i want to do something to it
2:24:20it's stored in dollar sign underscore
2:24:22now in v3 there's another way that we
2:24:26can show you to do this but hang on a
2:24:27sec let me show you
2:24:28i want to look at the property
2:24:32status and if it's equal to
2:24:36running as a filter i want you to think
2:24:38about this
2:24:39this is going to filter out only the
2:24:41things that equal to running now i know
2:24:44you might be saying
2:24:45what the devil is this eq over here why
2:24:47isn't it
2:24:48why isn't it equals why isn't it equals
2:24:52yeah so here's the thing bruce payette
2:24:53superstar rockstar wrote this great book
2:24:55powershell in action
2:24:56where he goes and describes all the
2:24:58reasons why we made the language choices
2:25:01so if you ever get to the point where
2:25:02you're asking deep questions like this
2:25:05bruce's book powershell in action is the
2:25:07book to answer it
2:25:08here's the thing we struggled with this
2:25:10one over and over and over again
2:25:11honestly
2:25:12as as we started and designed the
2:25:14language in the system
2:25:15we struggled with saying hey we want to
2:25:17be interactive
2:25:19and programmatic see in in linux where
2:25:21we had all
2:25:22unix where we had come from you have
2:25:24these big separations right
2:25:26you start off with one tool and then
2:25:29that tool fails you and so you got to
2:25:30throw everything away and you got to
2:25:32pick up another tool right
2:25:33try and write it in the shell script
2:25:34it's not powerful enough so you throw
2:25:36that away and start writing in
2:25:37awk and grep and said that's not
2:25:39powerful enough so you throw that away
2:25:41and then you use it in pearl
2:25:42and that's powerful enough but it's too
2:25:44slow so then you throw it away and you
2:25:46pick up
2:25:47and write it in c right so that's my
2:25:49joke right unix is a
2:25:51sequence of failed tools what we wanted
2:25:53to do is to have one tool
2:25:55that would work whether you wanted to do
2:25:57it interactively
2:25:59or you want to do this rich systems
2:26:01programming level
2:26:02and it turns out that's hard never been
2:26:04done before never been done before
2:26:07and we did it and honestly we just
2:26:09struggled with this
2:26:10hey turns out there's a reason why
2:26:12interactive shells have an interac have
2:26:14a syntax the way they do
2:26:15there's a reason why programming
2:26:17languages have the language
2:26:19the syntax that they do and so we
2:26:21struggled with this
2:26:22and uh and so we were able to finally
2:26:24get this nice match between those two
2:26:27and part of the ramification of that was
2:26:29or part one of the ramifications of that
2:26:31was
2:26:32that we needed to use uh well by the way
2:26:34when we chose a programming language
2:26:35we chose the c style so there's c c
2:26:39plus plus c sharp so we chose that style
2:26:42of things
2:26:42that's why you have squiggle brackets
2:26:44versus begin and end or
2:26:46do and done or do and od
2:26:49always confuse me yeah exactly i like
2:26:50the terse kind of language exactly
2:26:52um and programmers do too and by going
2:26:54guess who's going to write most of your
2:26:56commandlets it's the programmers so you
2:26:58want a world that's friendly to them
2:27:00so um so that's what we did and it
2:27:02turned out that uh
2:27:03from the grammar from the parser uh if
2:27:06you had equals there uh it got ambiguous
2:27:08and we tried and tried to try it and you
2:27:10couldn't resolve that one thing
2:27:12and so that's why we have dash eq and
2:27:14let me show you guys
2:27:16it so let me i'll show this to you a
2:27:18couple of ways dash eq means equals
2:27:21and so as you can see i'm just getting
2:27:22the services that are
2:27:24i filtered out the ones that are stopped
2:27:26just the ones that are equal
2:27:27but here's the important thing you know
2:27:30these are redirect characters
2:27:32like file redirect at a in a shell in a
2:27:35console you can't use them so
2:27:37they created and you can find these by
2:27:39doing get help
2:27:40they're comparison operators so you can
2:27:43either do it by
2:27:44looking for comparison you'll find the
2:27:45help file for it which is about
2:27:47underscore comparison operators that
2:27:49lists all of these and you're going to
2:27:51see a lot of them in here
2:27:53or to see all the operators get help
2:27:56on operators because
2:27:59this you're going to see us use these
2:28:01you've got arithmetic assignment
2:28:03comparison operators
2:28:04let me just show you a couple of quick
2:28:06examples with this
2:28:08on this on this filter
2:28:11so i've got status equals running let me
2:28:14show you the v3 way to write this now
2:28:16it's important that you get used to
2:28:17seeing it as dollar sign underscore
2:28:19because you can see it on the internet
2:28:20this way
2:28:22and guys like me still use it that way
2:28:23but there's a new way to write this
2:28:27called ps item
2:28:30which makes a little bit more sense to a
2:28:33lot of folks that this is current
2:28:34holding the current item crossing that
2:28:36pipeline so
2:28:38get used to seeing it it works the same
2:28:39way as dollar sign underscore as you can
2:28:41see it'll come across
2:28:44you're going to notice that i'm probably
2:28:45going to use dollar sign underscore
2:28:46because that's
2:28:47just what i'm used to using but ps item
2:28:49works but we can extend this filter even
2:28:52further i want it that it is
2:28:54equal to running and
2:28:58dollar sign underscore and the name
2:29:01is like and when you use like
2:29:04now you can use wildcard so i want it
2:29:06like
2:29:09beast b star and i think i have some
2:29:11services that ah
2:29:13so this filter now lets me filter down
2:29:16data now
2:29:17i need you to think about something i'm
2:29:18going to do some pseudo code somebody's
2:29:20going to yell at me when i do this
2:29:22the pseudo code means it's not really
2:29:24doing anything so get stuff
2:29:28sort then where
2:29:33i just want some stuff
2:29:36and then out to a file now i i let me
2:29:39write this another way get stuff
2:29:43by the way don't try that coming out it
2:29:44doesn't work
2:29:47where which i can't spell some stuff
2:29:52sort and then out file which do you
2:29:55think is going to be the best
2:29:58performing way to write this if you
2:30:01think about it think about what's
2:30:02actually happening here i'm getting
2:30:03stuff
2:30:04and then in the first one i am sorting
2:30:06it i'm sorting all of it
2:30:10it's all sorted and then i'm handing it
2:30:12to a filter that goes yeah but i just
2:30:13wanted this
2:30:14throw the rest of it away thanks for all
2:30:16your hard work have a nice day
2:30:18as opposed to the second one which is
2:30:20get stuff well i just want this
2:30:22uh-huh and now sort it done
2:30:25so it does matter where you filter and
2:30:28where you sort refer to this
2:30:29as you filter as far left
2:30:33as you possibly can and you can see
2:30:35examples today where
2:30:37the where object may not be the filter
2:30:40that's furthest left as a matter of fact
2:30:41you see some cool examples today where
2:30:44you want to keep in mind filters far
2:30:45left and sometimes that's with the
2:30:46commandlet that's starting the process
2:30:49so um you know jeffrey i think we're at
2:30:51about
2:30:52meal time yeah you know so by the way so
2:30:54this where
2:30:55command is someone you're going to want
2:30:56to spend some time with
2:30:58that is one of the most powerful things
2:31:00like on the
2:31:01face of the planet you guys are going to
2:31:03have questions after this now i'm going
2:31:05to give you some references to go to as
2:31:07a matter of fact
2:31:07don's got a great book out there that
2:31:10you're really going to want to take a
2:31:11look at and i'm going to mention a
2:31:12little bit later on
2:31:13but when you have questions when you
2:31:15have things that um you are burning
2:31:17desires for powershell
2:31:19i have a place for you to go and i and
2:31:20since don is here let me just show it to
2:31:22you if i can figure out how to work
2:31:25windows here here we go i'm so used to
2:31:28the powershell stuff i forget the
2:31:30so there's this place called
2:31:33powershell.org.org
2:31:35and look this is a centralized place for
2:31:37you to find a ton of resources but one
2:31:39of the most important things out there
2:31:41is when you go out here you'll see the
2:31:43forums you can go out there and you can
2:31:44ask
2:31:45questions and you can get answers and a
2:31:47lot of mvps and a lot of super gurus are
2:31:49out there
2:31:49and it'd be even be great if someday you
2:31:52decide to help answer some questions but
2:31:54we've got forums we've got free e-books
2:31:56out there to help you with some of the
2:31:58specialized topics that we're going to
2:31:59be getting into today
2:32:00free powershell people's favorite word
2:32:03in the world
2:32:04free also i want to point out that we've
2:32:08got
2:32:08articles um there is a powershell summit
2:32:11so there's information on the summit we
2:32:12got a new summit coming up and tickets
2:32:14are going to go on sale and
2:32:16i'm not trying to be a sales guy or
2:32:17anything just letting you know and also
2:32:19one of the the podcast uh the
2:32:21powerscripting podcast
2:32:23it has a ton of information especially
2:32:25over the last five years
2:32:27of powershell and the power scripting
2:32:28podcast is out there and an entire
2:32:31script repository so go to
2:32:32powershell.org
2:32:33and ask questions after this event we'll
2:32:36be happy to help you out and don's
2:32:38the guy in charge of this and one of the
2:32:40people responsible for this so
2:32:42thanks don glad you're helping us out
2:32:44today um before we get started into
2:32:47uh chapter six there were some things
2:32:49that we were noticing in chat
2:32:51that we'd like to kind of talk about in
2:32:52the next exactly yeah so one of the
2:32:54questions had come up around case
2:32:56sensitivity
2:32:57and again whatever you yeah so whenever
2:33:00you wonder hey
2:33:01how does powershell do things think hey
2:33:03what would somebody who's severely
2:33:05flawed due
2:33:06right and of course that's that's your
2:33:09best predictor
2:33:10and so we try and be as case insensitive
2:33:13as possible right
2:33:14so wherever we have the opportunity we
2:33:17make things case insensitive
2:33:18there are however uh certain you know
2:33:21powershell commandlets you know other
2:33:24teams that require case sensitivity if
2:33:26that ever happens
2:33:28uh it'll be highlighted in the
2:33:29documentation but if it's not
2:33:30highlighted in the documentation
2:33:33you can assume case insensitivity that's
2:33:35what my wife says she says you
2:33:36you're very case insensitive i said no
2:33:38i'm very case sensitive very case
2:33:39sensitive and she says no
2:33:40very case insensitive very case and then
2:33:42i have to show her comparison operators
2:33:44where you can
2:33:45specify but yeah no i'm very sensitive
2:33:48anyways that doesn't
2:33:49anyways that almost worked it almost
2:33:51worked so back to you though you wanted
2:33:53to do some more stuff on wednesday yeah
2:33:54i want to party on wear okay so
2:33:56so here's the thing with wear right so
2:33:58originally we uh uh tried to design
2:34:00this where right so let's refresh our
2:34:02memory so we had we have
2:34:04get process right that's too many things
2:34:08and so then what we said was we want to
2:34:10filter this and so we pipe this to where
2:34:13right and we have the squiggle brackets
2:34:15now originally the way this worked was
2:34:18um we hired we hired some smart guys and
2:34:22we said hey
2:34:22we need sql against objects against
2:34:26live.net objects and they said uh-huh
2:34:30i said go at it my friend this will be
2:34:32straightforward
2:34:33and like three months later they came
2:34:35back and it was like and
2:34:37they had only done a small subset and
2:34:39the syntax was wonky
2:34:41and it's just clear oh that's why
2:34:44sql has like a couple hundred guys
2:34:46working on this turns out it's a
2:34:48hard problem and so we
2:34:51we took a different approach and what we
2:34:52did was we threw all that code away like
2:34:54three months ago just threw it away
2:34:56and literally literally we replaced it
2:34:59with
2:35:00three lines code three lines of code and
2:35:03and here's the kicker does that mean we
2:35:04can replace all the sql guys now too
2:35:06and it's far more powerful than sql
2:35:09basically three lines of code far more
2:35:11powerful than sql i'm going to prove it
2:35:13to you that's pretty bold right
2:35:14so here's here are the three lines of
2:35:16code okay so
2:35:18where basically takes each object that
2:35:21comes in the pipeline
2:35:22it assigns it to a variable step number
2:35:25one assign it to a variable
2:35:26dollar sign under bar now it's dollar
2:35:28sign under bar and dollar sign ps
2:35:30item we assign it to a variable the
2:35:33second
2:35:34is we evaluate the code within the
2:35:36squiggle brackets
2:35:37we run the code and three
2:35:41if the code returns true
2:35:45we pass the object on and if it doesn't
2:35:49we throw it away okay so it's that
2:35:51simple it's truman's code
2:35:53okay so now notice so that's why you're
2:35:56able to do things like
2:35:57hey um uh handles
2:36:01greater than 1000 1000
2:36:04okay so we grab the current object as
2:36:07you notice here the first object here is
2:36:10oh let's see
2:36:11this thing and its handles is 82.
2:36:14so we take this object which is the row
2:36:17we assign it to dollar sign under bar
2:36:20and then we
2:36:20evaluate this hey is are the handles
2:36:23greater than 1000. the answer is
2:36:25false so you're going to see that object
2:36:27doesn't get passed on
2:36:29if ever it's true we then pass on the
2:36:32object
2:36:32as it is and you see
2:36:36that all the things are greater than
2:36:37hundred now remember the algorithm
2:36:40it's important to memorize the algorithm
2:36:42there are very few things that you
2:36:43memorize in powershell
2:36:44this is one of them assign the object to
2:36:47dallas and underbar
2:36:48evaluate the code if the code evaluates
2:36:51to true
2:36:52pass the object on if it evaluates to
2:36:54false don't do that okay now
2:36:58notice i never said that you had to use
2:36:59the object in the expression
2:37:01right so what's that mean so i could
2:37:04have said
2:37:05now here i'm going to limit this right
2:37:06i'm going to say star ss
2:37:08okay so we're going to do a subset
2:37:09because it makes it a little easier
2:37:11i can say where
2:37:14dollar sign falls notice i didn't use
2:37:17dollar sign under bar
2:37:19nothing passed on because it always
2:37:21evaluates to false
2:37:22notice i can say dollar sign true
2:37:26and it always succeeds okay so what i'm
2:37:28really talking about so that's literally
2:37:30how it works this isn't a joke that's
2:37:32literally how it works now the point is
2:37:34these are not very useful
2:37:36and this is useful but the thing i want
2:37:38to point out here is that you just run
2:37:40the code the code can do
2:37:41anything in this example it's a simple
2:37:44expression
2:37:45but you could have put a very complex
2:37:47expression you could have put
2:37:49a script you could have put 10 pages
2:37:51worth of code here
2:37:52you know calling up your mother to ask
2:37:54her opinion on things looking things up
2:37:56in active directory checking things in
2:37:58sql you can do anything you want
2:38:00at the end it has to evaluate to true or
2:38:01evaluate to false and that's how it
2:38:02works
2:38:03so it is incredibly powerful now there's
2:38:05one other thing i want to say about
2:38:06where
2:38:07and that is a lot of people who begin
2:38:10with powershell look at these squiggle
2:38:11brackets and they said
2:38:12ah you know it's like mouse and so we
2:38:16have
2:38:16a very simplified version of wear now
2:38:19this
2:38:20isn't as rich as this wear you use with
2:38:22the squiggle brackets you can do
2:38:24anything
2:38:24the simplified wear you can do very
2:38:26subset of things you can do
2:38:28things where a property operator value
2:38:31so what you do and you don't have to
2:38:33have the squiggle brackets so there you
2:38:34go there's a deal
2:38:35and you don't have dollar sign under bar
2:38:38right so you get rid of that
2:38:39and you can just say where handles
2:38:42greater than
2:38:431000 and voila it works
2:38:47and i think for a lot of admins just
2:38:48getting started especially with
2:38:49filtering because filtering is going to
2:38:51be one of the most important things that
2:38:52you do
2:38:53this simplified syntax can be really
2:38:55helpful at first until you get more
2:38:57used to the squiggly brackets now like
2:39:00jeffrey said though
2:39:01there are limitations there as soon as
2:39:02you want to start doing
2:39:04multiple criteria and as soon as you
2:39:05wanted to call up your mother and check
2:39:07with her first
2:39:08that's going to require the squiggly
2:39:10brackets but i really like the
2:39:11simplified
2:39:12yeah can i tell you i use this thing all
2:39:13the time the simplified one
2:39:15yeah so matter of fact when we look at
2:39:17doing um some remoting stuff with
2:39:18software and that i'll
2:39:19i'll just do where installed yeah
2:39:21exactly yeah make it real short and
2:39:23sweet so
2:39:24it's going to get really cool guys
2:39:27that was awesome yeah okay
2:39:30let's get serious for a moment no maybe
2:39:33you ought to keep us both on screen
2:39:34because we both have to have this
2:39:36serious look on our face
2:39:39we're going to go into the pipeline now
2:39:41and but deeper
2:39:43deep deeper deeper you were committing
2:39:45all sorts h violated hr violations
2:39:47today you were just like it was
2:39:50inappropriate
2:39:51whose is a pacman no inappropriate
2:39:54so here's the deal what we're going to
2:39:56show you is something that is very
2:39:58advanced
2:39:59and you you need to know this you you
2:40:02need to know this but
2:40:03what's going to happen is that you're
2:40:04going to see the concept here and it's
2:40:06going to happen really quick
2:40:07and then you're going to need to
2:40:08practice this and you're going to have
2:40:09problems practicing this so i'm going to
2:40:11give you a couple of references
2:40:12right now before we get started first of
2:40:15all you're going to want
2:40:16chapter 9 out of don jones's book
2:40:19lunches
2:40:20uh uh sorry powershell in a month of
2:40:23lunches yes learn windows powershell in
2:40:25a month of lunches
2:40:27you chapter nine you're going to want
2:40:29that chapter and it'll take you through
2:40:31everything that we're gonna do and you
2:40:33will get a chance to try it now let me
2:40:35tell you how important this was
2:40:36i was sitting if you guys have been to a
2:40:37conference before i'm sure you have been
2:40:40i was sitting in a conference and you
2:40:41know they they have the
2:40:43the con you know like tech ed i mean
2:40:45they're enormous
2:40:46they put speaker they put the speaker
2:40:48they put the rooms over there and rooms
2:40:50over here and a football field
2:40:51in the middle now that's where all the
2:40:54sponsors go but
2:40:55there's this there's this giant football
2:40:57field and they don't put a lot of seats
2:40:58in there
2:40:59so you see all these people sitting up
2:41:00against the wall and working on stuff
2:41:03well i was sitting up against the wall
2:41:05working on a problem
2:41:06with getting two commandlets to work
2:41:08together in exchange and i couldn't get
2:41:10it to work
2:41:10together and i said to myself i said
2:41:15it it's it's a problem with the guys
2:41:18that wrote the commandlets it's a
2:41:19problem with powershell it just doesn't
2:41:21work i'll just
2:41:22i just can't solve that problem and not
2:41:24but a few moments later
2:41:26you and then shortly there after that
2:41:28don jones
2:41:30you taught me how to figure out how the
2:41:32pipeline works
2:41:33and suddenly by with this knowledge
2:41:36suddenly
2:41:37i could get that solution to work and i
2:41:39guess what the moral of the story is
2:41:41is that as soon as you understand this
2:41:43the answer is
2:41:44you can always get it to work so never
2:41:47give up
2:41:48it's just it's a little tricky at first
2:41:50yeah this is one of those things my i
2:41:52used to have a physics professor who
2:41:53would say
2:41:54this problem is simple once solved so
2:41:58we're gonna help you solve it when you
2:42:00first look at it you're like what the
2:42:01heck what the heck
2:42:02and then at some point there'll be this
2:42:04moment of clarity and that's just super
2:42:06super simple it really is
2:42:23[Music]
2:42:32here we go let me start you out with a
2:42:33concept and jeffrey and i are going to
2:42:35work through this we're going to talk
2:42:36about how the pipeline works
2:42:38and how things when objects get passed
2:42:41how does the receiving commandlet know
2:42:43what to do with them
2:42:44if anything at all i i'm not a good guy
2:42:47with sports analogies
2:42:48because i don't know anything about
2:42:49sports but as i understand it
2:42:51there's this thing with the small white
2:42:53balls where they have catcher's mitts
2:42:55so you know the sending command that's
2:42:58going to send some baseballs and we have
2:42:59to see what catcher's mitts they get
2:43:01caught on the receiving commandment
2:43:03you'll see what i mean we have a process
2:43:05of by value and by property name and
2:43:08if those don't work we have a last line
2:43:11of resorts so
2:43:12i'm just going to first of all point out
2:43:14that all of this is in the slides but
2:43:15i'm not going to use the slides
2:43:17so here we go let's get rid of the
2:43:19slides
2:43:21let's start with an idea get service if
2:43:24i can spell it
2:43:26stop service guys we showed you this
2:43:28earlier and you
2:43:29we did dash what if you know that it's
2:43:31going to work
2:43:33but the question that i have in my head
2:43:35is why well here's what's happening
2:43:38getservice has is getting a bunch of
2:43:41services a bunch of objects and we're
2:43:42going to send one object at a time
2:43:43across the pipeline
2:43:45my question is is the receiving command
2:43:47which in this case is stop service
2:43:51how is it grabbing hold of this object
2:43:52and how does it know what to do with it
2:43:54and
2:43:54as it turns out it has a lot to do with
2:43:57the parameters on the receiving
2:43:59commandlet and that's what i want to
2:44:01show you first of all one of the first
2:44:04things we need to know
2:44:05when we're looking at this is when we
2:44:08send
2:44:09we're sending objects we need to know
2:44:11what kind of objects
2:44:12they are so i piped it to get member
2:44:15because get member shows me what type of
2:44:18object
2:44:19is being sent across the pipeline this
2:44:21is a service controller object
2:44:23i need to know that right now now what i
2:44:26want to do is
2:44:26i want to see what the receiving
2:44:29commandlet is capable of receiving
2:44:32to do that we look at the help file for
2:44:34it the receiving command
2:44:36in this process you have a tendency to
2:44:38get confused between
2:44:39piping to get member and get help but
2:44:41it's pipe to get member to see
2:44:43the object what kind it is and then we
2:44:45look at the help file on the receiving
2:44:47commandlet so
2:44:48let me show you get help on stop service
2:44:51now
2:44:51i'm going to use dash full because i
2:44:53want you to see everything but jeffrey
2:44:54will show you a trick here in a second
2:44:57let me go in here and show you inside we
2:44:59now
2:45:00are very concerned with this information
2:45:02we already know how to look at the
2:45:04syntax i want to go down here and look
2:45:05at the parameters
2:45:06the parameters have a capability
2:45:09sometimes and that capability is
2:45:12do they accept pipeline input now think
2:45:15of these guys
2:45:16as the parameters are the things with or
2:45:18without the catchers met so
2:45:20what we're asking is is do you have a
2:45:21catcher's mitt or not where you could
2:45:23catch this object and do something with
2:45:25it
2:45:25well a lot of times you'll see like
2:45:27display name it it doesn't
2:45:29accept pipeline input so there's nothing
2:45:31going to cross
2:45:32but let's go down this list i often
2:45:34start at the bottom but let's go down
2:45:35this list
2:45:37and this is um stop service so let's see
2:45:39here dash what if well dash what if it
2:45:41doesn't even make sense to accept
2:45:43pipeline input dash confirm
2:45:45no that doesn't accept it pass through
2:45:48that doesn't accept it
2:45:49dash name that does accept it now here's
2:45:53what we're concerned about
2:45:54we have two ways of accepting pipeline
2:45:56input by value
2:45:58and by property name and if you're a dev
2:46:00out there we're not talking about by
2:46:01vowel by ref this is different
2:46:03but by value and by property name
2:46:06the first way we're going to try it is
2:46:08by value and what you're going to notice
2:46:10here is
2:46:10dash name it supports accepting pipeline
2:46:13input by value
2:46:14and it would like some kind of string
2:46:17well
2:46:17wait a second let me show this to you
2:46:19let me go up a little bit further
2:46:21see this parameter called input object
2:46:22i'm not exactly sure what it does but it
2:46:24accepts
2:46:26true by value look at the kind of
2:46:29object it would like a service
2:46:31controller wait a minute wait a minute
2:46:32wait a minute
2:46:33when i did get service what kind of
2:46:35object was i sending it
2:46:37i was sending a service controller so
2:46:39when a service controller comes
2:46:41cruising across that pipeline to stop
2:46:43service
2:46:45the catcher's mitt that's going to grab
2:46:46it is the
2:46:48input parameter catcher's mitt because
2:46:51this name
2:46:52is spelled exactly like service
2:46:55controller
2:46:55of the object type that i sent i know
2:46:58this is weird but
2:47:00they're spelled the same so since
2:47:02they're spelled the same
2:47:03this means we're actually passing it by
2:47:05value and this is the one of the most
2:47:06efficient ways
2:47:08to pass so that's how get service
2:47:11and stop service actually work we're
2:47:13passing by value
2:47:15into the parameter input object
2:47:18because the names match the type of
2:47:21object along with
2:47:22what the parameter expects
2:47:26here's where it gets a little tricky and
2:47:29please jump in
2:47:30as soon as you want to yell at me about
2:47:31something because you're doing great you
2:47:32think so because man this was this was
2:47:34hard on me at first but as soon as i got
2:47:36this this is
2:47:37you got it what made made the world rock
2:47:40let's try this notice that i did get
2:47:42service stop service and i want to point
2:47:44something out to you notice how the
2:47:45nouns match
2:47:46well if the nouns match it's likely
2:47:49that they're going to work together on a
2:47:50pipeline it's also
2:47:52likely that they'll probably pass by
2:47:54value but
2:47:56that's not always the case so you always
2:47:57want to check to make sure
2:47:59let me show you something where the
2:48:00nouns don't match
2:48:03get service stop process well these are
2:48:06two totally different things
2:48:07services processes they're not the same
2:48:10thing
2:48:11so i'll bet most of you are thinking the
2:48:13same thing that i am this
2:48:14isn't going to work it can't possibly
2:48:17work
2:48:18services processes let's go through this
2:48:21process and take a look
2:48:24i'm going to do get service and i'm
2:48:25going to pipe it to get member i know we
2:48:27know the answer to this but i just want
2:48:28to go through the process again
2:48:30what kind of object are we sending we're
2:48:32sending a service controller object
2:48:33across now the first thing i want to
2:48:35check
2:48:35is to see if there's something in stop
2:48:38process
2:48:38that supports pipeline input by value
2:48:42for this object that would be the first
2:48:44way we would hook up
2:48:45so i'm going to do get help on the
2:48:46receiving commandlet which in this case
2:48:48is stop process
2:48:53and let's take a quick look let me get
2:48:56up to the parameters
2:48:58now guys i'm going to shorten this down
2:48:59a little bit because i know some of
2:49:00these parameters just don't accept
2:49:02pipeline input like what if
2:49:03it doesn't accept pipeline input so i
2:49:05don't even need to look at it so every
2:49:06time it says false
2:49:07i'm not really that interested in it
2:49:09passthrough doesn't support it
2:49:11dash name it does support it but right
2:49:13now i'm checking for by value this is my
2:49:15property name so i'm looking for things
2:49:16by value
2:49:18up there we go input object it supports
2:49:20pipeline input it'll catch it
2:49:22and it's doing it by value the first way
2:49:24we're going to do it but look at what it
2:49:26wants
2:49:26a process object well i'm not sending it
2:49:30process isn't spelled the same way as
2:49:33service controller
2:49:36not even close so there's not going to
2:49:39be
2:49:39a hookup here so by value
2:49:43fails well now at this point you kind of
2:49:46go well if it fails it's just not going
2:49:47to work
2:49:48no now we move on to the next process
2:49:51which is by
2:49:51property name and this gets a little bit
2:49:54confusing i want you to notice while i'm
2:49:56in this help file
2:49:57see how the parameter dash name
2:50:01takes pipeline input by property name
2:50:05here's what that's saying the object
2:50:08that you're sending to me
2:50:10does it have a property that is spelled
2:50:14exactly like the parameter name that's
2:50:17what we mean by property name
2:50:18is it spelled the same and if so i might
2:50:21be able to hook up that way
2:50:22if by vowel fails i'll try this so
2:50:26here's what i'm going to do here's the
2:50:28catch phrase whenever you want to know
2:50:30everything there is to know about an
2:50:32object you pipe it to get members so
2:50:34get service and i'm going to pipe it to
2:50:39get member take a look at this list
2:50:43is there a property and remember we only
2:50:46all we need is the word property in it
2:50:48is there a property
2:50:49that is spelled the same way as the
2:50:51parameter name and if you look at the
2:50:53list
2:50:56there is if they're spelled the same
2:50:58we're going to have a hookup by property
2:51:00name
2:51:01but watch what's going to happen here
2:51:04so let's look i'm only going to take one
2:51:06service here
2:51:08service look at what its name is it's
2:51:10the name of the service
2:51:12okay wait a second when you look at
2:51:15processes let's look at processes
2:51:21uh process name is also name
2:51:25these are process names so when you
2:51:28use the commandlet oops clear the screen
2:51:31when you use the command
2:51:32hello clear the screen there we go when
2:51:34you use the commandlet stop
2:51:36process what it wants for its dash name
2:51:39is the name of a process what i'm
2:51:42sending it
2:51:44is the name of a service but here's the
2:51:48thing
2:51:48we do have a hookup this is going to
2:51:51work
2:51:52it's just your results may be a little
2:51:54unusual so let's try it get service
2:51:57pipe to stop process this should work
2:52:00and
2:52:00yeah i'm going to do a dash what if
2:52:02because you know why i'm doing a dash
2:52:04what if because it does
2:52:05actually work notice there's a lot of
2:52:07blood on my screen
2:52:09now what this means is is that yeah look
2:52:11cannot find the process with the name
2:52:14well yeah because that's a service name
2:52:15of course you can't find that but if you
2:52:17look here did you see anything
2:52:19white flyby cause that means
2:52:22it worked let me see if i can find
2:52:24something oh there's always something
2:52:27i didn't see anything really don't
2:52:28embarrass me in front of my friends
2:52:30it's only five thousand or two i know
2:52:32there's there's almost always something
2:52:34in here that's in white
2:52:36go to mine so let me show you guys
2:52:40okay so here's here's i'll do a
2:52:42different set
2:52:43okay cool so notice i started up
2:52:46calculator here
2:52:47right and so i can do get process
2:52:51calc and get calculator and i can pipe
2:52:55that
2:52:56to der and we see that calc
2:53:00is in this and why is that
2:53:03because der takes binds by name
2:53:07and so you take a look and we'll does
2:53:09dur take a process
2:53:10do it you know
2:53:12system.diagnostics.process
2:53:14no and it says oh well i bind anything
2:53:16by name
2:53:17do you have a name and get process does
2:53:20have a name
2:53:21and therefore it works that's an
2:53:24excellent example and so
2:53:25between his example in mind you get
2:53:27what's happening here is that
2:53:29the commandlets are working together but
2:53:31you have to look at what you're
2:53:33giving it the information that you're
2:53:35giving and what it's expecting in the
2:53:36case of my get service stop
2:53:38process if you have a process running
2:53:41that happens to have the same name as a
2:53:43service
2:53:44it's going to get killed off most of the
2:53:47time that's not the case
2:53:48in jeffrey's example i've got a process
2:53:50name that happens to be
2:53:52actually a file i could go looking for
2:53:54so that is a good result
2:53:55that works out can i show them uh
2:53:57actually you know i said that wrong
2:53:59it was actually the path the path that
2:54:01it was the dir yeah
2:54:02so dur takes a path and process uh
2:54:05object
2:54:06has a path now here notice in my screen
2:54:09uh we said oh you know by name well you
2:54:12were doing it by name
2:54:13right gsv b and and
2:54:16notice his name um what is it i want to
2:54:19show you
2:54:20um through
2:54:21[Music]
2:54:23do gm okay
2:54:26so notice this thing here yeah okay
2:54:30name alias property service name so
2:54:33unlike i remember i said that powershell
2:54:37we're focused in on making your life
2:54:39good because
2:54:40those people aren't focused in on that
2:54:42right they're focused in on
2:54:43i'm writing this for myself it's going
2:54:45to be cool or hey you're my developer
2:54:47buddy and we're going to talk developer
2:54:48talk to each other blah blah blah
2:54:50and and so it's pretty inconsistent
2:54:52world we're responsible for trying to
2:54:54make it a consistent world for you
2:54:56so whereas you know um you say
2:54:59server service name and process was
2:55:02process name
2:55:03we want to say no you don't care about
2:55:05all that crap you just want the name
2:55:07name okay and so what we do is we take
2:55:09the type system
2:55:10and remember how i showed you xml we
2:55:12tweaked the xml
2:55:13and we presented to you simpler one of
2:55:15the techniques we do for that is
2:55:17something called an
2:55:18alias property an alias property is with
2:55:20something here we say hey
2:55:22that we have this property name which is
2:55:25aliased
2:55:26to service name so the proper the object
2:55:29itself really only has this thing called
2:55:31service name but we say
2:55:33hey treat it as though it has a name um
2:55:36which and then when you ask for it given
2:55:38the service name and that makes
2:55:39that gives you a simplified uh
2:55:42consistent view of the world
2:55:44and it makes this interoperability stuff
2:55:46work because if it turns out that hey
2:55:48i want to send something to some command
2:55:51and uh it's accepting things by
2:55:53by gojar and i have one of those but i
2:55:56call it a
2:55:57foe right i just go and i say okay well
2:55:59on my foo
2:56:00you know i'm going to map its name to
2:56:02goojar
2:56:04i do that once and then i can send it to
2:56:06you as a matter of fact this is a
2:56:08perfect
2:56:08setup for the next stage in this and so
2:56:12understand what he's he's showing you is
2:56:13that they've done a lot of work to make
2:56:16powershell commands consistent in other
2:56:19words we had a service name on the
2:56:21object
2:56:21but they created an alias property
2:56:24called name
2:56:24so it could work with other commandlets
2:56:26that accept
2:56:28by property name so they they're making
2:56:31it consistent for us
2:56:33but there are times when the greatest
2:56:36minds all think alike but
2:56:38just haven't had a chance to get
2:56:39everything consistent yet
2:56:41let me give you an example where this is
2:56:42going to break down there's
2:56:44one of my favorite commandments is get
2:56:46ad computer and i need to tell you that
2:56:48one of the things you have to be kind of
2:56:49careful with is microsoft
2:56:51especially the product teams when they
2:56:52work with this they they try to help you
2:56:55by not
2:56:55doing dangerous things to yourself i
2:56:57think about the technology underneath
2:56:59what this commandlet's going to do
2:57:00if i run this who has this information a
2:57:03domain controller does so this command
2:57:05has to go out to a domain controller ask
2:57:08the domain controller for this
2:57:09information and then spit this
2:57:10information back
2:57:12look quite honestly that if you only
2:57:14have a couple dozen computers that's not
2:57:16a big deal
2:57:17but if you have 30 000 computers this
2:57:20could be a big deal this could
2:57:22make your domain controller not a domain
2:57:24controller for a while and then when it
2:57:25spits the data back
2:57:27you could have some performance issues
2:57:28for a while so when
2:57:30you're running commands you will notice
2:57:32you know a lot of times you'll do a get
2:57:33command and it'll
2:57:34just run commandlets that might be a
2:57:37little bit more dangerous that's not the
2:57:39case what they do
2:57:40is they put things in them that are
2:57:41mandatory we mentioned this with git
2:57:43event log earlier
2:57:44this is another great command that has
2:57:46an example so let me show you if i just
2:57:47strike enter on get ad computer
2:57:50uh-uh bro you got to give me a little
2:57:52bit more information about this
2:57:54you've got to be you i don't want to get
2:57:56you everything
2:57:58really so i'm just going to put in a
2:57:59star this will work
2:58:01it'll get me everything but notice what
2:58:03i've done i'm the one now that's made
2:58:05the decision
2:58:06to actually get everything so this is
2:58:08the commandment that i'm going to use
2:58:09for a second so let me do this get ad
2:58:11computer
2:58:13and i'm just going to put in the filter
2:58:15star which means i'm going to grab
2:58:17everything
2:58:18and i want to here's my business problem
2:58:20what i would like to do is get the
2:58:21status of the bit service on
2:58:23every computer in the network i know it
2:58:25doesn't sound that creative but it gets
2:58:27better later
2:58:28so get service name bits understand what
2:58:32i'm trying to do
2:58:33i'm trying to get a list of all the
2:58:34computers from active directory
2:58:37and i want them piped to get service
2:58:40and so that git service will then grab
2:58:42the bit service from all of them
2:58:43well here's the thing let's see if we
2:58:46can figure out how this is going to work
2:58:48or not work so first thing is that we do
2:58:52is i go through the whole process first
2:58:53of all pipe to gms to find out what kind
2:58:55of object am i working with
2:58:56i need to know this for by value in case
2:58:58it works for by value so
2:59:00ad computer object sounds great probably
2:59:03ain't going to happen because the nouns
2:59:04don't match but
2:59:0580 computer object great next thing i'm
2:59:08going to do is get help
2:59:10on git service and see if it did
2:59:14see if it supports um uh
2:59:1880 computer object by value
2:59:21and guys i'm going to make this a little
2:59:23bit briefer so rather than scrolling
2:59:24through
2:59:25every and stopping at every single one
2:59:27of them let me just scroll up
2:59:28to the things that say by value can i
2:59:30show them a trick yeah sure so
2:59:32do that again and do minus show window
2:59:35so do show window open window
2:59:39okay and so if you have full now now
2:59:41search by by value
2:59:42oh man see this whole this whole show
2:59:46this whole show window thing is just
2:59:48awesome yeah and then hit next oh wait a
2:59:49minute i have to hit next there we go oh
2:59:52boy there we go what objects see so now
2:59:55look look look we got it except pipeline
2:59:58input
2:59:58you have to watch me scroll true by
3:00:01value we're looking good
3:00:03what kind of object does input object
3:00:04want it wants a
3:00:06sir is that spelled exactly the same way
3:00:08as a d
3:00:09computer no so no hook
3:00:13up by value so close so yeah we're so
3:00:15close
3:00:17so what we're going to do then is check
3:00:19for by property name
3:00:21well i have to take a look at what the
3:00:23properties are and really the only
3:00:25property
3:00:25i care about that i'm trying to send
3:00:27across is whatever holds
3:00:29the computer name so let's take a look
3:00:31at that real quick
3:00:33um get ad computer
3:00:36filter star well gee whiz just take one
3:00:40of them there's a whole bunch of stuff
3:00:42that's
3:00:43being sent across the pipe the only
3:00:44thing i care about though is where the
3:00:46computer name is and that property is
3:00:48called
3:00:49name so let's go back to the show window
3:00:53and see if we have something that
3:00:54supports
3:00:56name so pipeline by property name
3:00:59and so let's do this trick by
3:01:03property name and watch what happens so
3:01:05we'll find him
3:01:07dash computer name hey that supports by
3:01:09prop by property name
3:01:11but but remember what the rule is this
3:01:15has to be spelled exactly like this for
3:01:18by property to hook up
3:01:20and it's not in fact it's not spelled
3:01:23the same
3:01:24but you know what is spelled the same if
3:01:26i go down here oops wait
3:01:27which way down in it lucky
3:01:30aim we do support by property name on
3:01:33something spelled exactly the same but
3:01:36look at what it says
3:01:37it wants a service name so here's what's
3:01:40going to happen if i try to run this
3:01:42i'm going to take a bunch of computer
3:01:43names and it's going to
3:01:45think that i'm giving it service names
3:01:47and unless you named your computers
3:01:49after services which would never be a
3:01:51good idea
3:01:52this is not going to work you know the
3:01:54thing is that
3:01:55it really gets me is god if there was
3:01:58only a way
3:01:59if there only was a way where i don't
3:02:02want
3:02:02this to be called name i want it to be
3:02:04called
3:02:05computer names because it was called
3:02:07computer name then it would
3:02:08it would match and everything would work
3:02:10if there was only a way i could change
3:02:13this property to say computer name
3:02:16and yet there is
3:02:20you are shown you want to show them
3:02:22you've got your computer
3:02:24oh that's you have a computer well let
3:02:25me show them that so
3:02:28let's do the concept so watch guys take
3:02:31a look
3:02:32get service and i'm just going to show
3:02:34you a quick concept
3:02:35i want you to see i'm just going to work
3:02:36with one service to keep it simple
3:02:38you guys have seen us select properties
3:02:41before by the way i don't think you've
3:02:42shown them computer name have you shown
3:02:44a computer name
3:02:45so you know get service works against
3:02:47computers
3:02:48yes oh yeah yeah i should have shown you
3:02:50in the help file you'll see
3:02:51it has dash computer name so i could use
3:02:53this against remote computers
3:02:55which is what i'm trying to get the
3:02:56active directory commandlet to do
3:02:58i'm going to grab name and status and i
3:03:00want you guys to see something yeah it's
3:03:01going to give me the name and the status
3:03:03that's what you would expect but how
3:03:05many of you would expect to get an error
3:03:07if this occurred and usually when i'm at
3:03:08a conference this is exactly what i type
3:03:10because i can't type very well so it
3:03:12usually comes out name
3:03:14status status
3:03:18watch what happens see that
3:03:22do you get what's going on here wait a
3:03:24minute a lot of people think that that
3:03:25should generate an error that shouldn't
3:03:26generate an error that's a feature
3:03:29let me show you i'm going to pipe that
3:03:30to get member
3:03:34look it just created
3:03:38new properties called nam and students
3:03:43so here's the idea i want you to think
3:03:45about this
3:03:46i wonder if i could take the existing
3:03:49property for ad computer called name
3:03:53and change it to computer name and the
3:03:55answer is yes
3:03:56however the answer is yes
3:04:01but let me show you how this is going to
3:04:02work
3:04:04first of all i'm going to select the
3:04:07property
3:04:08name just so you can see i'm not
3:04:11cheating
3:04:12and then i'm going to show you some
3:04:14special syntax and
3:04:15this syntax at first is a little chewy
3:04:18but it's in the help file for the select
3:04:20dash object and it's in the example so
3:04:22it's
3:04:23going to be one of the things you want
3:04:24to learn it's a hash table syntax and we
3:04:26use hash tables everywhere
3:04:28so you're going to spend the time you're
3:04:29going to learn the syntax this syntax
3:04:31you must
3:04:32you must you're just going to keep
3:04:34typing it till you learn it this is
3:04:35something you're going to have to
3:04:36keep in so it's an at sign with an open
3:04:38squiggly and what we have is the word
3:04:40called
3:04:40name equals and now you get to create
3:04:43your own
3:04:44property name what would i what would i
3:04:46like this to be called i want it to be
3:04:48called
3:04:48computer name so i'm going to put in
3:04:50computer name
3:04:53and at this point semicolon and then you
3:04:56specify
3:04:57the expression that will fill that
3:04:59column with data
3:05:01well let's do this expression equals
3:05:05and you're going to put that inside of
3:05:06squigglies and there's one squiggly left
3:05:09over
3:05:10so inside here we want the current
3:05:12object on the pipeline dollar sign
3:05:13underscore or you can use dollar sign ps
3:05:16item for with version three
3:05:18and what do i want from the object
3:05:20that's coming from get a d
3:05:22computer i want the original name
3:05:25property so watch
3:05:27name i'm gonna strike enter and watch
3:05:29what happens
3:05:32dudettes deuces oh
3:05:35i've got myself a computer name now
3:05:38property now let me just show you how
3:05:41you're going to see this on the internet
3:05:42a couple of
3:05:43just quickie things this is a you know
3:05:45here is custom columns
3:05:46calculated properties people use all
3:05:48these terms for
3:05:49for for this but you almost never see
3:05:52everybody type in
3:05:53this full syntax this way they're going
3:05:54to shorten this up to just an
3:05:56e and they're going to shorten this up
3:05:58to just an n
3:06:00and why because because i'm a flawed
3:06:03person
3:06:04i can't talk first and i can't type at
3:06:06all i'm going to figure out how to spell
3:06:08expressions expression i know i know
3:06:10but watch guys i want to i want you to
3:06:11see that this still works so
3:06:13you know i've changed it one other thing
3:06:15i want to show you you're going to see
3:06:16this a lot on the internet and you need
3:06:17to watch out for it
3:06:19used to be that instead of name this was
3:06:22called
3:06:23label and everybody would abbreviate
3:06:25this as
3:06:26an l well i don't know about you but
3:06:28when you see this on a blog post or in a
3:06:31book
3:06:31you can't tell the difference between an
3:06:34l and the number one
3:06:36so a lot of times you'll type it in
3:06:37wrong and you'll go it just doesn't work
3:06:39no if you ever see an l or what looks
3:06:42like to be a one
3:06:43always replace it with an n that way you
3:06:45get rid of
3:06:46all of those little ambiguity i can't
3:06:48say that word but all those little
3:06:50problems
3:06:50and big yeah all these wild cards for
3:06:54speech so
3:06:56let's do this i don't really need this
3:06:59name in here anymore because
3:07:01i've managed to create my own version
3:07:04and i want to show you if you pipe it to
3:07:05get member
3:07:08see it says computer name so lookie
3:07:11when we pass it to the the receiving
3:07:13commandlet
3:07:14computer name is going to match with
3:07:16computer name by property name
3:07:20and lo and behold donald trump
3:07:23drum roll drum roll drum roll and the
3:07:25command was get
3:07:26service name bits
3:07:34oh come on that is so wickedly cool so
3:07:39the guys in the back are going i don't
3:07:40know what the hell he just did but okay
3:07:42we'll go with it
3:07:43but here's the begging for the applause
3:07:45yeah pity applause golf clap
3:07:47um here's the thing is that
3:07:50you know they're working to try to you
3:07:52know give you alias properties to
3:07:54make some consistencies but that's not
3:07:56always going to be the case sometimes
3:07:58you're the one that has to do it in
3:07:59flight to make the consistency
3:08:02using a custom column or calculated
3:08:04property
3:08:05we use these a ton because there's so
3:08:08much we can do with this
3:08:10so much we can do with this and you'll
3:08:12see some more examples of us of us using
3:08:14it in here
3:08:15but we do have the last
3:08:19the last possibility
3:08:22it's my favorite one because everybody
3:08:26yells at me when i do this
3:08:27by the way it's really worth spending
3:08:29time on this stuff this
3:08:30is the heart of powershell this is the
3:08:33core
3:08:34concept it's the core power that's where
3:08:37you get all your magic
3:08:39so learning the stuff like spending some
3:08:41time understanding how it really works
3:08:43uh getting familiar with the wear the
3:08:45pipelining is
3:08:46is the heart of it it's worth an
3:08:47investment well and i just i just have
3:08:49to say
3:08:50and and and this is definitely um
3:08:53for me guys this is what changed my
3:08:55ability to
3:08:57be productive with powershell when i
3:08:59learned
3:09:00this this is what suddenly made
3:09:02powershell
3:09:03oh i got this because i could discover
3:09:05whatever it is i was looking for
3:09:07and now i knew how to put it together
3:09:09and if it didn't work i knew how to
3:09:10troubleshoot it that's the important
3:09:12thing
3:09:12i know we're going through it quickly
3:09:14here but again
3:09:16this is the most important thing and it
3:09:18does it changes it makes you totally
3:09:20productive now i've shown you three ways
3:09:22so far
3:09:23in this it's getting the stuff to work
3:09:25on multiple machines we're going to talk
3:09:26more about remoting
3:09:27but that's where you just become so
3:09:29productive the number of people who've
3:09:31come up to me at tech ad
3:09:32and had stories like there's remember
3:09:35this one guy who said oh well you know
3:09:36his boss brings everybody in on like a
3:09:38tuesday it's like oh we got to get this
3:09:40information from
3:09:41every single one of our servers it's top
3:09:43priority gotta have it by the end of the
3:09:45week
3:09:45call home tell folks you're gonna be
3:09:47working late doesn't matter
3:09:49we gotta get this done he's like uh
3:09:50everybody's like uh
3:09:52and so he goes back to his office he's
3:09:53like wait a minute wait
3:09:55i can do that with powershell he says
3:09:57ten minutes later i had all the
3:09:59information
3:10:00he said it took a couple more minutes to
3:10:01put in an excel spreadsheet
3:10:03yeah so in like 15 minutes i was done i
3:10:06said that's awesome
3:10:06what did you do he says well i went home
3:10:08i took the rest of the
3:10:11and then he year back in the morning and
3:10:12showed his boss this awesome report he's
3:10:14like oh you're a god
3:10:16and that's kind of the point is i want
3:10:18to go home so i want to get this stuff
3:10:20done right
3:10:21and this is a primary way for you to
3:10:23figure out how things work so
3:10:25three ways we've done it so far get
3:10:27service to stop service we matched by
3:10:30value and that's how we're going to try
3:10:31at the very beginning
3:10:33when the nouns don't match by value
3:10:35probably isn't going to happen not
3:10:37always but probably is not going to
3:10:38happen and we did get service
3:10:40stop process where we had to start to
3:10:42match by property name which means
3:10:44the name of the the the the the property
3:10:48coming across
3:10:49has to match the name of the parameter
3:10:51of the receiving commandlet
3:10:53but whenever you do that that's where
3:10:55what if is your friend
3:10:56oh yeah that is where what f is
3:10:58definitely your friend
3:11:00the third way is well
3:11:03there's a parameter that supports
3:11:05pipeline input and you want to use that
3:11:07parameter but what
3:11:08the property you're sending it doesn't
3:11:09have the right name so you can change it
3:11:12in flight using this syntax
3:11:15here's the fourth and final and believe
3:11:18me then we're ready for a break here in
3:11:20just a second so
3:11:22so get 80 computer i want you to
3:11:26understand my business problem
3:11:27first of all to show you there's a
3:11:29commitment we're not going to get a lot
3:11:30of time today to spend with this
3:11:32with the concept of wmi but wmi is one
3:11:35of the greatest things wmi and similar
3:11:36one of the greatest things in the world
3:11:37i'm hoping that a little bit later on
3:11:38jeffrey will be able to have a chance to
3:11:40talk about it
3:11:42but i just want to show you wmi is great
3:11:44for grabbing all kinds of wonderful
3:11:45information
3:11:47here's an example of wmi grabbing just
3:11:49some bios information
3:11:50i also want to point out that this
3:11:52commandlet supports
3:11:53computer name which means i could get it
3:11:55from multiple computers
3:11:57now if i could spell them correctly
3:12:00so understand that this could be really
3:12:02useful to me i might want to do a whole
3:12:04hardware inventory
3:12:05but i'm not going to want to sit here
3:12:07and hand type in a bunch of computer
3:12:09names instead i'm going to want to
3:12:11pipe a bunch of computer names from
3:12:12active directory so what i'm doing is
3:12:14i'm going to say get ad computer
3:12:17filter star
3:12:19[Music]
3:12:21pipe to get wmi object
3:12:24and i want the class for bios
3:12:28well here's the thing you can spend the
3:12:31next
3:12:32two days trying to get this to work
3:12:38ain't gonna happen if you know how to
3:12:39work this process that we're showing you
3:12:41right here
3:12:42here's what you would do and you're
3:12:44gonna solve this problem in seconds
3:12:46rather than days first of all you're
3:12:48going to pipe to gm to see what the
3:12:49object type is because we want to check
3:12:51for by value and i'm just going to tell
3:12:52you right now my value is not going to
3:12:54work
3:12:54i got ad computer but by value is not
3:12:57going to work you know how i know that
3:12:58because the next thing we do is we go
3:13:00look at parameters that support
3:13:02pipeline input well let's do that get
3:13:05help
3:13:06uh get wmi object
3:13:10dash full
3:13:13and guys i i know we could do this uh
3:13:15with the uh the show window but i just
3:13:17want you to see the beauty of this
3:13:19watch as it scrolls by when i get to the
3:13:21parameters
3:13:24throttle limit no recurse
3:13:28no query no property no
3:13:32name space no locale yeah denied
3:13:36um list no uh impersonation fun on a
3:13:40friday night but no
3:13:41it's um filter no every computer says
3:13:45no every parameter says
3:13:49no no pipeline input
3:13:52it will not take any pipeline input stop
3:13:55trying
3:13:56it won't take any pipeline input so i
3:13:57see guys all the time that go
3:14:00okay well then you can't do it it's
3:14:02broke they need to fix that with
3:14:03powershell
3:14:04well no you can do it you just have to
3:14:07know how
3:14:08let me show you you know i was showing
3:14:10you that
3:14:11how this commandlet get help and i'm
3:14:14going to do the short help for it
3:14:16this guy supports dash computer name
3:14:19well here i want you to take notice here
3:14:20let's look at dash computer name see
3:14:22dash computer name
3:14:23and what he wants is a bunch of strings
3:14:26that's what he wants
3:14:27as an object strings he'll take dash
3:14:30computer name i just have to figure out
3:14:31how to get it
3:14:32in there get those computer names in
3:14:34there so
3:14:35here's what i'd like to do get wmi
3:14:39object whatever class i want
3:14:44and i would like to do dash computer
3:14:47name and
3:14:48get the computer names in there i'd like
3:14:49to do like get ad computer
3:14:52filter star well you can't do that
3:14:55because it
3:14:55screws up the argument so you have to
3:14:57put them in parentheses because remember
3:14:59what parentheses means i wasn't a big
3:15:01math fan
3:15:02but they those things are like order of
3:15:04operands or
3:15:06you're a smart guy you know all that
3:15:07stuff it's it's it means
3:15:09do this first before we do anything else
3:15:12so what's going to happen is
3:15:13what's ever in those parens is
3:15:15parenthetical it's going to do that
3:15:17first
3:15:18and that becomes the argument on this
3:15:20dash computer name
3:15:21but there's a small problem remember
3:15:23dash computer name wants
3:15:25a bunch of string objects i wonder what
3:15:28this is providing me as a matter of fact
3:15:30let me show you get
3:15:32ad computer and you know how to do this
3:15:33now filter star
3:15:35what kind of object is this producing
3:15:37pipe it to gm
3:15:39it's giving me ad computer
3:15:42that doesn't say string watch
3:15:45also it's giving me way too much
3:15:48information
3:15:50this is giving me all kinds of stuff i
3:15:52don't want i just want name i just want
3:15:54to select
3:15:55i just want to select name so get ad
3:16:00computer
3:16:03filter star select the property
3:16:07name awesome i've got the names this is
3:16:10what i want to throw into dash computer
3:16:12but
3:16:13before we try this check it with get
3:16:16member
3:16:17look at what the object type is 80
3:16:20computer
3:16:20it doesn't say string here
3:16:24so it's going to break well they thought
3:16:26of this they solved this what i really
3:16:28want
3:16:29is i want to
3:16:32extract those names and put them in that
3:16:35dash computer name argument in between
3:16:37the two of
3:16:38us i want to extract or extract
3:16:41extract isn't the right word i want to
3:16:45expand this property now we can only
3:16:48expand one
3:16:49but look at the difference on my screen
3:16:51how this looks
3:16:53see how you don't have this anymore
3:16:56it's just the names of the computers
3:17:00let's pipe it to get member
3:17:05lookie string
3:17:08string happy happy happy happy so
3:17:12what we do is we and i'm going to try to
3:17:14do this i'm going to try to right click
3:17:16on this
3:17:18and here's what we're going to do right
3:17:21yeah right click i i think i did that
3:17:22right so
3:17:24get wmi object whatever class i wanted
3:17:28win32 underscore bios
3:17:30dash computer name and here's what i
3:17:32want to put inside of the parentheses
3:17:34that whole thing now you might be saying
3:17:38gee whiz
3:17:38that's an awful lot of work but as soon
3:17:40as you do this like two or three times
3:17:42it's not a lot of work because now what
3:17:45you couldn't solve
3:17:46before or you were spending days banging
3:17:48your head on
3:17:50now just works and it just works because
3:17:53we couldn't pipeline to this commandlet
3:17:55darn okay forget about it that's fine
3:17:58what do you want to use i want to use
3:18:00dash computer name what does it want it
3:18:01wants a string so i want to grab all the
3:18:03aed computers i just want the property
3:18:05name
3:18:06i don't want all the other properties i
3:18:07just want name send it to get
3:18:09member it's not a string oh i need to
3:18:11expand that
3:18:13think extract that those values out
3:18:17and i get the string now it's going to
3:18:19work
3:18:20this is your last line of resort now
3:18:23don't use this as your first line of
3:18:24resort
3:18:25that's not the point because you want
3:18:26the power of the pipeline
3:18:28so don't do this first do this last and
3:18:32let me show you and we're going to let
3:18:33jeffrey talk about this for a second is
3:18:34that
3:18:35before we take a break let me show you
3:18:37what i found out microsoft's kind of
3:18:39doing to help us out
3:18:41you know how the the get wmi thing
3:18:45it doesn't take any pipeline input well
3:18:48i happen to know that there's wait
3:18:50before you go there okay
3:18:52up arrow up arrow because this works
3:18:55perfectly this works perfectly
3:18:57but this works in powershell version two
3:19:00powershell version three we made it
3:19:02simpler
3:19:04oh let's make it simpler hit delete
3:19:07uh delete the select
3:19:11oh no no all the way from the end of the
3:19:13line to the slide away from the other
3:19:15one
3:19:16get rid of that get rid of all that yeah
3:19:19more
3:19:19more line okay now in paren
3:19:22and parentheses that's again prin
3:19:27oh end parent yeah okay space oh i see
3:19:30what you're doing oh
3:19:33[Music]
3:19:36basically is shorthand uh
3:19:40syntax to do that selects which is what
3:19:42you were showing earlier with
3:19:44casting to xml and guys one of the
3:19:46things is we're going to start showing
3:19:48you as we get close to scripting
3:19:49we're going to be showing you working
3:19:50with variables and using this dot syntax
3:19:53this dot
3:19:54syntax so you get more and more
3:19:56comfortable with it because now
3:19:58that was a lot easier to type as soon as
3:20:00you know more about that dot syntax so
3:20:02this is
3:20:03awesome see it still worked and as
3:20:06i just showed oh let me show you again
3:20:08because i don't think the thing was on
3:20:10there let me show you
3:20:11that oh what's going on is this hard for
3:20:13you
3:20:17i could go over there well no it's it's
3:20:20it's it's
3:20:21something has gone awry and i think my
3:20:24ah there we go something computer we
3:20:26were waiting on so
3:20:28this syntax if you can see it is it
3:20:29works the exact same way um so i can
3:20:32execute it but i don't want to do it
3:20:33again because
3:20:34it was holding up on one of the machines
3:20:35oh was it one last thing to show you and
3:20:37then we'll take a break
3:20:39is get wmi object doesn't support any
3:20:42input but
3:20:43there's an if you're working with wmi
3:20:45there's a whole new way of doing this
3:20:48and if you were to do get help on
3:20:50something called
3:20:51get sem instance and you were to take a
3:20:55look at the parameters and what they
3:20:57what parameters accepted pipeline input
3:20:59you would see that
3:21:00this is now the replacement for
3:21:04this because the new one
3:21:07now supports pipeline input in the
3:21:09places where you want it to support
3:21:10pipeline input so
3:21:13the idea is that going forward some of
3:21:15the commands that you may run across
3:21:16especially if they're four or five years
3:21:18old that didn't support pipeline input
3:21:20may start to support it but if it
3:21:22doesn't you do have this last
3:21:24line of resort now as a final note
3:21:27make sure this is so very important well
3:21:29you got
3:21:30i was going to show them one more thing
3:21:31oh go ahead show them one more thing i'm
3:21:33going to take over your machine
3:21:34okay it's all yours man okay just did
3:21:36that work yeah right of course
3:21:38okay here we go where are you
3:21:41okay i'm taking over his machine he's
3:21:42gonna take over my machine while he's
3:21:44taking it over
3:21:45get don jones's book uh learn windows
3:21:49powershell in a month of lunches
3:21:51chapter nine you've got to know that
3:21:53that's the most important thing that's
3:21:54what we just did in here
3:21:57okay so now i'm gonna show you something
3:22:00crazy freaky
3:22:01freaky freaky freaky powerful oh let's
3:22:03get freaky yeah we're gonna get freaky
3:22:05freaking
3:22:06okay sorry
3:22:10okay so so now this is this is pretty
3:22:12advanced stuff
3:22:13um but why not end
3:22:16on something really powerful okay and
3:22:19this is something
3:22:20called um what do we call these we call
3:22:22these script parameters
3:22:24i think it's the term form so now what
3:22:26we're going to do is remember the
3:22:28original problem was
3:22:29get ad computer must filter
3:22:34star pipe to get wmi object
3:22:39win32 bios and it was this computer name
3:22:43that we couldn't get a value for right
3:22:45darn
3:22:46okay so here's the deal
3:22:49script block whenever you see the what
3:22:51do you call them the the squigglies
3:22:53squigglies
3:22:54i like to see my hips myself but for
3:22:56those who see the squigglies
3:22:57that's called a script block that
3:22:59represents code
3:23:01if you give a script block
3:23:04to a property to a parameter which
3:23:07doesn't take a script block
3:23:09then what it is is oh that you must be
3:23:12asking for a
3:23:13script parameter and what it does
3:23:16is it takes the value of the current
3:23:19object
3:23:20assigns it to dollar sign under bar and
3:23:23runs the script
3:23:24and takes the value and puts it in there
3:23:27oh this could be totally awesome and so
3:23:29what you do is you say
3:23:30dollar sign under bar dot was it was it
3:23:32name it was name
3:23:33name okay by the way you can do anything
3:23:35you want here you could say two upper
3:23:37or you know anything but here we just do
3:23:40this
3:23:40so again what's gonna happen is you're
3:23:42going to run this
3:23:44you're going to take the current object
3:23:46you're going to assign it to
3:23:47this and then you're going to run this
3:23:50code
3:23:50and so each object you're going to get
3:23:52the value of the name
3:23:54and then you're going to run this with
3:23:57the value
3:23:58was that crazy powerful you know you
3:24:00realize that you've made that so much
3:24:02easier that
3:24:03there everybody's going to like you
3:24:04better than they like me now because i
3:24:06i drug them through this plan okay well
3:24:09it worked because i took them through
3:24:10that long thing
3:24:11and then you just made it really short
3:24:13and sweet so congratulations very nice
3:24:15there you go so have fun with that so
3:24:19folks
3:24:19we're going to go ahead and take a 10
3:24:20minute break when we come back we can
3:24:22get some coffee
3:24:23yeah oh yeah yeah give me some coffee
3:24:24because i need more and um
3:24:26we're going to go into something that is
3:24:28going to change the way you manage
3:24:30now you're going to take the tools that
3:24:31you started to learn today and we're
3:24:33going to get into
3:24:34one of the most powerful things in the
3:24:35world remoting and we want to talk to
3:24:38jeffrey about remoting before we get
3:24:39into it this is
3:24:40totally awesome stuff so see you guys in
3:24:4210 minutes
3:25:00[Music]
3:25:09we're back and i have to tell you we're
3:25:11here to talk and this
3:25:12now we're going to talk about one of my
3:25:13most favorite things and you get to talk
3:25:16about it
3:25:17and we're going to do this twice guys
3:25:18we're going to do kind of a short
3:25:20section of this to get you started then
3:25:21we're going to get into scripting
3:25:23teach you about variables and stuff and
3:25:24then hit remoting this topic
3:25:27again with something called sessions
3:25:29that'll be outstanding but
3:25:31remoting this changed how i manage
3:25:35in scale when it comes to the entire
3:25:37windows uh
3:25:38all the products the platform everything
3:25:41this when it released with version two
3:25:43literally made me a hero overnight so
3:25:45you have to tell us about
3:25:47what were you trying to solve with this
3:25:49what does this thing do this is
3:25:51unbelievable stuff yeah so in in
3:25:53powershell we have this idea we called
3:25:55it
3:25:55we talked a lot about in the past we
3:25:56don't talk so much about it now because
3:25:58because we already delivered it
3:26:00this notion of universal code execution
3:26:02right which is to say that you have
3:26:04code and sometimes you want to run the
3:26:06code here
3:26:07yeah that's what we do everything we've
3:26:09been showing you today
3:26:10we bring up a console window and we type
3:26:13the code
3:26:14and the code runs here but actually it's
3:26:17a generalization
3:26:18like here is a generalization or a
3:26:20specialization of
3:26:22anywhere like sometimes i want to run
3:26:23the code there and sometimes i want to
3:26:25run the code
3:26:26there and sometimes i want to run the
3:26:28code on those machines
3:26:31and sometimes i want to run the code on
3:26:32those machines as
3:26:34myself and sometimes i want to give a
3:26:36different set of credentials
3:26:38and sometimes i want to run it and get
3:26:40the results back immediately
3:26:41and sometimes i want to run it and i'll
3:26:43get the results back later
3:26:45and sometimes i want to run it in a way
3:26:46that uh um
3:26:48i can do anything and sometimes i want
3:26:50to run in an environment where
3:26:52no no no these are and only these
3:26:54commands you can run
3:26:55secure environments and so there's this
3:26:57notion of this
3:26:58universal code execution model oh by the
3:27:01way sorry the last one was
3:27:02sometimes i want to run it i'm going to
3:27:04run it for such a long time
3:27:06that i might want to like shut down the
3:27:07machine and bring it back up and have it
3:27:10continue to run
3:27:11right go somewhere else and maybe check
3:27:13on it or something exactly
3:27:14so this is the notion of the universal
3:27:17uh
3:27:18code execution model and remoting of
3:27:20course is intrinsic to that
3:27:22coupled with that are notions like jobs
3:27:25jobs are things that run in the
3:27:27background and then workflow which we
3:27:29added in powershell version three which
3:27:30is the idea that says hey i'm going to
3:27:32run this
3:27:33and at any stage after any command i can
3:27:35suspend things
3:27:37shut down the machine bring it back up
3:27:40and continue
3:27:41from where i started now see this sounds
3:27:43awesome now what we had before is like
3:27:45um
3:27:45with like the remote server
3:27:47administration tools i have a graphical
3:27:48like active directory users and
3:27:50computers
3:27:50it will connect to a domain controller
3:27:52over dcom using rpc
3:27:54right and there's there's a lot of
3:27:56challenges and problems with that
3:27:57firewall challenges right
3:27:59and all kinds of a mess but what you may
3:28:02which
3:28:02what you guys created though solves all
3:28:05those
3:28:06all those problems exactly so here's
3:28:07what we did was first was we wanted to
3:28:09solve all those problems so http
3:28:11super important next was we already had
3:28:14a pro protocol that went over http
3:28:16our standards-based management so you
3:28:18probably heard we talk a lot these days
3:28:20about standards-based management
3:28:22in fact you know what at tech heads and
3:28:24such i'll show up i'll i'll bring up a
3:28:26linux box
3:28:27and i'll show how on a linux box i can
3:28:29enumerate all the roles on a remote
3:28:31windows server
3:28:32and then install roles on a remote
3:28:35windows server from a linux box i mean
3:28:37just
3:28:38crazy stuff right yeah i saw you do that
3:28:41demonstration for the first time i think
3:28:42it was like a year and a half ago and i
3:28:43just went
3:28:45just explode so this is because of this
3:28:48standards and uh and when rm
3:28:50the winram or ws management protocol
3:28:52winner is our implementation of that
3:28:54and so for powershell remote we leverage
3:28:56winram
3:28:58and we added streaming extensions to it
3:29:01so that's how it works and when rm is
3:29:03the service that you're going to see
3:29:04that's that's running underneath all
3:29:05that as a matter of fact i got a a
3:29:07couple of slides
3:29:08uh here and then we'll talk some more
3:29:10about this if you take a look at the
3:29:12slide here as an overview of remoting
3:29:13basically what this comes down to
3:29:15is you can go and touch
3:29:18just as jeffrey went through the
3:29:20scenarios using what you've already been
3:29:22typing in at the console
3:29:24locally you can pick that up and now
3:29:26fire that
3:29:27at whatever it is you want to fire it at
3:29:29and it's over remoting which is going to
3:29:31give us a lot of cool characteristics
3:29:33it's going to be fast it's going to be
3:29:35easy to cross
3:29:36firewalls because we only have one port
3:29:37to deal with and we're dealing with a
3:29:39secured port so here's the idea if your
3:29:41machines are in a domain
3:29:43this isn't going over just http plain
3:29:45text it's getting all encrypted
3:29:47all encrypted with kerberos and then of
3:29:49course if you're going across
3:29:51the internet or across firewalls and you
3:29:53want to put on ssl or if
3:29:54you even want to do ssl internally you
3:29:57can put on ssl you want that full
3:30:00encrypted tunnel so well just be clear
3:30:01we'll encrypt it twice we'll encrypt it
3:30:03twice at that point yeah
3:30:05if you really need it twice the
3:30:06encrypted we'll do it twice um
3:30:08but here's the idea is that you're
3:30:10hitting whatever machines you want
3:30:13securely and with what credentials you
3:30:15want
3:30:16and nobody can tell i mean nobody can
3:30:18read it nobody can use a protocol
3:30:20sniffer and sniff out what's going on so
3:30:22this is actually
3:30:23really cool stuff so you know there's
3:30:25there's
3:30:26enabling remoting is definitely
3:30:30one of these things that that comes up
3:30:31first of all we we just you know we just
3:30:33need to tell everybody that
3:30:35that you have to turn remoting on kind
3:30:37of sort of maybe
3:30:39kind of sort of maybe because um in
3:30:42prior versions
3:30:43not server 2012 but in prior versions
3:30:45remoting had to be turned on and this
3:30:46can actually be
3:30:48kind of a hard conversation for some
3:30:49security people to have or
3:30:51some admins to have with their security
3:30:52people in
3:30:54in that i'm going to turn on this really
3:30:55cool thing that lets me do whatever i
3:30:57want to whatever i want the security guy
3:30:59goes
3:30:59no which is exactly what they should say
3:31:02but as soon as they understand remoting
3:31:05and how it works
3:31:06all of a sudden it's like oh well this
3:31:07is yeah this is perfectly fine yes
3:31:09so there's this conversation that has to
3:31:11have to get it turned on
3:31:13if you guys take a look at the the slide
3:31:15here
3:31:16what i've done is i've shown you a basic
3:31:18way to turn it on i'm actually going to
3:31:20demonstrate this on one of my machines
3:31:22here
3:31:22but there's a commandlet that you can
3:31:24you can turn that you can use called
3:31:25enable dash ps remoting
3:31:28and now you can you want to walk around
3:31:30to all of your servers and type enable
3:31:32ps remoting
3:31:33knock yourself out but there's a group
3:31:36policy and i have it written down here
3:31:37for you
3:31:38it's much easier if you use the group
3:31:40policy to enable remoting
3:31:42but here's the deal you have to turn
3:31:45this on let me say it again
3:31:49you have to turn this on
3:31:53i'm we're going to show you all these
3:31:54great features but none of it's going to
3:31:56work until you turn on remoting
3:31:58it's not necessarily an easy
3:31:59conversation there's a free ebook
3:32:01on powershell.org secrets about remoting
3:32:04yeah great book which will take give you
3:32:07not only take you through every possible
3:32:08scenario
3:32:09but will is the information that your
3:32:11security guys need to know
3:32:13so that they understand that it's
3:32:14secured and what ports it uses
3:32:18this has to be turned on it's not
3:32:20because i'm just saying it it's because
3:32:21you're running out of options now
3:32:23a lot of the new administrative
3:32:25graphical tools are made
3:32:27to use powershell and powershell
3:32:29remoting server 2012 is a great example
3:32:32of the new server manager right it's
3:32:33using
3:32:34all of these capabilities that are built
3:32:36in and if you don't have it turned on
3:32:38you can't manage anything with anything
3:32:41so you've got to get it turned on and as
3:32:43a side note
3:32:44server 2012 it's turned on by default
3:32:48oh yeah so it's gonna get turned on just
3:32:51to be clear on that one
3:32:52so as you know uh uh we are secure by
3:32:55default and released by release
3:32:57we continue to shut things off by
3:32:59default and
3:33:00you have to turn them on uh in the
3:33:02course this has been going on for quite
3:33:04a number of years
3:33:05been exactly to my knowledge one time
3:33:08where we went the other direction
3:33:09where we turned something on by default
3:33:11instead of off by default
3:33:13and that was uh power it's got to be
3:33:15powershell remote
3:33:16shell remoting that's right so for
3:33:17windows server 2012 we turned on
3:33:20powershell remoting
3:33:21it was a big issue the security security
3:33:23guys are like
3:33:24what are you talking about maybe you
3:33:26didn't get the memo we're going the
3:33:27other direction
3:33:28it's like okay well let's talk about
3:33:30that why is that and the answer is of
3:33:32course windows server 2012
3:33:34right it is a cloud operating system a
3:33:36cloud operating system says hey it's not
3:33:38about this server it's about
3:33:40these servers i need to be able to
3:33:42manage things and therefore remoting of
3:33:44large numbers of systems is critical
3:33:46function it is the core
3:33:47of a cloud os and so they said okay well
3:33:50i'm willing to entertain that i mean
3:33:52that makes sense
3:33:53but we got to be sure and say okay well
3:33:54let's walk through it and we showed them
3:33:56all the things that we had done
3:33:57actually they've been involved all along
3:33:59uh and step by step by step we went and
3:34:01did the threat analysis and they were
3:34:02convinced yeah
3:34:03this is safe to do and so when you have
3:34:06that conversation with your security
3:34:07guys
3:34:08you just point to that and the history
3:34:10of this environment this
3:34:12server one time we switch and turn
3:34:14things on by default it is
3:34:16powershell remoting so go for it yeah
3:34:19and i think that's a really great
3:34:20concept because microsoft's not going to
3:34:21turn on something
3:34:22that is a an easy to use attack surface
3:34:25it's just not going to happen so we put
3:34:27an extraordinary amount into the
3:34:29security of making sure that this is
3:34:31going to be secure environment
3:34:32we've got pen testers who've been
3:34:34evaluating the design
3:34:36the code etc we spent a lot
3:34:39look we started powershell after bill
3:34:42gates
3:34:43his famous um security memo yeah
3:34:46right so and and what started that
3:34:48security member what started that whole
3:34:50bufferama
3:34:51i love you i love you man.vbs oh you're
3:34:54talking about that i was just saying i
3:34:56love you man i'm
3:34:57sorry oh that's special okay okay
3:35:00there's anything wrong with that no it
3:35:03was
3:35:03it was scripting scripting had caused
3:35:05that big i love you
3:35:06mass and so we knew that scripting was
3:35:09going to be a key
3:35:10vector so we just spent a ton of time
3:35:13making sure we were secure secure secure
3:35:16so now that we've jumped up and down
3:35:18enough that you not only have to turn
3:35:20this on but it's secured to have it
3:35:21turned on
3:35:22get it turned on let's start to show you
3:35:24some of the cool things that you can do
3:35:25now like i said we're going to hit this
3:35:26topic twice
3:35:27as we learn more and more about it so we
3:35:29this is all in the slides but
3:35:31um let me take you through here and as
3:35:33soon as i can
3:35:35there we go
3:35:38well maybe not quite i can do something
3:35:42i think you have control of my machine
3:35:44no i keep it up
3:35:46okay my machine is just moving slow for
3:35:48a second i don't oh here we go okay
3:35:50so let me do something real quick and
3:35:52jeffrey please jump in
3:35:53first of all i'm going to do what's
3:35:54called a one-to-one connection this is
3:35:56in
3:35:56you'll see exactly watch i'm going to
3:35:58type in enter it's a commandment
3:36:00ps session powershell session and i'm
3:36:03going to put in a computer name that i
3:36:05want to go to
3:36:06i'm just going to say dc it's one of the
3:36:07vms that i have running
3:36:09watch what happens to my prompt here you
3:36:12see what happened
3:36:14guess guess where i'm sitting right now
3:36:17guess
3:36:18where i am right now i'm on the dc
3:36:22i'm on the dc you don't believe me watch
3:36:25i i'm going to clean up this path a
3:36:27little bit
3:36:28watch host name
3:36:32and i'll do ipconfig that information is
3:36:35coming from the dc
3:36:37so i can actually do a one-to-one
3:36:39connection and i can troubleshoot and i
3:36:40can manage
3:36:42a single system this way as if i was
3:36:44sitting on there as a matter of fact
3:36:46think of this as a secure telnet a
3:36:48secured telnet i love that and
3:36:50and here's let me show you why i think
3:36:52that this is also so important
3:36:54that you just get used to managing
3:36:56servers when you just need to do one
3:36:57thing to one server this is a great way
3:36:59to do it
3:37:00get used to this because i have you guys
3:37:02seen um server 2012 let me exit out of
3:37:05this and let me just show you
3:37:06um i'm going to go out to uh
3:37:10my domain controller and we're going to
3:37:11show you uh server 2012. um
3:37:14this is uh to me fascinating um
3:37:18welcome aboard there it is by the way
3:37:22what you guys did with the color scheme
3:37:23on here is awesome
3:37:25yeah the background the color scheme
3:37:27this is totally
3:37:28totally awesome like in its simplicity
3:37:30it's very zen like in its simplicity
3:37:32yep you guys probably figured out that
3:37:34this is definitely this is
3:37:36you know we used to call refer to this
3:37:38as the core installation and yeah with
3:37:40server 2012 this is now the
3:37:42default installation so and for a good
3:37:45reason
3:37:46performance security all that kind of
3:37:49stuff so
3:37:51let me show you you would be managing
3:37:53the server that way
3:37:54anyways and i don't want to screw this
3:37:56up so let me get rid of him
3:37:58there we go so doing that single session
3:38:02that enter ps session to a machine that
3:38:04you want to do work on it gives you that
3:38:06one-to-one connection and you can now do
3:38:08whatever you want on that machine
3:38:10but here's the big one and so let me
3:38:13exit this
3:38:15you guys been watching all day long and
3:38:16you know you're going to be doing a lot
3:38:18of good hard work on stuff like this i
3:38:19want to do get event log
3:38:21log name system
3:38:24and i'm just going to do newest three
3:38:27now i could do entry type
3:38:28and all this other stuff but i just want
3:38:30to keep it short and simple because
3:38:32let me just show you i'm going to take
3:38:33this and i'm going to copy this what i
3:38:35can get to work
3:38:36here and what jeffrey was saying is the
3:38:39whole point is
3:38:40we'll work anywhere so here's what i'm
3:38:42going to do
3:38:43i'm going to invoke
3:38:47command this is a remoting command
3:38:50what computers when you use this dash
3:38:53computer name
3:38:54it's using powershell remoting not the
3:38:56old dcom rpc stuff which is what a lot
3:38:59of the older commandlets use so this
3:39:00one's using the good stuff
3:39:02and then whatever you put in the
3:39:05squigglies is exactly what we're going
3:39:06to do
3:39:07oops sorry wait a minute put in some
3:39:10computer names and i'm going to be brave
3:39:12and risky whatever you put in the
3:39:15squigglies
3:39:16is exactly what we're going to do and in
3:39:18this case
3:39:20watch boom
3:39:23so over remoting we've was that was that
3:39:26was that approval back there that we
3:39:27heard a knock or something uh
3:39:30that i want you to get that what just
3:39:32happened is by using powershell remoting
3:39:34i just hit
3:39:35three different systems all at the same
3:39:37time and said give me this information i
3:39:39can now
3:39:40convert this i can put it to a file i
3:39:42can put it to a web page whatever it is
3:39:43i want to do with it
3:39:45but i just used powershell remoting and
3:39:47i and
3:39:48and and jeffrey this is actually so
3:39:50powerful that
3:39:51admins need to be a little careful right
3:39:53because things like
3:39:55um uh computer oh yeah that's a good one
3:39:58um
3:39:59restart computer all of a sudden take on
3:40:02a whole new dimension
3:40:04because whatever you fill that with
3:40:06that's what it's going to do
3:40:08dash computer name i can be grabbing the
3:40:09computers from active directory a csv
3:40:11file a text file making me nervous man i
3:40:14know at the moment i'm actually very
3:40:15nervous too i need to get rid of that so
3:40:17that's
3:40:17actually nice and so it's going to
3:40:20restart those machines
3:40:22so this is a one-to-many connection now
3:40:25jeffrey one of the
3:40:25things that comes up all the time is if
3:40:27i do get service i'll do name bits
3:40:30how's this working i mean it's it's
3:40:32actually sending the commands to the
3:40:34machine
3:40:34and then how am i getting this data back
3:40:36yeah so literally what happens is we go
3:40:38and we create a connection to that
3:40:40remote machine
3:40:41right so there's a tcp connection we
3:40:44then
3:40:45fire up a powershell connection we
3:40:48load.net we load powershell
3:40:50we take that code and we squirt it
3:40:53across the wire
3:40:54we then execute it you know we logged
3:40:56you in
3:40:57use your credentials to log you in we
3:40:59then execute the code there
3:41:01and then we get those objects and we
3:41:03serialize those objects
3:41:06we move them across the wire and then we
3:41:08reconstitute them we deserialize them
3:41:11and emit them as though they happen here
3:41:13okay okay so let me see if i get this
3:41:14straight because you're gonna have to
3:41:15explain the serialization
3:41:16yes let me see if i can get this
3:41:18straight so we're connecting to these
3:41:19remote
3:41:19machines and we're actually starting a
3:41:21power shell session
3:41:22on those machines and having the command
3:41:25run
3:41:26on those machines so it's not my
3:41:28computer working harder it's those
3:41:29machines that are doing the work
3:41:31yep now the serialization you're
3:41:33squirting this stuff back
3:41:34serializes serialize deserialize
3:41:38what does this mean exactly so what we
3:41:40do is we we take the object
3:41:42and we transform it into something that
3:41:45can be moved around
3:41:46and reconstructed anywhere okay okay so
3:41:49concretely i mean anywhere like i'm over
3:41:52here
3:41:53i go talk to your machine and it's
3:41:55windows talking.net
3:41:56and then i could bring it over here and
3:41:58it could be linux now there's no
3:42:00net on linux so how's that going to work
3:42:02right and so i've got to serialize it
3:42:04into something that can work
3:42:05anywhere now imagine i go and i say well
3:42:08hey i
3:42:08talk to exchange version whatever
3:42:12and i get the objects here but i don't
3:42:14have exchange here
3:42:16so how do i recreate exchange objects
3:42:18again that's the problem so what we do
3:42:20is we take these objects
3:42:22and we turn them into essentially a
3:42:23property bag you know just a bag
3:42:26of properties and then we take them and
3:42:28you know the properties have names
3:42:30and values and the values have types now
3:42:32here's the trick
3:42:34the types are not the infinite set of
3:42:36types
3:42:37there right if you tried to do that it
3:42:39would never work
3:42:40so what we do is we render it down to a
3:42:42set of i think 26 or so
3:42:44types which you know i put my badge on
3:42:46the table and i say if this
3:42:48i guarantee that these will always work
3:42:50if these don't work
3:42:51fire me well there you go forever
3:42:54forever because you know what
3:42:55um a uh an exchange
3:42:59uh mailbox 30 years from now probably
3:43:02going to change
3:43:03but i'll guarantee you this a 64-bit
3:43:05integer isn't going to change
3:43:0630 years from now yeah right so it's
3:43:08those type of things
3:43:10integers strings uh ins guides
3:43:13things like that are going to be yeah
3:43:16the same
3:43:17exactly so then i take that property bag
3:43:19and i just uh
3:43:20uh turn it into xml i then bring it over
3:43:23here and then i reconstruct the property
3:43:24back
3:43:25and so in fact here do do the by the way
3:43:28uh let me correct something
3:43:29show your screen okay okay so you said
3:43:32that this was
3:43:33remoting in fact invoke command is not
3:43:35remoting
3:43:36well what is it command is the way we do
3:43:39everything
3:43:40remember we have this kind of underlying
3:43:42system and then we've got
3:43:43we've got a great syntactic syntax
3:43:45syntax
3:43:46sugar on top of it so go remove the
3:43:48minus computer name
3:43:50so let's do this yeah well that whole dc
3:43:54one two three
3:43:55dc get rid of that
3:43:59okay and hit care to turn okay okay
3:44:02so that worked locally and that's the
3:44:04same as is if you hadn't typed
3:44:06invoke command and squiggle brackets or
3:44:08rather say when you just type get
3:44:10service minus name
3:44:11bits we transform it into this and then
3:44:14we run it
3:44:15and then we run it and that's that
3:44:17universe this is the universal code
3:44:19execution
3:44:20and this is this is what makes it so
3:44:22easy for especially if you're an
3:44:23administrator
3:44:24you work out what you want first
3:44:28then you can just put it in the
3:44:30squigglies and it's going to work at the
3:44:31other side
3:44:32exactly so from here pipe that to
3:44:34[Music]
3:44:36put that to get member okay and scroll
3:44:40up
3:44:42and what do we have we've got a service
3:44:45no look at the beginning
3:44:47system system dot service process that's
3:44:50service control
3:44:52now add a computer name to that line
3:44:55oh yeah so let's do this let's have it
3:44:58go to
3:44:59uh let's do uh dash comp and
3:45:02dc one okay this one yeah whatever
3:45:05now go on look at the beginning
3:45:09it's seriously serialized ding ding ding
3:45:11ding ding now
3:45:12a de-serialized object is incredibly
3:45:15powerful
3:45:16but it's different okay so if you scroll
3:45:18up a bit
3:45:20oh i'm scroll down did you did you just
3:45:22clear
3:45:23you didn't clear i did a clear okay
3:45:26don't do it clear and and do it again do
3:45:28the local command
3:45:32okay notice see these methods right okay
3:45:35see the start and the stop method top
3:45:37yeah okay
3:45:38that's because it's a live object and
3:45:41you can do methods on it
3:45:42go up to the deserialized one yeah it's
3:45:45it's it's there's there's just one
3:45:47method two strength or two strings
3:45:49exactly because the object itself is
3:45:51gone and what you have is a represent
3:45:54representation of the object now it
3:45:56turns out that that's
3:45:57extraordinarily powerful now some people
3:45:59say oh well it should be the same
3:46:00everywhere no
3:46:01no no my friends it shouldn't be the
3:46:03point is that because we have this
3:46:05this live deserialized
3:46:09concept what it means is that when i'm
3:46:11over there i'm able to take advantage of
3:46:13the
3:46:13remote i'm able to take advantage of the
3:46:16full richness of the object system
3:46:18be able to do everything in a very
3:46:20lightweight way
3:46:21very high performance low latency way
3:46:24and then
3:46:25when i bring it over here i can still do
3:46:27a ton of stuff but i can't do that so
3:46:28the way we refer to this is
3:46:32islands of optimization in a sea
3:46:35of interoperability okay let's islands
3:46:38of
3:46:38optimization in a sea of
3:46:41interoperability of interoperability
3:46:43which is to say
3:46:44it's it's it's poetic
3:46:45[Laughter]
3:46:47so what that means is i can go to any of
3:46:49the machines and i can interoperate i'm
3:46:50guaranteed to do that
3:46:52and then there are times however when
3:46:54i'm doing all the code on one machine
3:46:57that i can optimize i have the live
3:46:59objects i can do things etc
3:47:01and that by the way is what allows us to
3:47:02do the gui layering guise on top of
3:47:05powershell
3:47:06because we can have these nice high
3:47:09speed low latency
3:47:12activities if you tried to layer
3:47:14everything on top of a deserialized
3:47:16object
3:47:17you got a lot of recreating objects a
3:47:20lot of inefficiency
3:47:21right right yeah well guys this is our
3:47:24first hit into remoting so we did
3:47:27one-to-one
3:47:28we did one-to-many now we've got more
3:47:30remoting to do because
3:47:32we're just getting started with the
3:47:33remoting but now
3:47:35it's getting for that time for us to
3:47:38oh you know before we get into scripting
3:47:41i just oh no we gotta show more here
3:47:43no yeah i know there's a problem i have
3:47:46yeah
3:47:46this is cool but you know one of the
3:47:49problems i have
3:47:50i know a few of the problems
3:47:54one of the one of the things i run into
3:47:56is
3:47:58wouldn't it be cool if you know when i
3:48:01go on vacation i don't know about you
3:48:03but i like to go places with beaches
3:48:04oh yeah that have they have the the the
3:48:07little drinks with the little umbrellas
3:48:09in them
3:48:09and when i'm sitting on the beach the
3:48:11last thing that i'm gonna have is a
3:48:13laptop
3:48:14yeah right that's something not not cool
3:48:16not cool at all
3:48:17but things still do go wrong back at the
3:48:20office and so
3:48:21i am going to have a phone yep
3:48:25ah i see where you're going wouldn't it
3:48:29be
3:48:29you know it'd be so cool if i could
3:48:33maybe have powershell here
3:48:37and i could launch a script which we're
3:48:40going to be doing this afternoon or i
3:48:41could
3:48:42type in these commands and i could do
3:48:43all of this
3:48:45kind of cool stuff it would be so cool
3:48:48if i had powershell here or on a tablet
3:48:50if if only if only you had powershell
3:48:53version 3.
3:48:54if only you had powershell version three
3:48:56and
3:48:57at least one server 2012 box yeah it
3:49:00could be a vm
3:49:01but i want to show you something kind of
3:49:02cool have you picked up on the fact that
3:49:04we're big fans of powershell version
3:49:05three
3:49:06yeah we're huge fans of powershell v3 so
3:49:09guys i want you to watch something i'm
3:49:10actually going to take you through this
3:49:11is kind of a cute review not a cute
3:49:13review i can't believe i said the word
3:49:14cute this is a review
3:49:15over what we started off with today
3:49:18discovering
3:49:19and utilizing commandlets and in this
3:49:21case
3:49:22using a feature that i think is just
3:49:23wickedly awesome so here's what i'm
3:49:25going to do
3:49:26i'm going to use powershell remote or
3:49:28i'm going to enter a ps session to
3:49:30a server i have out there called pwa now
3:49:32this server
3:49:33doesn't really have anything on it it's
3:49:34just a generic server 2012
3:49:37box key is 2012. it could be a vm
3:49:40somewhere but it's
3:49:41got to be 2012. what i'm going to do is
3:49:44there's commandlet out there called get
3:49:46windows feature
3:49:48get windows feature is part of the
3:49:49server manager module
3:49:51what it does is it lists for you all of
3:49:54your roles and features for your server
3:49:56and if there are x's in it i know i love
3:49:58it when
3:49:59if there's an x that means it's
3:50:01installed if there's not an x
3:50:03it's not installed well i'm going to use
3:50:05this commandlet to
3:50:06see if there's a feature
3:50:10what features are available for
3:50:12powershell and in server 2012 we have
3:50:15something down here at the bottom called
3:50:17powershell web access i'm about to
3:50:19change
3:50:22the world as well and it's not me who
3:50:24i'm
3:50:25the only thing that i'm changing is i'm
3:50:26showing you how to set it up
3:50:28you're the one that changed the world so
3:50:30the team the team the team
3:50:31so yeah the team the team um so it's
3:50:34called windows powershell web access
3:50:36and this is pretty cool so i want to
3:50:38install this
3:50:39so we have this install windows feature
3:50:42commandlet that'll let me install
3:50:43windows powershell web
3:50:47access i've used git help i can
3:50:50the install windows feature will let me
3:50:52choose whatever thing i want to install
3:50:53and away it goes now here's what it's
3:50:55going to do
3:50:56[Music]
3:50:58it's going to install iis because this
3:51:02is going to be a web
3:51:03thing so it's going to install iis we
3:51:05have net 45 on here and its server 2012.
3:51:10when it gets this installed we'll also
3:51:12get a new module
3:51:13with some additional commands six
3:51:16additional command lines so what we're
3:51:17gonna do is use get help to find them
3:51:19and then use them because in like three
3:51:22steps i'm gonna have one of these
3:51:23coolest features in the world turned on
3:51:25so watch i'm gonna clear my screen this
3:51:27is just let me know they have my updates
3:51:29turned off which
3:51:30it's a vm right now it does but it was
3:51:31it exited with success
3:51:33no restart needed awesome so
3:51:36clear my screen and guys notice i'm
3:51:38doing this all on a different server
3:51:39right so
3:51:40how cool is that yeah i know this is
3:51:42totally wickedly cool
3:51:43so um i'm going to do github it's not
3:51:46your dad's server
3:51:47this is not your daddy i love that
3:51:50so it's it's called powershell web
3:51:52access so pswa a lot of us just refer to
3:51:55it as pwa powershell web access but
3:51:58pswa and you can see there's six
3:52:00commandlets by looking at the verbs you
3:52:02could probably figure out
3:52:03the first place i'm gonna go is to
3:52:05install
3:52:07a powershell web access application
3:52:09technically what's gonna happen is we're
3:52:11going to create
3:52:12a a a web application by default off of
3:52:16the default website
3:52:18when we installed iis now we didn't need
3:52:20to install it that happened for us
3:52:22automatically
3:52:23you can alter these defaults but i'm
3:52:25just going to take the defaults
3:52:26for right now now so install
3:52:30pswa and i'm going to
3:52:33you've got to use https for this because
3:52:36this is going to be something that you
3:52:37hit from
3:52:38anywhere in the world back to your home
3:52:42so we're going to need https you can't
3:52:44do this with http
3:52:46now if you don't have a good certificate
3:52:48to put on
3:52:49your web box right now for testing
3:52:52purposes
3:52:53they have this option of use a test
3:52:55certificate now i
3:52:56screened my screen freaked out a little
3:52:57bit but use a test certificate it's
3:52:59going to put on a temporary cert just
3:53:01remember this is not the cert that you
3:53:04want when you go to production so
3:53:07what's going to happen is is that it
3:53:08creates in iis terms an application pool
3:53:11for the web app creates the web app
3:53:13points the web app to where the files
3:53:15are and we're almost ready to go
3:53:19we just now have to tell it who's
3:53:20allowed to use this now
3:53:22this is going to be one of those rare do
3:53:24as i say not as i do
3:53:27and let me tell you why because i'm
3:53:29going to do get help again on
3:53:30on pswa we need to create
3:53:34who's allowed to use this and what
3:53:36they're allowed to go to when they use
3:53:38this
3:53:40so we need to add rules and you're going
3:53:41to want to add granular rules that make
3:53:43sense in other words
3:53:45is there a group of administrators that
3:53:46you want to be able to have remoting
3:53:48or to have powershell web access and
3:53:51what machine
3:53:52should they be allowed to get to or
3:53:55remote to when they use this
3:53:57you're going to want to keep control on
3:53:59this you're not going to want to do what
3:54:00i'm going to do just for easy sex so let
3:54:02me show you how to
3:54:04what you're looking for here so add
3:54:07a pswa uh authorization rule and let me
3:54:11just show you
3:54:13uh what computers do you want to be able
3:54:16to remote to
3:54:17so you can make this list you can create
3:54:18it as a computer group you also have
3:54:21another parameter you're going to need
3:54:22is either by
3:54:24user group or user name who's allowed to
3:54:27use this so you're going to want to fill
3:54:28out the username
3:54:29what computer and we're not going to get
3:54:31a chance to do
3:54:34different kinds of configurations but
3:54:36you can control
3:54:38through different configurations what
3:54:39command lets a person is allowed to use
3:54:41when they get there
3:54:42which is actually totally cool these
3:54:45three things
3:54:46you need to specify just be clear that's
3:54:48for things like
3:54:49hey i'm going to let um these people
3:54:51come into these machines
3:54:53and all they can do is read only
3:54:54operations
3:54:56like they can do gets they can't do sets
3:54:58and then
3:54:59this guy on these machines he can reboot
3:55:02the machine
3:55:03okay but he can't read data things like
3:55:06that and that's a really important point
3:55:08is that
3:55:08these users i've got administrators that
3:55:10have full capabilities but i got a guy
3:55:12who's a lot of reset passwords when he
3:55:14gets there
3:55:15that kind of stuff that you can control
3:55:17don't
3:55:18do what i'm about to do in real life if
3:55:20you're just testing on a vm that's fine
3:55:22but what i'm going to do is i'm for
3:55:23those three parameters i'm going to do
3:55:24star
3:55:25star star yeah i know i know that means
3:55:29everybody can do anything to everybody
3:55:30and it's just
3:55:31it's just lullable it's just yeah not
3:55:34not cool but
3:55:35for demonstration first summer of love
3:55:38the summer of
3:55:39love at this point
3:55:42i installed the feature i ins
3:55:45i i i installed the web app and i have
3:55:48now created a rule
3:55:51anarchy anarchy
3:55:55this is so so freaky cool guys this is
3:55:57um let me exit out of that machine
3:55:59this is so freaky cool that i'm going to
3:56:02uh this is start process i'm going to
3:56:04use the
3:56:04alias start and i'm going to start i
3:56:06explore
3:56:08with https and i'm going to go to that
3:56:11powershell web access box the box i just
3:56:13set up
3:56:16pwa and it's going to go to the default
3:56:19website and there's a web application
3:56:22underneath the default called pswa
3:56:25you can of course alter all this to make
3:56:27it cleaner but watch what happens
3:56:30secured site a matter of fact let me
3:56:32make this just a little bit
3:56:33zoomier sooner zoomier
3:56:37so this is the temporary certificate
3:56:39remember in real life when you go to
3:56:40production you're going to
3:56:41replace this continue the website
3:56:44it's going to come up it's going to ask
3:56:45me oh lookie it's going to ask for some
3:56:47credentials so
3:56:48doesn't it look like a outlook web
3:56:50access yeah we need to talk about that
3:56:55so here i'm going to put in my
3:56:56credentials watch
3:56:58and what computer do i want to remote to
3:57:01and work with
3:57:02well let's go mess with the domain
3:57:03controller i feel kind of froggy today
3:57:08get it oh do a hostname hostname show
3:57:10them where we are
3:57:11oh this is so cool it's powershell
3:57:15through a
3:57:15browser it's powershell through
3:57:19you made power shall work through but
3:57:23guys gals on the beach
3:57:26on the beach through any browser it's
3:57:29anything funny
3:57:30that it can be safari it can be
3:57:34ie it can be chrome it can be on any
3:57:37device a microsoft device a
3:57:39non-microsoft device
3:57:41your phone your tablet your laptop
3:57:44anywhere in the world
3:57:45you got powershell and i i want you to
3:57:47point out that not all these things have
3:57:49tab buttons when you use them
3:57:51but look i'll just even type a get
3:57:55dash serve lookie graphically they gave
3:57:58you a tab completion button
3:58:01i mean come on they thought this through
3:58:03this is so
3:58:04totally awesome now a lot of you right
3:58:06now are going wait a minute wait a
3:58:08minute wait a minute wait a minute wait
3:58:09a minute
3:58:10what about security stop it
3:58:13it's just like getting your email it's
3:58:15the same thing as getting your email if
3:58:17you have exchange
3:58:18you've got a casual out there probably
3:58:21in your middle tier
3:58:22protected by threat management gateway
3:58:23whatever you have it it's the same thing
3:58:26you can put the box right next to it
3:58:28it's the same
3:58:29thing so everybody says well this is
3:58:32going to be dangerous no more dangerous
3:58:34than you checking your email it's over
3:58:35https
3:58:37you control who has access to this you
3:58:39can even control what commandlets they
3:58:40can run
3:58:42this is one of the best tools and here's
3:58:44for a guy like me that's
3:58:46traveling all over the place i don't
3:58:49have a laptop
3:58:50necessarily with vpn to my network all
3:58:52the time sometimes the only thing i have
3:58:54is the tablet in my hand
3:58:56and i can run scripts which we need to
3:58:58do scripts
3:58:59and i can have access to powershell and
3:59:01remote to any box that i want to remote
3:59:03to dude you've undersold it
3:59:06i sold it i undersold it
3:59:09the security yeah absolutely no this is
3:59:12more secure than that
3:59:13okay why so let's see what we're
3:59:15comparing ourselves against
3:59:17so there you are and you got your laptop
3:59:19and you connect to your domain
3:59:20controller
3:59:21versus you're on your phone or this
3:59:24device of that device and you go https
3:59:27to a browser there to a to a website
3:59:30that then goes talks to the domain
3:59:32controller
3:59:33okay now on that machine that web server
3:59:37you're not setting that up so that
3:59:38people are surfing the net
3:59:40that web server that you go to on your
3:59:42laptop you're off there surfing your net
3:59:44you're at this new site that news site
3:59:46maybe some dodgy new dodgy sites dodgy
3:59:49sites
3:59:49yeah somebody's you're reading your
3:59:51email and people are saying oh you know
3:59:53click here
3:59:54for something wonderful and so that the
3:59:56risks of you know using that same box
3:59:59to manage your domain controller is
4:00:01pretty dodgy
4:00:02and so that's why the professional sites
4:00:05they set these things up called
4:00:06jump boxes they says okay look take your
4:00:09dodgy device
4:00:10whatever and then you go to this machine
4:00:13now this environment
4:00:14is safe stay safe you get to do one
4:00:17thing on this environment that is
4:00:18go to these other environments and you
4:00:20know i think that that that is such a
4:00:22great description because a lot of you
4:00:23guys probably have
4:00:24uh you might refer to them as bastion
4:00:26boxes question servers
4:00:28bastion servers where that's the whole
4:00:30point is that my laptop
4:00:32might be the wrong tool to be managing
4:00:34active directory with because
4:00:36of all of the weird things on it but
4:00:37this is a controlled server a controlled
4:00:40point that i'm going to that isn't going
4:00:41to have all that garbage and viruses and
4:00:44worms
4:00:44and crap on it and this becomes your
4:00:47bastion point or your bastion server
4:00:49this is awesome
4:00:50this is a huge time saver anywhere in
4:00:53the world and this way
4:00:54you know i heard this in in from
4:00:55microsoft i think it was in the year
4:00:572001
4:00:58we want to get to a place to where we
4:00:59can do we could be anywhere
4:01:02anytime on any device i think was the
4:01:04phrase and
4:01:05when this uh feature came out it was i
4:01:08can do powershell anywhere anytime any
4:01:09device
4:01:10you win so awesome feature before we
4:01:13wrap up promoting
4:01:14now we're going to do sessions in a
4:01:16little bit so okay but still i think
4:01:18there was a key
4:01:18point we didn't we didn't well
4:01:22you got the remote man what would you
4:01:24like to do
4:01:25let's leave this page yeah okay so go
4:01:27back to where you did the
4:01:28the uh and get the event log
4:01:32okay so uh you just want to get a value
4:01:34involved invoke command okay
4:01:36three machines oh you're gonna do it all
4:01:37over computer name
4:01:39by the way computer name if you want you
4:01:40can just type cn but anyway that's fine
4:01:42uh get log stop yeah
4:01:46get event log log name let's do
4:01:50system notice tab completion is working
4:01:52in the squigglies guys
4:01:54uh let's do newest three yeah yeah good
4:01:58character turn okay so here's the
4:02:01question
4:02:03why did we return objects
4:02:06like like that looks like text to me and
4:02:08that looks like what i wanted
4:02:10why didn't you just do that and the
4:02:12answer is
4:02:13because it's objects and objects are
4:02:15awesome so now what you can do is you
4:02:17can take that
4:02:18and do oh right go back just fine all
4:02:21right
4:02:22just run it okay okay so now what you
4:02:24can do is you can say
4:02:25uh pipe two sort
4:02:29time see here these aren't sorted by
4:02:32time
4:02:32so you get a three from this guy and
4:02:34then three from this guy and then three
4:02:35from those guys
4:02:36then say select are they sorry format
4:02:38table
4:02:39format table uh let's just say time and
4:02:43message
4:02:44property time and message
4:02:48oh time we need to do time um um it's
4:02:51time written
4:02:52yeah time written so uh let's do time
4:02:56written oops and i need to actually
4:02:59write it in here you guys get the idea
4:03:01but let me just get the and then maybe
4:03:02it's auto auto uh
4:03:05and oh this is getting better and then
4:03:07with the format commands guys the format
4:03:09commands are wonderful you should take a
4:03:10look at them
4:03:11format table one of my favorite ones
4:03:12because it has auto size
4:03:18is that crazy that is totally crazy so
4:03:20looking at that one liner
4:03:22what we're bringing back and this is
4:03:24this is a great thing is that we can
4:03:26then continue the pipeline and
4:03:27sort and select and still work with this
4:03:29exactly that's
4:03:30why the power of objects is so important
4:03:33because you know when you go do this
4:03:34stuff it's not about text
4:03:36it's about giving the objects and now
4:03:38all of a sudden like when i'm over there
4:03:40and i'm doing stuff i can manipulate the
4:03:41objects there and that's great
4:03:43but when i do remoting what i can do is
4:03:45i can get the objects from a very large
4:03:47set of machines
4:03:49bring them here and operate against the
4:03:51object so imagine
4:03:52imagine you say oh i got somebody and i
4:03:55need to give them
4:03:56i need to give them a share you can go
4:03:58out to all your file servers get the
4:04:00disk space from all your file servers
4:04:02as a collection of objects sorted by
4:04:04free space
4:04:05and then you can say give me the top
4:04:06three and then you can look at those and
4:04:08say
4:04:09yeah that's the one i want imagine how
4:04:10else you do it you go to this one find
4:04:12it write it down
4:04:13you go to that one write it down you go
4:04:15to that one how many of you guys are
4:04:16actually
4:04:17still sending people out to do that go
4:04:19check that file server see how much disk
4:04:21space it is put it into the spreadsheet
4:04:23so we can keep track of
4:04:24this as opposed to and there's several
4:04:26ways to do it what he's talking about
4:04:28but as opposed to
4:04:29um let's just use what is it get volume
4:04:32right is that is one of the new tests
4:04:35or get i think get volume will give you
4:04:37free space in science
4:04:38we're going to find out in a minute
4:04:39we're going to find out what's inside
4:04:40size remaining in size
4:04:42so yeah do it don't do it do it do it do
4:04:44it do it
4:04:46do it do it do it do it so let's do uh
4:04:49what do you want to do
4:04:50command and we'll do it to the way can
4:04:52we show them this short way
4:04:54this is this yeah yeah here's the short
4:04:56way yeah
4:04:57yeah i see icm and then and then the
4:05:00names
4:05:01or just do the names yeah because it's
4:05:02positional so dc s1
4:05:05s2 that's the short way and we want to
4:05:07do
4:05:08let's see get volume and pipe it to sort
4:05:11size remaining
4:05:13[Music]
4:05:14volume
4:05:16sort size
4:05:19i can't spell anymore it's a long day
4:05:23sort size remaining let's just try that
4:05:24see what we get
4:05:25[Music]
4:05:28oh god look look look the size remaining
4:05:31no wait wait wait no here's the thing
4:05:32go back up scroll up scroll up
4:05:35scroll up okay notice see you see notice
4:05:39how the formatting's no
4:05:40i want to show the previous previous one
4:05:42so notice here it just shows you
4:05:44drive letter to size but now you go
4:05:47scroll down
4:05:48notice we have ps computer name when the
4:05:51objects come back
4:05:52we add properties to it and we add where
4:05:56did this thing come from
4:05:57so that when i do this sort and then you
4:05:59go down at the bottom
4:06:01i can see okay well there's my volume
4:06:03but where did the volume come from and
4:06:04the answer is
4:06:05s2 that's right so and guys party on my
4:06:09friends
4:06:09oh and here's the thing that commandlet
4:06:11you can
4:06:12just say just show me the c drive you
4:06:15can sort and filter this out more where
4:06:16i just want to see the computer name and
4:06:18the size remaining
4:06:19and just get a nice short terse list
4:06:22then
4:06:23export to csv you got your report done
4:06:25and you did it on as many computers as
4:06:27you wanted to
4:06:28in seconds you show them select last
4:06:32yeah yeah yeah so here this might have
4:06:34been like if i'd done this to like lots
4:06:36of machines and there were file services
4:06:37and lots of stuff on it
4:06:38this would be pretty big and you don't
4:06:39want to mess with that right so what you
4:06:41do is you say select minus last
4:06:43let's pick the last three three
4:06:47and what it'll do is give you the last
4:06:49three just exactly what you think it
4:06:51would do boom
4:06:51boom there's the last three so we can
4:06:54show rocks
4:06:55at powershell so rocks we have first we
4:06:57have last there's
4:06:58all kinds of ways this is the importance
4:07:00of taking a look at those help files
4:07:02skip exactly so make sure you look
4:07:04inside these help files because
4:07:06you can do it it's not something well i
4:07:08can't figure out how to do it
4:07:09you don't need bizarre long links of
4:07:11code you need to look at the help files
4:07:13they've really thought this stuff
4:07:15through
4:07:15and if you get stuck powershell.org
4:07:18and ask on the forum yeah lots of really
4:07:21helpful people out there
4:07:22and just as a side note i it's it's it's
4:07:25fascinating that
4:07:26how strong the powershell community is
4:07:29you guys have noticed
4:07:30this is not necessarily the easiest tool
4:07:32in the world for you to learn it's the
4:07:33most powerful one in your toolbox but
4:07:35it's not an easy tool to learn because
4:07:37you're just staring at a prompt and now
4:07:39what do i do
4:07:40we've all gone through this and so the
4:07:42powershell community
4:07:44is so strong they want to help you so
4:07:46avail yourself of those resources and
4:07:48i'll give you some more here in a little
4:07:50bit
4:07:50yeah can you riff on that a second yeah
4:07:51so here's the thing you know we found as
4:07:54we were rolling out powershell that the
4:07:55community just flourished and it's like
4:07:57wow and people are having a blast
4:07:59now here's the interesting thing turns
4:08:01out that this this like hurts the
4:08:03community
4:08:04no seriously it hurts the community why
4:08:06and so and we noticed this because
4:08:07at some point we're putting things
4:08:08together and everyone like hey did you
4:08:10see what bruce did no what did bruce do
4:08:12we all run into bruce's office
4:08:14and he shows what he does he's like oh
4:08:16man that's awesome can you send that to
4:08:17me he sends it to me and i'm doing it
4:08:19and then i change it and they're like oh
4:08:21check out what jeffrey did and everybody
4:08:22comes running
4:08:23and we were just having a blast with
4:08:24this and when lois we thought we said we
4:08:26talked about this a little last night we
4:08:28said
4:08:28boy we're really having fun here and
4:08:30like it used to
4:08:31computers always used to be fun and then
4:08:33for some point
4:08:34they stopped being fun it just seemed
4:08:36like it was a job
4:08:38it became mundane mundane and i think it
4:08:40was because of this damn thing
4:08:42the mouse right and so here's the idea
4:08:44like like i never
4:08:46i never never never say hey come on guy
4:08:49did you
4:08:49check to see the way jason was clicking
4:08:51that mouse my god
4:08:53you were such a clever guy did you see
4:08:55the snap on that thing see i love you
4:08:57man because man i work on my mouse moves
4:08:59and
4:09:00so it's yeah well no that's the point so
4:09:02when when i see you
4:09:03program when you script and you write
4:09:05together as command line
4:09:07i see how you think and i'm able to say
4:09:09wow that's really clever that's really
4:09:11neat
4:09:11and you're able to then then i say oh
4:09:14can i have that
4:09:15right and you give it to me and all of a
4:09:16sudden you've helped me
4:09:18like you click let's say you're a god at
4:09:20clicking that mouse right
4:09:22how can you help me like step back and
4:09:24be impressed i guess
4:09:29right but with a script you can help me
4:09:30and i can take it and i've modified it
4:09:32meets my needs and i look great to my
4:09:34boss
4:09:34and all of a sudden you know what two
4:09:35things one is you feel good because you
4:09:37help me
4:09:38two i feel good i have a debt of
4:09:40gratitude to you i mean thank you very
4:09:41much
4:09:42that's very awesome and you buy your
4:09:44beer or something like that
4:09:45and also i say hey you know what i
4:09:47should help other people too
4:09:48so really you should help other people
4:09:50first be aware
4:09:52there's lots of people in the community
4:09:53out there more than willing to help you
4:09:55should not be sitting
4:09:57you know suffering in silence no no if
4:09:59you're confused or anything
4:10:01i guarantee you nobody's going to be and
4:10:04you should not be embarrassed by any of
4:10:05your questions people aren't going to
4:10:07make fun of you
4:10:08that's not going to happen the barrier
4:10:10for you asking a question should be
4:10:12extraordinarily low just
4:10:14ask the question in a form in twitter
4:10:16twitter
4:10:17very useful place as well just ask that
4:10:19question people will help you
4:10:20and it turns out then when and then you
4:10:23should participate
4:10:24you should say hey i found this clever
4:10:26way to do things you should blog things
4:10:28and here's a great thing right
4:10:29so you might know i've been doing this
4:10:31powershell thing for a little while now
4:10:33i blog things i blog things and say oh
4:10:35here's what i do and people will say
4:10:37jeez why do you do it that way why
4:10:39didn't you do it this way i was like
4:10:40i didn't know you could do it that way
4:10:42and so the community is teaching me how
4:10:44to do things
4:10:45honestly it's just a wonderful thing and
4:10:47i have to say it's
4:10:48it's truly amazing and and remember when
4:10:51computers were fun when it wasn't i need
4:10:52to reset a bunch of passwords and you
4:10:54just sat there and went like
4:10:55this where now you're actually going oh
4:10:57i'm going to figure out how to reset
4:10:59these passwords i'm going to figure out
4:11:00how to do xyz
4:11:02awesome and now i'm going to automate it
4:11:05so i never have to do it again but it
4:11:07was fun figuring out the problem it used
4:11:09to be
4:11:09fun solving the problem and powershell's
4:11:13brought that back and the community is
4:11:14really strong with that
4:11:16folks so here's what we're going to do
4:11:17is let me show you the um just
4:11:19to let you know that with all of this
4:11:20stuff we did in remoting is in the
4:11:22slides
4:11:23and i'm just going to go through these
4:11:25real quick but it's not the end yet of
4:11:26remoting we've got some more stuff to do
4:11:28but we want to start some automation and
4:11:29some scripting to come up
4:11:32and so um we're going to kind of get
4:11:33started on this and before we take a
4:11:35break so
4:11:36if you have questions or comments please
4:11:38make sure you're jumping out there and
4:11:39we're going to come back to remoting in
4:11:41just a second
4:11:42but before we take a break let's get
4:11:44started on this concept
4:11:46of automation and to do that
4:11:49we need to start to talk about things
4:11:51like
4:11:52security because we're going to talk
4:11:54about scripting now
4:11:55and so we're going to take the commands
4:11:57that you're building as one-liners and
4:11:59and so forth
4:12:00and we're going to take those commands
4:12:01and now automate them by putting them
4:12:03into a script and just telling the
4:12:05script to run them for us
4:12:07no major deal yet it's pretty
4:12:09straightforward but to run a script
4:12:11requires some special security so
4:12:13we're gonna talk about security we're
4:12:14gonna talk about variables a place to
4:12:16store your stuff
4:12:17maybe a little bit with quotes and then
4:12:19we'll start getting into the automation
4:12:20so the first thing off
4:12:22is and by the way that's a picture of me
4:12:24right there the big guy in there
4:12:26on the next screen usually people say
4:12:28that's the picture of me but that's it
4:12:30no oh no guys in the background yep
4:12:32that's it
4:12:34so powershell is secured by default for
4:12:37several different with several different
4:12:40ways we had some problems in the past
4:12:41with
4:12:42like vbscript you double click on it it
4:12:44runs oh god
4:12:45yeah talk a little bit about what
4:12:47powershell does for us
4:12:49yeah so okay again remember it's secure
4:12:51by default you know we did this
4:12:52secure secure secure so when you double
4:12:54click so what happened if you weren't
4:12:56around then uh people would came in one
4:12:59morning
4:13:00and they got a mail i love you and
4:13:02they're like
4:13:03oh well i feel i feel special i've got a
4:13:05secret admirer
4:13:06and even even the people like i bet
4:13:08that's not true
4:13:10but it might be right so i want to find
4:13:12out why not who loves me
4:13:14click click and and then it would run
4:13:17you click on this thing and it would run
4:13:18and guess what
4:13:19bad things happen bad things anybody
4:13:21who's like giving you something free
4:13:23are promising to grow or shrink your
4:13:24body parts with just with money
4:13:27just doesn't work okay and so too
4:13:29somebody sends you love
4:13:30don't click on that stuff anyway so with
4:13:32powershell somebody sends you that
4:13:34and you double click on it it brings up
4:13:36it in the editor it doesn't run it
4:13:38it doesn't run it that is the key so
4:13:42let me do a quick demonstration of that
4:13:43let's uh let's just make a really quick
4:13:45script and guys
4:13:46do we will get cooler than this but i'm
4:13:48going to make a really quick script and
4:13:50i've been doing this git service bits
4:13:51thing all morning i'm getting sick and
4:13:53tired of typing this in
4:13:54and i'm going to make sure that it works
4:13:56it works i'm going to take this right
4:13:57now and i'm
4:13:59copying it and i'm going to start up
4:14:01notepad
4:14:02and i'm going to yeah we're using
4:14:04notepad right now don't worry we're
4:14:06going to get to the ise i'm going to
4:14:07paste it in there
4:14:08file save as and here's the magic to
4:14:12making a script
4:14:13well let me put it on my desktop so we
4:14:14can see it is what do you want to call
4:14:16this script let's
4:14:17call it i love you i love you
4:14:21and uh let's uh dot ps1
4:14:25uh ps1 and i don't actually want to put
4:14:28on my desktop i'm going to put it under
4:14:30my scripts folder here so i can get to
4:14:32it and
4:14:34there's a scripts folder right there i
4:14:36love you ps1 you gotta get rid of the
4:14:37text
4:14:38i gotta hear oh yeah yeah yeah files
4:14:41all files and save stick with me guy
4:14:44i'll help you out
4:14:47so i i've got a script what i want you
4:14:49to see is is yes i'm going to show you
4:14:51this graphically first because i want to
4:14:53see what
4:14:53what jeffrey just said i'm going to go
4:14:55out here and if somebody were to send
4:14:57this to me
4:14:58i love you ps1 and i'm going to double
4:15:01click it
4:15:02see brings it up in notepad or whatever
4:15:05editor you're
4:15:06you're you're they've set for it then
4:15:08what they didn't look
4:15:09they didn't actually love me it didn't
4:15:10execute my script now this is a good
4:15:12thing
4:15:12for so many reasons as you guys already
4:15:14know you don't want scripts to
4:15:15automatically execute but i want to
4:15:17bring something up
4:15:18a lot of the security that we're going
4:15:19to be talking about and the next thing
4:15:21which is execution policy which we're
4:15:23going to do before we go and break um
4:15:25i need to tell you that this is this
4:15:28security
4:15:29is is is designed to take an
4:15:31unintentional
4:15:32user to stop them from doing
4:15:34unintentionally malicious things in
4:15:36other words
4:15:37i want you to think about i downloaded a
4:15:39script i double click on it i didn't
4:15:41want it to run i just i wanted to look
4:15:42at it
4:15:44we this helps you now if you
4:15:47are a power user that wants to be
4:15:50malicious
4:15:51can we change this well yeah
4:15:54i mean power i mean yeah i can i know
4:15:57how to change the association of the ps1
4:16:00to make it actually execute that's just
4:16:03not a good idea
4:16:04don't do that the point is is we're not
4:16:06going to stop you from doing that but
4:16:08this helps you for making foolish
4:16:10mistakes like this
4:16:11so let's try to execute this script and
4:16:13watch what happens
4:16:15there's another security feature the
4:16:17whole path thing
4:16:18you you make us type in the path yeah
4:16:20well first just try and type it
4:16:22so c colon scripts and i was i love you
4:16:26cd to there oh okay
4:16:30and then just type i love you i love
4:16:33you i love you i no that's not going to
4:16:36work
4:16:37well i love ip i love ip i love ip i p
4:16:39therefore i am there we go i love you
4:16:41what what what what what
4:16:44says no no no no no not recognized as
4:16:48the name of a commandlet a function or a
4:16:50script
4:16:50file check the spelling well look at the
4:16:54suggestion have you ever known someone
4:16:55did you notice that the command i love
4:16:57you was not found but
4:16:59does exist in the current location you
4:17:01never know
4:17:02i never noticed that tricky tricky so
4:17:04now that's just going to confuse me more
4:17:06because it's going to say
4:17:07oh but then it actually tells me how to
4:17:09solve it yeah
4:17:10type dot slash now here's the reason why
4:17:13this is what's called a you know kind of
4:17:14a trolling attack so what would happen
4:17:17is
4:17:17and this is the old-time unix problem
4:17:20your admin
4:17:21and your cd to somewhere and you say
4:17:22print working directory
4:17:24and a bad guy would go in that directory
4:17:26and they'd put something called
4:17:28print working right directory they would
4:17:29rename iloveyou.vbs to print working
4:17:31directory directory
4:17:32so you cd there you do print working
4:17:34directory you run that code
4:17:37and so and bad things would happen and
4:17:39so what we said was no no
4:17:41if you want to run something in the
4:17:42current directory you have to be
4:17:44clear that that's what you want to do
4:17:46we're very clear
4:17:47very big on intentionality you have to
4:17:49tell me that that's what you want
4:17:51otherwise no i remember uh root kits
4:17:54used to come in there was a dir
4:17:55root kit and you would go dir and you
4:17:58were running the root kit
4:18:01yeah bad bad so what this prevents from
4:18:03is let me show you this two ways one is
4:18:05i could try to run the script by typing
4:18:07in the full path to the script
4:18:09i love you or i can be in the current
4:18:13directory and let me show you that one
4:18:14if i'm in the current directory with the
4:18:15script and try to run it
4:18:19it's dot slash i love you ps1
4:18:22and that's what that general message at
4:18:24the bottom told you to do is because it
4:18:26saw it there
4:18:27this will run my script oh
4:18:30no i'm a failure i'm a failure in life
4:18:32because it found it but it
4:18:34says it can't be loaded because the
4:18:36running of scripts is disabled on this
4:18:39system
4:18:39for more information in other words
4:18:41you're not allowed to run
4:18:42scripts and when we come back from break
4:18:45we're going to show you
4:18:47why you're not allowed to run scripts
4:18:49and then how to change that so
4:18:51we'll see you guys in 10 minutes yeah 10
4:18:53minutes cheers
4:19:12[Music]
4:19:20oh now see i was talking for like a
4:19:22minute and a half and they didn't turn
4:19:24the cameras on
4:19:25so so back to what we were
4:19:29back to what we were doing there they
4:19:31are where are you back
4:19:32there where have you been um so here's
4:19:35the deal
4:19:36we need to work with the execution
4:19:37policy now i just want you to take a
4:19:38quick look at this slide because it it
4:19:40lists the execution policy
4:19:42for us kind of quick now we have a
4:19:44couple of commandlets that'll let us
4:19:45work with the execution policy and by
4:19:47default
4:19:48you are restricted in other words no
4:19:51scripty allowed to run
4:19:52now interactive only yeah and i just
4:19:54want to point out
4:19:56that see the word under here called
4:19:58unrestricted
4:19:59can we just right now kind of put into
4:20:01our heads that that's not an option for
4:20:03you to set
4:20:04it did it with bypass bypass because
4:20:06there bypass like
4:20:08yeah but unrestricted and bypass so can
4:20:11you kind of i know you i don't want you
4:20:13drawing on your computers but can you
4:20:14just kind of cross those off
4:20:16restricted unrestricted well restricted
4:20:18is good for
4:20:19but no crossover unrestricted bypass can
4:20:22we focus on the two that we really want
4:20:24you to focus on which is
4:20:26remote signed and all signed
4:20:30so do you want to talk about the the the
4:20:32what is this signed
4:20:33thing in the first place that we're
4:20:35talking about so basically basically
4:20:36digital signatures now in the past like
4:20:38vbscript had this
4:20:40that was really bad stuff all it did was
4:20:41said hey if
4:20:43a script is digitally signed i'll run it
4:20:45not
4:20:46digitally signed by someone i trust
4:20:47trust yeah so
4:20:49we took a different approach we said it
4:20:51has to be digitally signed
4:20:52and you have to trust them so before we
4:20:55talk about the difference between
4:20:56all signed and remote signed can you
4:20:58show us what's what it's like to sign a
4:21:00script
4:21:00okay so let me first go i i've created a
4:21:03new
4:21:04a self-signed certificate and if you
4:21:06ever wonder about that you just say new
4:21:08self signed certificate you can go
4:21:12create your own
4:21:13i've already created some and what i do
4:21:15is they're in the cert drive not if
4:21:17we've talked about this there are these
4:21:18things called providers
4:21:19get ps drive okay and you'll see the
4:21:23traditional drives like the c
4:21:24drive that we've been showing but
4:21:26there's a certificate drive oh
4:21:28so what i can do is i can do a dir of
4:21:30the certificate drive and i do tab
4:21:32completion here
4:21:33sorry current user and what i'm doing is
4:21:35i'm looking for a code signing search so
4:21:37the interesting thing is when i'm in the
4:21:38certificate drive
4:21:39i can do things like well i can do
4:21:41recurse on any drive of course
4:21:43but i can say give me the code signing
4:21:45certs
4:21:46how strange and then what i'm going to
4:21:48do is i'm going to say ov
4:21:49or output put variable
4:21:53a okay so what that did was it got me
4:21:57did a recursive search found me my code
4:21:59signing certs
4:22:00i now put them in dollar sign a and then
4:22:03what i'm going to say is dollar sign
4:22:04cert equals dollar sign a zero so now
4:22:06i've got a particular code signing cert
4:22:08okay so now let's see let's get my
4:22:11execution policy
4:22:13get execution policy and you see it's
4:22:16remote sign here i'm going to change
4:22:18that to
4:22:21set execution policy equals
4:22:25all signed okay oops sorry
4:22:29a equals what am i doing i'm making an
4:22:30idiot set execution all signed
4:22:33it says yep do it now here i am and i
4:22:36have this
4:22:36test script oop let me just edit that
4:22:39test script
4:22:43let me just get rid of this because i
4:22:44already signed it that's not right
4:22:49don't you see that
4:22:52okay so there's my test script
4:22:56right and i go and i run it
4:23:00it says no you can't do it because
4:23:03uh it's not digitally signed okay
4:23:06because you went to all signed which
4:23:07means
4:23:08everything must be signed talk about
4:23:10remote signed in a second but everything
4:23:12must be signed
4:23:12so now i say well i'd like to sign it
4:23:14because i trust this i first
4:23:16don't sign stuff you haven't understood
4:23:18like sign it saying
4:23:20sign it is remember i said earlier like
4:23:22i take my badge out i put it on the
4:23:24table and i say
4:23:25i guarantee is it going to work when
4:23:27you're digitally signing something
4:23:28you're taking your badge out you're
4:23:30putting on the table and say anything
4:23:31wrong
4:23:32take my badge okay so be careful so you
4:23:35probably want to take a look at the
4:23:36script you're going to smell probably
4:23:37yeah i take a look then i said i'm
4:23:41so you want to set the auth
4:23:45authentication code signature
4:23:48of i give my cert and my dollar sign
4:23:51cert and
4:23:55the file pack yeah okay now notice
4:23:59now when i do this test.ps1
4:24:03here i'll cat it cat test
4:24:08oh look at that thing look at that
4:24:11wow yeah so now i mean that is a
4:24:14that's a big beast so now if your script
4:24:17actually did something harmful
4:24:18we know who you are and we can hunt you
4:24:20down yes
4:24:21except it's a self-signing script right
4:24:23so so yeah but yes we can
4:24:25now here's the deal dot slash test now
4:24:27watch what happens
4:24:29just because it's signed doesn't mean
4:24:30i'll run it okay
4:24:32so we'll say hey uh do you want to run
4:24:34this thing
4:24:35and you can say hey never run it
4:24:38uh don't run it run it once i'm gonna
4:24:40say run it once
4:24:42okay now if i said always run it it
4:24:45would have then taken that certificate
4:24:46and said
4:24:47i always trust stuff from this guy from
4:24:49this certificate yeah and then you can
4:24:51run it
4:24:51now here you want to see something crazy
4:24:53yeah yeah
4:24:54i told you we pay attention to the
4:24:56security stuff right
4:24:58i told you that okay so now imagine
4:25:01imagine i go and i say
4:25:02um okay so we say let's say
4:25:06now just because it's signed i can run
4:25:09it always so i can say set
4:25:11execution policy and i'll say
4:25:14um uh the remote signed
4:25:20okay so fine now
4:25:23now i can go and i can run this thing it
4:25:26just runs
4:25:27okay just run but now watch this now
4:25:29again what did i say
4:25:31when i get a script from the internet
4:25:32you don't want to just run it you want
4:25:34to examine it
4:25:35okay so imagine i do this thing and i
4:25:38say
4:25:38hey let let me look at this thing and i
4:25:40see that and i say hey you know what
4:25:42that's safe
4:25:42i'm just going to run it right let me
4:25:44take a look is it safe
4:25:46it's got a signature it looks and the
4:25:48code looks safe yeah okay
4:25:49okay but wait what if i do this
4:26:00oh that's not safe that's not safe now
4:26:03now let's save that that's that's kind
4:26:04of mean so
4:26:06let's make sure we do this so now again
4:26:09you come here and you have this script
4:26:11yeah yeah
4:26:13that that that's mean man but you say
4:26:15hey you evaluate it
4:26:16right i'm evaluating and it looks good
4:26:18at the top right yeah but what if
4:26:20down here or somewhere in there is there
4:26:22everybody yeah
4:26:24well let's run it what do you think
4:26:26should i run it
4:26:27yeah let's let's no no because you're
4:26:30going to run it it's going to rest no i
4:26:31checked it out i read it it looked fine
4:26:33look look all right it looks fine it's
4:26:36fine
4:26:36okay run it i mean it looks great you
4:26:38know what could possibly go wrong nobody
4:26:40would have
4:26:40stuck anything in
4:26:45so check this out executable code
4:26:48found in the signature block
4:26:51so we're aware of this threat we're rare
4:26:54that
4:26:54that people how they're going to
4:26:55evaluate things they're going to look at
4:26:57things we're going to see the signature
4:26:58block
4:26:59they're just going to say yeah yeah yeah
4:27:01and so we look for people
4:27:03uh sneaking in bad code and so we
4:27:06protect you from that and say no we're
4:27:07not running that crap
4:27:09and we even tell you where it is line
4:27:1093.
4:27:12oh i just got saved from this horrible
4:27:15thing no
4:27:15that's totally awesome so i so here's
4:27:18here
4:27:20all signed versus remote sign all sign
4:27:22means every script
4:27:23that you download and that you create
4:27:25locally
4:27:26needs to be signed and just to let you
4:27:28know and i'm going to type this on my
4:27:29screen
4:27:30there is a help file about underscore
4:27:32signing that will basically take you
4:27:33through
4:27:34everything that jeffrey just did to sign
4:27:37a script
4:27:38but let's talk about something for a
4:27:40second remote signed
4:27:42a lot of you right now it's going to be
4:27:44easier for you to start off with remote
4:27:45signed here's what this means anything
4:27:47you download
4:27:48like from the internet needs to be
4:27:50signed do you guys know that
4:27:52we know what you download from the
4:27:54internet
4:27:57okay i'm just saying a bunch of guys
4:27:59just went
4:28:00i got to delete this uh nah there's
4:28:05there was a i can't remember what was
4:28:06put in mark of the web was put in
4:28:09so that things got tagged if they got
4:28:11downloaded from the internet this is to
4:28:12protect you this is a feature
4:28:14and they tagged it so that it overwrote
4:28:16rootkits well powershell knows this and
4:28:18powershell knows
4:28:20that if you downloaded it from the
4:28:21internet if you're set to remote signed
4:28:24there needs to be a signature on there
4:28:26but if you make the script locally there
4:28:29doesn't have to be a signature on it so
4:28:31a lot of folks
4:28:32will set their policy and this is okay
4:28:34to start with to remote sign
4:28:36just because it's easier to get started
4:28:38with
4:28:39[Music]
4:28:40which that's fine but as soon as you
4:28:42possibly can you really want to remove
4:28:44go to all sign because i want you to
4:28:46think about this at some point you're
4:28:48going to want to have this
4:28:49execution policy where you can run
4:28:50scripts in other places
4:28:52and it'd be nice to be able to control
4:28:55this through
4:28:56that the scripts have to be signed
4:28:57imagine what your users might do if they
4:29:00figure out how to turn on scripting
4:29:01policy
4:29:02they might want to download a script if
4:29:05you set this through
4:29:06a group policy then you're going to be
4:29:09able to help control what could be some
4:29:11possible issues of users trying to do
4:29:13weird things
4:29:14so this is actually really important
4:29:16remote signs good to start with all
4:29:17signs
4:29:18is really the best to get to watch what
4:29:21happens now and you've seen it with
4:29:22jeffrey now that
4:29:23i have an execution policy that works i
4:29:26can try to run my script
4:29:27and i forgot what my script was i love
4:29:30ups one and lo and beholds
4:29:32there it goes now so script script
4:29:35execution policy need to turn it on yeah
4:29:39let me talk about the latest version
4:29:40latest version of windows
4:29:42top secret top secret topsy we're
4:29:44disclosing we're going to bring you into
4:29:47the circle of trust
4:29:50so the next version of windows server
4:29:52let's say windows server 2012 r2
4:29:55we change the default execution policy
4:29:58to be
4:29:58remote signed by default which is
4:30:00awesome because that way you don't have
4:30:02to run around to your servers
4:30:03or issue out a group policy to get this
4:30:05because you need your servers
4:30:07to have an execution policy so when
4:30:09modules load and you want to shoot you
4:30:11want to load scripts from all that kind
4:30:12of stuff
4:30:13it makes life a lot easier so server
4:30:152012 r2
4:30:17right is when it ships we'll have the
4:30:19new poli which is amazing to
4:30:21have that set yeah by the way a number
4:30:22of people let me just clarify one thing
4:30:24we're not going to get into the details
4:30:25of the security but i will just point
4:30:27out that even if you're
4:30:28uh if you have like uh execution policy
4:30:31to be
4:30:32you know uh unrestricted whatever an
4:30:34interactive user basically an
4:30:36interactive user can do
4:30:37anything and they can bypass that that
4:30:41don't worry about that that is not a
4:30:43security violation that's not a hole
4:30:45there's actually a long explanation for
4:30:47that we won't get into it here because
4:30:48it's not that interesting
4:30:49but just don't freak out if somebody has
4:30:51access to a terminal
4:30:52i mean basically here's the thought if
4:30:54they have access to a terminal uh
4:30:56they can uh uh create programs compile
4:30:59those programs and run it which means
4:31:01they can do anything
4:31:02so at this point it's it's not a
4:31:04security remember the old the old thing
4:31:06of physical access right
4:31:07physical access so um guys we want to do
4:31:10a couple of things to set us up for some
4:31:11scripting one of the things that we want
4:31:13to do here oh this is
4:31:14we're going to start doing first of all
4:31:15variables now uh
4:31:17we've already been using them believe it
4:31:19or not i just want to show you that
4:31:21um watch i'm going to show you there's a
4:31:22whole bunch of commandlets so i'm
4:31:24thinking to myself
4:31:25how would i find if powershell had any
4:31:27commandlets to help me with variables
4:31:29i can do this variable and
4:31:32oh looky there's a whole bunch of clear
4:31:34variable get variable new variable
4:31:36remove variable set
4:31:38stop looking at the screen we're not
4:31:40going to use any of them we don't need
4:31:41to
4:31:42powershell makes working with variables
4:31:44really easy we don't necessarily need
4:31:45these commandlets
4:31:46so let me show you how easy it is to
4:31:48make a variable um
4:31:50watch variables um have a dollar sign
4:31:53and
4:31:54there's a lot of reasons for the use of
4:31:55this dollar sign we're not going to get
4:31:57a chance to go into
4:31:58how the parsing engine reads all of this
4:32:00but this is not the name
4:32:01or part of the name of the variable it
4:32:04tells powershell hey
4:32:05something's about to happen and if it's
4:32:06alphanumeric after it
4:32:08my var this is going to be a variable
4:32:11if you want to set this variable equal
4:32:12to something equals
4:32:15hello thank you thank you no commandlets
4:32:19required i just created variable
4:32:20totally totally awesome you want to see
4:32:22what's inside of a variable
4:32:24myvar but variables are awesomely cool
4:32:27because
4:32:28variables don't just take text they
4:32:30don't just take integers
4:32:32watch my var
4:32:35equals get service
4:32:40bets guess what's in my var right now
4:32:43guess what's in my bar wait a minute let
4:32:45me show you this is called my
4:32:46bar
4:32:50wait wait wait wait wait watch watch
4:32:53watch
4:32:53get member lookie look look look
4:32:56look look what's in my bar i got a
4:32:59service controller object in there
4:33:01it's not just text guys it's it's
4:33:03service controller object so
4:33:04i want you to notice something we
4:33:06haven't talked much about running
4:33:07methods but
4:33:08all these properties and look there's a
4:33:10couple of methods here there's a start
4:33:12and a stop method
4:33:14i have an idea i wonder if i could use
4:33:16this
4:33:17dot notation that you started using
4:33:20my var dot let's see a property status
4:33:24oh it's running and i wonder if i could
4:33:26get it to run
4:33:27a method like stop
4:33:34now i know you're all saying well prove
4:33:35it prove it prove it all right well
4:33:37one little thing is i'm going to do my
4:33:39var status but you're going to say oh
4:33:40so you didn't work no no no no no if we
4:33:43refreshed
4:33:44everything that existed in windows
4:33:46constantly
4:33:47oh my god so there's a method to help us
4:33:49refresh this so refresh
4:33:53and now look at the status boom
4:33:56totally awesome vars make your life
4:33:59much easier and of course with scripting
4:34:02bars become very important now there's a
4:34:04lot to do with vars and there's a lot of
4:34:06tips and tricks with working with bars
4:34:09um can you tell one thing oh absolutely
4:34:11so snap to mine
4:34:13so here's the thing you i think it's
4:34:15because it's a jump start and it's
4:34:17tutorial
4:34:17um like why do we have this dollar sign
4:34:20some people like i hate the dollar sign
4:34:21blah blah blah
4:34:22well here's why so when we say dollar
4:34:24sign my var
4:34:27equals get service
4:34:31service bits okay right just works right
4:34:34but what happens if i do this
4:34:37right some people like i don't like
4:34:39dollar signs okay fine what happens
4:34:42and the answer is an error but look at
4:34:43the error the term myvar
4:34:46is not recognized as the name of a
4:34:48commandlet
4:34:50okay so so when you start a command
4:34:53when you start a line with a name
4:34:56the question is well is it a variable or
4:34:58is it a command line right
4:34:59and we have to know and so that's why we
4:35:02have dollar signs in front of our
4:35:03variables because you have to know
4:35:05and this remember i talked about the
4:35:06struggle between interactive programming
4:35:09and
4:35:09and systems programming this was the key
4:35:11thing that
4:35:12interactive commands uh have require a
4:35:15special syntax
4:35:16in programs you're not running things
4:35:18out of the file system
4:35:19right right you're running you know apis
4:35:22and such
4:35:23in an interactive shell you run things
4:35:24out of the command so so when you type
4:35:26ping you just want ping to work you
4:35:28don't want to have to say
4:35:30oh well i want to do something special
4:35:31for ping
4:35:33so that's why you just type ping
4:35:36right but if you want dollar sign ping
4:35:39to be
4:35:40x you type dollar sign ping that's why
4:35:44we have the dollar sign that's it
4:35:45no and that's actually very important
4:35:47everybody's always asking about the
4:35:48dollar sign so when you're working with
4:35:49vars
4:35:50you got to have the dollar sign now a
4:35:52couple of little things a little uh
4:35:54um oh let's let's play with since we're
4:35:57getting ready for scripting we're going
4:35:58to take this concept of using a var and
4:36:00try something here let's uh watch
4:36:02this let's see uh there's a commandlet
4:36:04called read host
4:36:06it'll actually read things from the host
4:36:10the host so let me see dollar sign var
4:36:13equals
4:36:13read host so whatever we read in is
4:36:16going to get stored in the variable and
4:36:17i'm gonna say
4:36:18enter a computer name now guys you can
4:36:21imagine
4:36:22this in a script already because watch
4:36:24what happens i'm gonna strike enter
4:36:25comes up says enter a computer name
4:36:26okay i'll enter one now what's stored in
4:36:30var right now
4:36:32is that computer name you can now use
4:36:34that variable
4:36:35which is where we're going with all this
4:36:37get service
4:36:38name bits dash computer name dollar sign
4:36:41var
4:36:42guess where we're going to go get that
4:36:44information from now
4:36:45so we're going out to that that that
4:36:48that the dc in this case
4:36:50so we're storing stuff in the vars and
4:36:52then we're going to use those vars
4:36:53in our commands with our parameters as
4:36:55part of the arguments
4:36:57this is going to start us making better
4:36:59scripts and being able to do automation
4:37:01a little bit better
4:37:03but i want to show you just a couple of
4:37:04quick things because you're going to
4:37:06hear this and you're going to see this a
4:37:07lot and i just have to throw it out
4:37:09because
4:37:10i'm kind of i want to ask about it so
4:37:13dollar sign var if i do this it just
4:37:15prints it to the screen but we actually
4:37:16have a commandlet
4:37:18that were is designed to print things to
4:37:20the screen for you
4:37:21um let's do uh write host real quick
4:37:24you're going to see this a lot right
4:37:25host dollar sign var
4:37:27same result except right host has things
4:37:29like foreground color
4:37:30red background color green
4:37:34yay you can play with the colors
4:37:36everybody just got really excited
4:37:37because now they can play with colors
4:37:38yeah start playing with colors um we
4:37:42have ways for you to play with colors
4:37:43and i
4:37:44you probably have heard the phrase every
4:37:47time and
4:37:47every time you use write host
4:37:50god kills a puppy
4:37:53so don't use right house no i i want to
4:37:56be straight with you
4:37:57there are times to use write host it's
4:37:59just i want you to see
4:38:00what you're doing and when you start
4:38:02scripting this really starts to matter
4:38:04yeah
4:38:04dollar sign var watch what i'm going to
4:38:06do i'm going to pipe this to get member
4:38:09you would expect
4:38:10a result at this point look at what i'm
4:38:13getting
4:38:14i get no object has been specified in
4:38:16other words
4:38:17nothing went across the pipeline right
4:38:19host just
4:38:21destroyed everything that i've been
4:38:23working
4:38:24so hard for with objects right host has
4:38:27annihilated it by the way notice it
4:38:29showed dc on the on the coast
4:38:31yeah because it actually wrote it out to
4:38:34the house yes
4:38:35but there was nothing going down the
4:38:37pipeline and the point is we want stuff
4:38:38going on the pipeline
4:38:40so with right host we have a command
4:38:43that watch this
4:38:44write output dollar sign var
4:38:48and it does the exact same thing but
4:38:51it's doing it through the pipeline look
4:38:53get member look at what i got
4:38:56i got a real object that's crossing
4:38:57across there now
4:39:00so it matters but everybody says well
4:39:02you lost the ability to make colors
4:39:04get over the color thing we don't here's
4:39:07the deal we have ways for you to make
4:39:09colors
4:39:09properly you've noticed that powershell
4:39:11has a built-in color scheme
4:39:13that it uses and as you start to script
4:39:15this is going to become
4:39:16real paramount as admins we get used to
4:39:19certain colors
4:39:20popping up so in powershell we've
4:39:22included commandlets to use the existing
4:39:24color scheme if you just play along
4:39:26it'll all be good such as i want to
4:39:29write
4:39:30a warning please
4:39:34don't do that
4:39:37look it comes up as a powershell warning
4:39:40the yellow on black so it makes
4:39:41sense to my brain because i've seen
4:39:43those warnings before or things
4:39:45that i need to care about i didn't have
4:39:46to go through and use right host and
4:39:48come up with my own color scheme
4:39:50and of course we give you things like
4:39:51write error and there's other stuff that
4:39:54we have but right error being one
4:39:55stop touching me and
4:39:59now it looks like a power shell error
4:40:01message and i've generated the error and
4:40:03it's in the same color scheme in the
4:40:05same format so you don't need write host
4:40:07most of the time if you want to put
4:40:09something on the screen in a different
4:40:10color great but try to stick with right
4:40:12output and the other right
4:40:14commands that we give you to write
4:40:16things out to the screen especially when
4:40:18you're working with your
4:40:19your vars because right host couldn't
4:40:21can be
4:40:22somewhat problematic you know i'm
4:40:24checking this is very analogous to what
4:40:26i mentioned about the console
4:40:28remember i said i'm trying to kill off
4:40:30the console because i'm trying to kill
4:40:32off console apps
4:40:33because apps that write directly to the
4:40:35console can't be
4:40:36automated they are the enemy of
4:40:38automation right host is another flavor
4:40:40of a console app is another flavor of a
4:40:43console app so don't do it by the way
4:40:44there are times there are times we have
4:40:46a special
4:40:47like dispensation for people who are
4:40:50trying to to do this here's the key
4:40:52thing
4:40:52your say you want to write a script that
4:40:54was well formatted and had colors and
4:40:56all that good stuff that's fine
4:40:57but use the word show okay whenever you
4:41:00see the word
4:41:01show you should hear in your head ah
4:41:04i'm not going to be able to program or
4:41:06script the output of that
4:41:08so that's perfectly fine but just make
4:41:10sure you use the right term
4:41:11show right and then and yes most of the
4:41:15time just don't use right house
4:41:16okay okay just just don't do it it's
4:41:18because you like dogs
4:41:20it's because i like dogs and and i have
4:41:23to give don jones credit for that phrase
4:41:25who uses
4:41:26that all the time so let's do something
4:41:28kind of fun and kind of exciting at this
4:41:30point i
4:41:31i i think that's because you show them
4:41:32the squiggle brackets
4:41:34uh-huh the squiggle brackets you want to
4:41:36show them the variables with the
4:41:36squiggle brackets yeah
4:41:38really that's awesome here i'll do it
4:41:40it's okay here's me okay you're doing so
4:41:42here's the thing
4:41:43hey what can i do like hey this you know
4:41:45is this an anglo-centric english thing
4:41:47and the answer is no no no my friends
4:41:49like let's say you want to have you can
4:41:51put
4:41:51you can you have variables of any sort
4:41:53of names including spaces right
4:41:55so you can say hey this is a
4:41:58test equals four right
4:42:01and then this is a test
4:42:04it's four is that cool now check this
4:42:06out you can have anything you want in
4:42:08here right
4:42:09oh sorry get the wrong thing what the
4:42:11heck was that
4:42:12oh that wasn't good what did i do
4:42:16oh good lord help help help help me help
4:42:18me
4:42:20no i oh here we go
4:42:24there we go there that's what i meant to
4:42:27do
4:42:27okay there you go that's really weird
4:42:31wow whoa
4:42:34okay so now look that's the name of my
4:42:37variable oh did i screw that up i did
4:42:39screw that up
4:42:40oh no i did equals okay so that's the
4:42:43name of my variable is that crazy or
4:42:45what
4:42:45that's crazy but here it gets a little
4:42:47bit cooler
4:42:48because we draw this distinction between
4:42:50the syntax of a variable and the
4:42:51semantics of the variable
4:42:53so here the syntax is just showing you
4:42:55um
4:42:56it's a container and i i mentioned you
4:42:58could put any very
4:42:59any parameter you want you can use sorry
4:43:02any uh
4:43:03character you want you can using unicode
4:43:05etc it's not entirely true
4:43:07there's a special character and that is
4:43:10the colon character
4:43:11so let me make sure here's where i am
4:43:13imagine i do this imagine i do
4:43:151.5 okay and then i'm going to put that
4:43:18in a file
4:43:19test dot txt okay
4:43:22so now imagine watch this c colon
4:43:26jumpstart test.txt
4:43:32so look at that so i did dollar sign
4:43:35my parameters and i gave a file path
4:43:39and i get the value
4:43:42of the file so you're basically saying
4:43:45call and do this
4:43:46well it is hey this dollar sign syntax
4:43:50basically says where do i store my data
4:43:52and in general the way we think of
4:43:54variables is well you store data in
4:43:55memory somewhere and when the process
4:43:58goes away
4:43:59well that goes away right we'll look
4:44:01here look here look here
4:44:03wait a second so now i get a second
4:44:05command and i can say
4:44:07dollar sign c colon
4:44:12jump start slash test
4:44:17test.txt i did squiggle brackets
4:44:26slash slash
4:44:29i can get it there now wait so wait so
4:44:32equals
4:44:41i go to this machine and now
4:44:44so now i've got variables that cross
4:44:47cross
4:44:48that's awesome that is totally awesome
4:45:07[Music]
4:45:16so when we're doing remoting yes and
4:45:18remember in vote command we're now going
4:45:19to use the alias
4:45:20icm for this just to abbreviate things
4:45:24we're actually starting a remote
4:45:26powershell session
4:45:28yeah like you said we're feeding it a
4:45:31command
4:45:33then we're closing that powershell
4:45:35session and
4:45:36leaving right so we start a tcp
4:45:38connection tcp we start a process
4:45:41we load the clr we load powershell
4:45:44we initialize powershell we run all your
4:45:47profiles that can be up to four profiles
4:45:50we run those and when those are all
4:45:51ready then we take the code
4:45:54we execute it and we throw all that away
4:45:56and then we throw everything away so
4:45:58you this is important when you're using
4:46:00remoting we're going to connect to that
4:46:02box we're going to
4:46:03start all this stuff up we're going to
4:46:04climb up this mountain we're going to
4:46:06give it your
4:46:06little tiny code do that
4:46:09and then we have to tear all this down
4:46:12and walk away
4:46:13you can imagine that if you're going to
4:46:14do a lot of invoke commands in a row
4:46:17that's not very efficient so there's a
4:46:20way we can make this more efficient and
4:46:21i want to demonstrate it using variables
4:46:23first and then
4:46:24we'll take a look at some cool things
4:46:25that we can do with this so watch guys
4:46:27i'm going to go to
4:46:28i'm just going to do this on dc first
4:46:30and what i'm going to do is
4:46:31i'm going to show you what's happening
4:46:33i'm going to do dollar sign var equals
4:46:352.
4:46:36now think this through i'm going to go
4:46:38to the domain controller i'm going to
4:46:39start up powershell i'm going to
4:46:41set a variable and then i'm going to
4:46:44destroy powershell
4:46:45so what happens is is if i now ask it
4:46:49what's that variable on output
4:46:53on uh on dc well is anybody shocked that
4:46:58it's not there anymore when the console
4:47:00dies everything dies
4:47:02this is why powershell has to run all
4:47:03the time so nothing dies
4:47:05but no when the new console dies when
4:47:07that execute when powershell exe on the
4:47:10other side dies everything dies with it
4:47:12what i'd really like to do
4:47:15is i'd like to be able to connect to the
4:47:16machines go through starting all this up
4:47:19and leave it up yeah yeah i'm in you in
4:47:22for this yeah so we call those things
4:47:25sessions sessions you'd like to create a
4:47:27powershell session
4:47:28we're going to create a power so watch
4:47:30let's create the powershell session so
4:47:31what i'm going to do is i'm going to set
4:47:32this equal to a variable called
4:47:34sessions equals new
4:47:37ps session now i'm going to specify the
4:47:40computer and right now i'm just going to
4:47:41keep it real simple i'm just going to
4:47:42use
4:47:43the dc right now so what happens is that
4:47:46i've created a session
4:47:48that's going to keep powershell running
4:47:50on that remote machine now i'm only
4:47:52doing it to one machine right now but
4:47:54it's on that remote machine just to show
4:47:56you we have a command for get ps session
4:47:58that will show you what sessions you
4:47:59have notice
4:48:01got a session to that computer it's open
4:48:04life is good what i can do now is start
4:48:07using invoke command and instead of
4:48:08using dash computer name i can specify
4:48:10that i want to use
4:48:12this session so icm we're going to do
4:48:15the exact same example again so let me
4:48:17just go ahead and clear the screen here
4:48:18and i'm going to do icm
4:48:21computer oh no not a computer yeah
4:48:24dollar sign sessions of course i had to
4:48:25make it long and easy hard to type
4:48:27and i'm going to do the same thing var
4:48:29equals 2
4:48:31and this time i'm going to go back and
4:48:34check on it
4:48:38fast fast fast fast fast fast and this
4:48:40now gives us a lot of power to do a lot
4:48:42of
4:48:42really really cool things so we can keep
4:48:46this session open and we continuously
4:48:47fire things we can reference variables
4:48:49that we have open
4:48:50this is going to make our lives a lot
4:48:52easier um happy happy happy
4:48:54happy happy happy i can't show them the
4:48:55difference in time yeah yeah
4:48:57okay do you do measure commit you know
4:48:59measure command yeah do measure command
4:49:01on
4:49:02just invoke command minus command name
4:49:03or my computer name
4:49:05oh you want to see the difference in
4:49:07time oh yeah i wonder if that would
4:49:08you think it's going to be apparent here
4:49:09computer named dc yeah
4:49:11and do get process oh get process yeah
4:49:14that's good get process
4:49:15and then screw it and then uh no no no
4:49:18you put wrap that whole thing in a
4:49:19script block
4:49:20and put measure command at the beginning
4:49:26measure measure command
4:49:31so what's happening here is that the
4:49:33measure command is going to take what
4:49:34we're running
4:49:35and so you can see what it's doing is
4:49:37that it's it's showing us how long this
4:49:39is taking
4:49:40yeah i love text um but anyways
4:49:42milliseconds
4:49:43eight eight six milliseconds now do it
4:49:45with a session
4:49:47so let's do the same thing so i'm going
4:49:49to just do measure command let's just do
4:49:50up arrow man
4:49:51oh yeah me and my up arrows
4:49:54down one there now change computer name
4:49:58dc
4:49:58to okay let's do that it says 886
4:50:02886 to session dollar sign sessions
4:50:09five oh probably even faster but it's
4:50:12yeah it's going to actually be faster
4:50:14and here's the thing
4:50:15it is faster doing it this way um
4:50:18but now when it's really going to pay
4:50:20off being faster
4:50:22want to see something cool yeah yeah i'm
4:50:24going to draw okay
4:50:26watch wow this is when sessions and
4:50:29remoting
4:50:30change your world so i want to prove to
4:50:32you that i'm not lying to you
4:50:33so first of all i'm going to kill
4:50:35everything so you know that i'm not i'm
4:50:36going to kill the shell oink and i'm
4:50:38going to bring up a new one
4:50:39really that way you know that i've got
4:50:41clean shell i'm not hiding no no
4:50:43not rabbits nothing up sleeves anything
4:50:45like that here we go
4:50:47quick demonstration but see if you catch
4:50:49what's going to happen here first of all
4:50:50dollar signs servers
4:50:52equals who let's do s1
4:50:55and s2
4:50:58so you guys know in dollar sign servers
4:51:01well here
4:51:02you know cool
4:51:05watch i'm going to show you that i'm not
4:51:07cheating nothing's being hidden here
4:51:09start uh
4:51:11[Music]
4:51:12let me do it this way dollar sign
4:51:14servers
4:51:18coffee oh yeah um dollar sign servers
4:51:21and watch watch i'm gonna use a command
4:51:24called for each and what this is gonna
4:51:26let me do
4:51:27is iterate through each one of those
4:51:29coming across the pipeline so
4:51:30you know it's in dollar sign servers i
4:51:32got two computer names
4:51:34i want to grab the current one across
4:51:36the pipeline
4:51:37and use it in a special way so what i'm
4:51:38going to do is start http oops start i
4:51:42explore
4:51:45http dollar sign underscore think about
4:51:49this for a second guys here's what i'm
4:51:50going to do is
4:51:50start up i explore for each one of these
4:51:53and make it go to those servers to show
4:51:55you that there's no websites there
4:51:57there's no
4:51:58default web pages it's just going to
4:51:59come up and it's going to give me an
4:52:01error
4:52:01this can't be displayed all right so
4:52:04that's not that big of a deal but i just
4:52:06want you to see that i'm not hiding
4:52:07anything
4:52:08so now let's do a session and let's do
4:52:11something cool
4:52:12abandoned session let's just type dollar
4:52:15sign yes
4:52:16yeah you're right i type in way too much
4:52:18um equals new
4:52:20ps session and what we've done and what
4:52:22i want to do it to is
4:52:24dollar sign servers boom i'm going to
4:52:27get my sessions to these remote boxes
4:52:29now so just so that you see i'm not
4:52:31cheating multiple sessions
4:52:33multiple sessions you know what i want
4:52:35to do and this was an actual business
4:52:37problem that i've had several
4:52:38times um did i mention i was a web guy
4:52:39i'm just saying anyways um
4:52:41so here's the business problem i need to
4:52:43deploy
4:52:44uh actually i had a friend call me up on
4:52:46the phone um i need to deploy a web
4:52:4950 server website load balanced and i
4:52:53need to copy the website out from the
4:52:55developers and we have three months to
4:52:57do it
4:52:57can powershell help me with any of this
4:53:01seriously dude when's the last time you
4:53:04had a vacation
4:53:06well this conversation went on for a
4:53:07while me talking about vacations and him
4:53:09talking about this three month long
4:53:10project
4:53:13let's do it so with the session that we
4:53:16have
4:53:16three months what's that we only have
4:53:18like a couple hours
4:53:20throughout three months well let's okay
4:53:22okay
4:53:23okay so you want to challenge me okay
4:53:25fine okay fine so
4:53:26invoke command on the session that i
4:53:28just made which now is shorter dollar
4:53:30sign s
4:53:31here's what i want to do install windows
4:53:34feature
4:53:35web dash server now i know guys this
4:53:37isn't gonna be all that cool and tricky
4:53:39but
4:53:39um here's the thing uh for web services
4:53:42every component that you need of the web
4:53:44service
4:53:45you can just put in comma and specify
4:53:47every single one
4:53:48this doesn't have to be web servers this
4:53:49could be hyper-v servers this could be
4:53:51whatever it is you need deployed and i
4:53:54want you to see that it's happening
4:53:59that it pretend that the sessions for
4:54:02dollar sign s
4:54:03was 50 servers a thousand servers
4:54:07now take a look comes up and as it shows
4:54:09me as it's finishing the installation on
4:54:10those remote boxes
4:54:12and i'm maintaining this session so that
4:54:13i can still do it it's not
4:54:15serial it does it in parallel yeah it
4:54:17does it in parallel
4:54:18so what's happening is is that it's not
4:54:20going to this server
4:54:21and then going to this no it's going
4:54:23dudes install
4:54:27come on we're talking less than four
4:54:29minutes i've just deployed
4:54:31as many web servers as i want but wait
4:54:33we're not done
4:54:34watch there's more watch i'm just gonna
4:54:37up arrow
4:54:39for once and go back to this command
4:54:42watch oh oh come on
4:54:45oh i got oh come on yeah
4:54:48but wait there's one more step you guys
4:54:50we got to make our own web page right we
4:54:51got to make our own web page
4:54:57so three runs baby we're gonna make our
4:54:59own web page real quick just to prove
4:55:01that you can still do this uh yeah i
4:55:02just make this uh default htm and when
4:55:04students say
4:55:05mva and powershell
4:55:09rocks i'm going to save this i want to
4:55:12deploy this
4:55:14i want to deploy this so i'm going to
4:55:16dollar sign
4:55:17servers pipe for each
4:55:20one of those servers i'm going to have
4:55:23it
4:55:24copy item god i love i love i love the
4:55:28item commands to it to work with stuff
4:55:30because we're going to take that default
4:55:32htm and
4:55:34the coolest thing about powershell
4:55:36commandlets is they give you more
4:55:37capabilities you've ever had before
4:55:39because the destination
4:55:40can be a unc so i'm going to say
4:55:44backslash backslash dollar signup
4:55:46remember that's the current object
4:55:48that'll be
4:55:48those servers and i want it to go to
4:55:50their administrative share
4:55:52and i want it to go to inet pub
4:55:56this is where the default web page is is
4:55:58stored
4:55:59and
4:56:03and let's go up and run it again and lo
4:56:06and behold
4:56:08so aruba we're going it's vacation
4:56:12time now so in other words in just a
4:56:14couple of minutes i've deployed
4:56:15out in this case a web server and a
4:56:18website it's a small demonstration but
4:56:20the idea is this
4:56:22it changes how you think about
4:56:23administration now it's
4:56:25instead of sending guys out going uh go
4:56:27out there and install this and install
4:56:29that and
4:56:30let me know when you're done in three
4:56:32months now it's get somebody with a
4:56:34screwdriver to rack and drag these
4:56:35things
4:56:36as soon as they're powered up i'm going
4:56:37to remote into these things install what
4:56:38they need
4:56:39i'll probably script it so i never have
4:56:41to actually type these four commands
4:56:43again
4:56:43and boom it's done
4:56:46and now that i've got the script if i
4:56:48need to add more just add some more
4:56:50add some more or give it to me because i
4:56:53have a problem and you give it to me and
4:56:55i just do it give it to you like it
4:56:56might be more complex like i really
4:56:58don't understand this web stuff and i
4:56:59say
4:57:00oh i have this problem and you can say
4:57:02hey jeffrey here's a script i have i
4:57:04look and i said
4:57:05minus what if yeah do it off to a robot
4:57:09i mean that's the thing i think that is
4:57:11is some people just sort of don't get
4:57:13until they get it
4:57:14and that is the transformational effect
4:57:17of these technologies
4:57:18remoting in particular the fact that all
4:57:20of a sudden you're able to do
4:57:21just phenomenal things massive things
4:57:26in a heartbeat things that your boss is
4:57:28probably thinking
4:57:29i'm just not even going to ask because
4:57:30that's going to take so long
4:57:32we don't do things and so you end up
4:57:34with a sort of static
4:57:36brittle ossified excuse me ossified i.t
4:57:39data i.t processes and structures
4:57:42all of a sudden now with these tools you
4:57:44can become fast
4:57:46you can become flexible you can become
4:57:48agile you can do things you never
4:57:50thought of doing before
4:57:51all because of the power of powershell
4:57:54well it really is transformational it is
4:57:55transformational and also
4:57:57my cto doesn't like the answer it's
4:58:00going to take three months
4:58:02he really likes it when i give him the
4:58:04answer of
4:58:05it'll be done within the hour as a
4:58:07matter of fact it's done now i'm just
4:58:09testing
4:58:09yeah i mean that's the whole point to
4:58:12this is that your management totally
4:58:14changes
4:58:14not only in scale but what's that or
4:58:16like that guy i'll have a tea in the
4:58:18morning
4:58:18i'm going home yeah i'm going home
4:58:20that's the whole thing
4:58:21now one other thing i'm remoting that we
4:58:23want to show you right now we're
4:58:24promoting like
4:58:26uh
4:58:28[Music]
4:58:31there's one other super cool thing in
4:58:33remoting that we want to show you before
4:58:34we get into the rest of scripting
4:58:36and i have to do it with a new console
4:58:42you know i don't i'm not going to be at
4:58:45this machine
4:58:46tomorrow oh oh and i you know what in
4:58:50fact
4:58:50when i'm out on vacation and i'm using
4:58:53powershell web access who knows you know
4:58:55i'm going to be at
4:58:57some box and the thing is is that guys
4:58:59i've been using active directory
4:59:01commandlets i've been using all kinds of
4:59:02stuff from modules that are
4:59:04installed for the remote server
4:59:06administration tools and
4:59:08you know if i want to manage exchange i
4:59:10i need the remote server administration
4:59:11tools i
4:59:12am going to need to install the exchange
4:59:14management tools
4:59:16and i do a lot of scvmm stuff i'm going
4:59:18to need to install
4:59:20oh man all the vmm management tools
4:59:23god's going to take me a couple hours to
4:59:25do that
4:59:26and as soon as i go to a different
4:59:28machine
4:59:30and none of the commands none of the
4:59:32modules will be there none of it exists
4:59:34so i want to show you what i think is
4:59:36not is is absolutely the coolest thing
4:59:38in the world i use it constantly because
4:59:40on my box
4:59:42i don't install anything i don't install
4:59:43the remote server administration tools
4:59:44the exchange so it's nothing
4:59:46and here's the reason why put your seat
4:59:48belts on because this
4:59:49is freakish freakishly powerful
4:59:52this is this is this is the new world or
4:59:54order because here's the deal i don't
4:59:56have time to be installing tools
4:59:58every time i sit down in a box and the
4:59:59other thing is if i walk up to a server
5:00:01or something like that
5:00:03you're not going to be installing
5:00:04anything on there so i need a bunch of
5:00:06commandlets we're gonna
5:00:07i'm gonna need the active directory
5:00:08command i don't know why i'm starting to
5:00:10do it like this but it's kind of like
5:00:11watching
5:00:11godfather yeah it's like watching god i
5:00:13don't know what i'm doing um
5:00:15you call me funny yeah it's funny i'm
5:00:18funny funny
5:00:19you say you got powershell you just
5:00:20stick down you know so here we go
5:00:24so what i'm going to do is i'm going to
5:00:25create a session to the
5:00:27servers that have the commandlets that i
5:00:29want now think about this
5:00:32you really want the commandments from
5:00:34the servers that
5:00:36naturally have them a domain controller
5:00:38has the active directory commandments
5:00:39an exchange 2007 server has the
5:00:43exchange 2007 command let's an exchange
5:00:462010 server has the exchange 2010 ones
5:00:49i couldn't get all those tools on my box
5:00:51if i wanted to
5:00:52but watch and you don't want to and you
5:00:55don't want to so dollar sign s
5:00:56equals new ps session and in this case
5:00:59i'm going to uh
5:01:00i'm just going to hit a domain
5:01:01controller
5:01:03so i'm gonna establish a session to this
5:01:05domain controller
5:01:07import um ps session
5:01:12module guys do you see what i'm doing
5:01:15there's a module on that remote server
5:01:17called active directory so i'm going to
5:01:19say
5:01:19give me that module active directory
5:01:22now because i right now on this vm
5:01:26i do have the rsat tools i'm going to
5:01:27prefix this so there's a prefix and i'm
5:01:29going to call it remote so you know it's
5:01:31coming from somewhere else
5:01:32then we're going to ask jeffrey how to
5:01:34explain how this magical stuff works
5:01:36because watch as soon as i do this
5:01:39to oops i forgot to give it the session
5:01:42darn dollar sign s i was going to do it
5:01:44all in one line and i screwed it up i
5:01:45forgot the session
5:01:47oh yeah no you can't that's a string oh
5:01:49it's
5:01:50yeah so let me do this you see dollar
5:01:52sign session there we go
5:01:53way back machine you didn't see that
5:01:55click click click ben and black
5:01:56men in black men in black so module
5:02:01session dollar sign ass
5:02:06i don't know if you know what just
5:02:07happened right now but check this out
5:02:09i wonder if i have any command let's now
5:02:11pretend that i had no active directory
5:02:13command so what we're going to do is i
5:02:14wonder if i have anything for remote
5:02:16remote remote remote room ah let's do
5:02:18this remote um
5:02:20a.d should work
5:02:24dudes do dude that's ducey's you see
5:02:26what's scrolling across my screen right
5:02:27now
5:02:28looks and smells like i suddenly have
5:02:30all these commandlets i just asked for
5:02:31look at all these active directory
5:02:32commits yes they're prefixed with remote
5:02:34so
5:02:35i have these command matter of fact i
5:02:36can do this watch get
5:02:38remote a d computer
5:02:42filter fiddler
5:02:45yeah this is brother anyways the star
5:02:49so look it ran look at this look look
5:02:52look
5:02:53i got these commands from a server it's
5:02:55nothing's installed how is this working
5:02:56explain to me how this is working
5:02:58because this is like freaking me out
5:02:59right now it's magic baby i love
5:03:01magic so here's the deal um here let me
5:03:04show you this
5:03:05so here we've been showing people get
5:03:08command
5:03:09or sorry get help get help but get help
5:03:12get help
5:03:12get process okay
5:03:16and that gives you this but there's
5:03:18another thing that's called get
5:03:20command and people have often asked well
5:03:22what's the difference between these two
5:03:23get help versus get command and the
5:03:25answer is that get command
5:03:27is more structural programmatic
5:03:30information so watch this dollar sign
5:03:32c dollar signs hello oh wrong one
5:03:36i'll assign c equals get command dollar
5:03:38sign c dot
5:03:39parameters okay and then let's take a
5:03:42look at this parameter
5:03:43say name oops sorry name
5:03:48okay and look we've got all the
5:03:49information the name its type etc yeah
5:03:52okay
5:03:53and so what happens is when i go and
5:03:56i do that import what i do is i go to
5:03:59that remote machine
5:04:00i load the module that you asked for and
5:04:03i do a get command on all the things
5:04:06and i get that data structure and what i
5:04:08do is on this side on now on
5:04:10on my side i go and i take that
5:04:13information
5:04:14and i recreate a set of scripts with
5:04:16exactly the same signature
5:04:19and then the body of the function
5:04:21basically says hey when you go do this
5:04:23gather all that stuff up and run it over
5:04:26there
5:04:26using invoke command i don't actually
5:04:29have these commandlets
5:04:30on my machine i have a a a like a
5:04:33proxy yeah or or a shortcut
5:04:37that is saying take all the information
5:04:39from the parameters and then go run it
5:04:40on the desk
5:04:41the source machine exactly so do this do
5:04:43on your machine now
5:04:44type get command get command get dash
5:04:48star 80 computer get dash
5:04:51star 80 computer
5:04:56okay so look notice one the get 80
5:04:59computers commandlet now that
5:05:00that command net code okay okay but look
5:05:04at the function
5:05:06so now take a look and do this uh type
5:05:10parentheses paren get command
5:05:14get remote 80 computer
5:05:17get remote ad computer and
5:05:21print dot definition
5:05:24ah definition will it ah
5:05:28yeah so look at this this was
5:05:30dynamically generated
5:05:31code dynamically generated code on my
5:05:35side
5:05:35on your side that says grab these
5:05:37parameters oh so you know what let me
5:05:39just say
5:05:39in in powershell version two was a
5:05:42pivotal technology
5:05:43in powershell version one uh uh
5:05:45commandlets
5:05:47had to be.net in powershell version two
5:05:50we said commandlets could be dotnet
5:05:53or powershell itself okay so now
5:05:57powershell scripts are full commandlets
5:06:00which you're going to see in a little
5:06:01bit guys now this was a
5:06:03transformational technology because what
5:06:04it means is now the sudden
5:06:06you can write programs which generate
5:06:09commandlets
5:06:10dynamically and that's what we do here
5:06:12that's what that import ps session does
5:06:15we go and we get a data structure we
5:06:17have a program that
5:06:18dynamically generates a powershell
5:06:21script
5:06:22that has exactly the same signature as
5:06:25the
5:06:25net commandlet on the remote machine has
5:06:28exactly the same signature
5:06:30i gather up all that information and i
5:06:32then
5:06:33run it on the remote machine and i think
5:06:35what the is so to make sure the concept
5:06:37is good
5:06:38is that we're just like jeffrey said
5:06:40this is
5:06:41it looks and tastes and feels like the
5:06:43commandlets are here on my machine but
5:06:45they're not they're functions that are
5:06:47going back and running it on the remote
5:06:49machine
5:06:49so think about this who's going to be
5:06:51better at running get ad computer
5:06:53anyways your box or the domain
5:06:56controller
5:06:57so first of all that's going to be
5:06:59faster but you know you were telling me
5:07:00about this scenario and
5:07:02i i love this scenario about the guy who
5:07:04had to do a migration from exchange
5:07:06yeah of of um i had to
5:07:09do a migration from exchange 2007 to
5:07:12exchange 2010.
5:07:13you're not going to get those tools all
5:07:16installed on your box
5:07:17but you can import both sets of
5:07:20commandlets
5:07:21prefix one with 2007 prefix another with
5:07:242010
5:07:25now you got both sets of commandlets all
5:07:27in the same place
5:07:28and you can get the two products to work
5:07:30together exactly it was doing the
5:07:31equivalent of like
5:07:32get uh like i'll just say v1 v2 get v1
5:07:36uh user pipe to set v2 user
5:07:40right and what's happening is he's on
5:07:41this box he's getting the
5:07:43users from this machine and he's setting
5:07:45them on that machine and this is the
5:07:46power of this stuff now
5:07:48all of a sudden i mean it used to be
5:07:49that integration was just
5:07:51painful right i got to find all this
5:07:53stuff i got to get it all in this box so
5:07:55it bloats the box i'm
5:07:57running out of disk space oh wait this
5:07:59guy updated something i got gotta patch
5:08:01it
5:08:02oh wait they require different versions
5:08:04of stuff
5:08:05just hideous idiots videos and now the
5:08:08answer is
5:08:09hey dude i'm sitting right here i import
5:08:11the stuff from there i import the stuff
5:08:13i
5:08:13import the stuff i import the stuff and
5:08:15i'm sitting here and by the way type
5:08:17type type type type look you got tab
5:08:19completion okay
5:08:21so get remote and look
5:08:24well here let me do remote so that we uh
5:08:28look yeah also you got tab completion
5:08:31you have help
5:08:32everything you got everything and help
5:08:34will discover
5:08:35all of this so you've got full
5:08:36discoverability you got full help
5:08:38it looks and feels like it's here but
5:08:40it's running in the best place
5:08:41possible which is on those machines and
5:08:44i didn't have to install
5:08:45anything now this is referred to as
5:08:47implicit remoting and you're probably
5:08:50going to want to do this yourself it's
5:08:51already in the slides but we'll also
5:08:53give you some more references
5:08:55for the implicit remoting and to be
5:08:56honest when i'm managing i literally
5:08:58this is what i'm doing i don't install
5:09:00anything on my local box because i'm not
5:09:02too sure as a consultant what box i'm
5:09:04going to be
5:09:05on so i'll just implicitly remote the
5:09:07commands that i need when i need them
5:09:09um you know what we here's the other
5:09:12thing that's so important
5:09:13is when i imagine i'm going to go get
5:09:15this stuff from different things
5:09:17uh over here i might need a different
5:09:19set of credentials than over there
5:09:20right so instead of having to type the
5:09:23credentials all the time
5:09:24you create the session with a set of
5:09:26credentials you import the commandlets
5:09:27those credentials are then used every
5:09:29time and
5:09:30guys there's a dash credential parameter
5:09:33on this so when you create the session
5:09:34yeah you use the credentials that you
5:09:36want to use when you do
5:09:38the import of the of of the modules
5:09:41then it's you're using those credentials
5:09:43over and over and over again so you
5:09:44don't have to keep track of all of that
5:09:46it's it's
5:09:47it really makes your life a lot easier
5:09:49and cuts down on all the minutia of
5:09:51tools and all this kind of stuff yeah i
5:09:53really encourage you guys to go
5:09:55try this even if you do it locally like
5:09:56here let me show you something i'll just
5:09:58show you how to do it locally right
5:09:59because it's just so freaky
5:10:00so here uh you can do
5:10:03uh i just say dollar sign s equals new
5:10:05session and that'll connect to locally
5:10:07right your local machine and then you
5:10:09can do import
5:10:11ps session dollar sign s
5:10:14minus and we'll just like do one command
5:10:17like nice command
5:10:18get process minus prefix
5:10:22prefix wow right and so all of a sudden
5:10:25you get get
5:10:27wow process
5:10:31and and it just works okay
5:10:34so the point is you know just try it
5:10:36right because you don't necessarily have
5:10:38to have access to some remote machine
5:10:39with the main controllers and all that
5:10:41stuff you can do it on your local box
5:10:43uh but it is so freakishly cool i mean
5:10:45you just want to have fun with it
5:10:47it's seriously going to solve a lot of
5:10:49business problems for you going forward
5:10:51i mean just grabbing the commands from
5:10:53the machines that have them you've got
5:10:54the correct versions
5:10:56you know of whatever product you're
5:10:57working with implicit remoting is truly
5:10:59a godsend
5:11:00for this now guys we're going to take
5:11:02another 10 minute break and we're going
5:11:03to have our last session
5:11:05for today for today today and it's going
5:11:08to be
5:11:09on we're going to start scripting we're
5:11:11going to start
5:11:12seeing what the script looks like so
5:11:14come back and join us in 10 minutes and
5:11:15let's automate
5:11:16and then in two weeks we do the advanced
5:11:18one now the advanced one
5:11:20we roll up our well they already rolled
5:11:22up we roll up our sleeves and we get
5:11:24into the scripting the automation et
5:11:26cetera
5:11:27yeah the hardcore stuff but this is a
5:11:28taste that i think you're going to enjoy
5:11:30and it'll get you working
5:11:31and it'll get you prepped for what you
5:11:32need in two weeks so see you in 10
5:11:38[Music]
5:11:44minutes
5:11:52[Music]
5:12:00and and we're back for our last session
5:12:03for today
5:12:04last and best last and best session for
5:12:06today guys before we forget we should
5:12:08just give a super shout out to the mvps
5:12:10uh
5:12:10answering all those great questions yeah
5:12:13thank you
5:12:14again uh just representative example of
5:12:16the awesome powershell community
5:12:18join be part of the powershell community
5:12:20let's go
5:12:21and so guys what we're going to do is
5:12:23this is kind of a warm-up for what we're
5:12:24going to do on august 1st where we go
5:12:25through all the details in this this is
5:12:28more than just a warm-up though you can
5:12:30start immediately using this today i
5:12:31like to refer to this as immediately
5:12:33effective and so
5:12:34let's start off with though
5:12:38thank god you're not physically in this
5:12:41room because
5:12:43what i'm about to show you i've actually
5:12:45had people threaten to hit me
5:12:48oh so you have to imagine that no don't
5:12:51hit me man don't
5:12:52you just got punched by jeffrey snowden
5:12:54that's going to look really good on my
5:12:55resume
5:12:56um so we've been spending all of our
5:12:59time
5:12:59in the console and god i love the
5:13:02console and we've been working on
5:13:03commands and here's what you want to do
5:13:04you want to work stuff out in here
5:13:06copy it and like we did earlier paste it
5:13:08into a script but i want to show you
5:13:10something that comes with
5:13:12powershell and it's the ise and
5:13:15yeah i know and this is where so i'm
5:13:17going to close this console and guys i
5:13:18want to show you this real quick so that
5:13:20we can kind of get into it but
5:13:22i'm going to start the ise and you know
5:13:25they're going to do that
5:13:25picture-in-picture thing so let me lower
5:13:27this thing down here a little bit
5:13:30now i'm going to show you don't yell at
5:13:32me please don't yell at me first of all
5:13:34there's a scripting pane up here down
5:13:36here is a console pane then there's this
5:13:38commands pane i'm going to
5:13:40simplify this screen real quick
5:13:44and i want to show you these buttons
5:13:45across the top you can have
5:13:47the the scripting pane on top and a
5:13:49console on the bottom you can have them
5:13:51side by side which if you have two
5:13:52monitors
5:13:53this is awesome yeah to put this between
5:13:55the dual monitors
5:13:56but i'm going to make it even simpler
5:13:58i'm just going to go to one pane and so
5:14:00i can kind of shorten things up a little
5:14:01bit here
5:14:03and and bring this down a little bit
5:14:05here's the part that you're going to
5:14:07threaten to beat me to death with i'm
5:14:09going to hit control r that flips me
5:14:11between
5:14:11the scripting pane and the console and
5:14:14you might be asking yourself
5:14:15well this looks kind of like a console
5:14:18yeah this is a damn fine console
5:14:20remember this morning
5:14:22when we were talking and jeffrey was
5:14:23saying hey look we can't touch
5:14:25that original console thing that you
5:14:27know controller
5:14:29huh i didn't know that what controller
5:14:32yeah it's awesome
5:14:33oh i keep trying to remember control d
5:14:35versus control i
5:14:36like d what the hell is no i think i
5:14:38think bruce pan i think bruce payette
5:14:40did something with control r and i'm
5:14:41like
5:14:42so yeah controller oh i've learned
5:14:44something oh that's
5:14:45uh yeah right on bro so here's the deal
5:14:49i'm going to type something here and
5:14:51you're going to see that this is not the
5:14:53console that
5:14:54you think we are first of all let me
5:14:56clear it up now watch
5:14:58i'm going to do get
5:15:01look at what it's doing look at what
5:15:02it's doing
5:15:04dude this is like it's it's intellisense
5:15:08helping me through here this is like
5:15:10totally awesome and watch
5:15:12you might notice that it's also
5:15:16color syntax so
5:15:20here's the deal and we're going to ask
5:15:21jeffrey about this because
5:15:23this is the coolest thing in the world
5:15:25you've got a console that has color
5:15:26syntax coding which
5:15:27helps a lot when you're typing to see if
5:15:30you're typing an error
5:15:31and it's got this help flying at me as
5:15:34i'm typing
5:15:37is this your solution to the the the
5:15:39console going forward is it because
5:15:40this makes it makes it a lot easier yeah
5:15:42right take spend a couple of
5:15:44hours with this and stop asking me about
5:15:46improving the console
5:15:47that's that which is what the thing was
5:15:49this morning is don't ask about
5:15:50improving the console because they're
5:15:52doing it right now and this is the way
5:15:54to do it so
5:15:55let's use this console and let's let's
5:15:57let's take a command here let's do a git
5:15:59wmi object yeah
5:16:00it's okay it's okay we'll all be good
5:16:02win32 underscore logical disk
5:16:04i just want to show you i want to get
5:16:05something to work and i'm going to type
5:16:06something in you probably haven't seen
5:16:07before
5:16:08you will but i'm going to do device
5:16:12filter on device id equals
5:16:16c i want you to see what it gives me as
5:16:19an output well
5:16:20absolutely nothing because i screwed up
5:16:22the filter
5:16:24and so what this command now gives me is
5:16:27it gives me some useful information it's
5:16:28giving me um i'm having a scroll issue
5:16:30here hang on
5:16:32it's giving my drive c and it gives me
5:16:33free space and size i don't like the
5:16:35numbers
5:16:36so i'm going to do something in flight i
5:16:38want you to notice i'm building a
5:16:40command to make sure that it works first
5:16:42and then i'm going to show you how easy
5:16:43cool this gets so
5:16:46what i'd like is i'd like to select and
5:16:49i'm only going to take one property for
5:16:50this demonstration so i'd like to use
5:16:52the free space
5:16:53but you know what i can't stand is okay
5:16:57let's just do free space watch
5:17:00i i don't know about you but i don't
5:17:02really like that number because that
5:17:03number is like in bytes and
5:17:05it's like not making me happy because i
5:17:08want to see it like gigabytes or
5:17:09something like that
5:17:10because can't point sit down yeah
5:17:13so you did get wmi object do get sim
5:17:16object
5:17:18and then yeah wait yeah no let's start
5:17:20from scratch
5:17:21okay let's start from scratch you want
5:17:24you want get
5:17:24sim object get sim object get sim object
5:17:28or sim instance instant sorry yeah and
5:17:30say win32
5:17:32lodge and then tap tap tap
5:17:43and then control space control space
5:17:47and then control space
5:17:54that's awesome intellisense against the
5:17:56wmi namespaces
5:17:58oh and guys when you start working with
5:18:00wmi one of the hardest things is dealing
5:18:02with the namespaces and finding the
5:18:03classes and this is one of the most
5:18:05important technologies out there we
5:18:06haven't had time today to go through it
5:18:07but
5:18:08this is awesome oh yeah
5:18:12yeah so and you're going to be wanting
5:18:13to use get some instance instead of the
5:18:15old-fashioned command that i'm going to
5:18:16use right now
5:18:18okay and so i'm going to do select free
5:18:21space i can't stand that number so
5:18:23i'm going to do a custom column i'm
5:18:25going to just like we had done earlier
5:18:27because i don't like that i'm going to
5:18:28create my own there's a reason i'm doing
5:18:30this but don't panic we're almost there
5:18:32and so i'm going to call it free gb
5:18:36and uh oops would help if i put in
5:18:38something to tell it what i was doing
5:18:40and you're not showing the best
5:18:44practices
5:18:47hit the cancel up to the pipeline and
5:18:50now it hit carriage turn oh well but
5:18:54but but oh it doesn't do that in the ise
5:18:57it doesn't only in the console
5:18:59i i know what you so here's what jeffrey
5:19:01is saying and i'll show it to you in
5:19:02there
5:19:02and in here so because i want you to see
5:19:04this because you guys this will actually
5:19:06be really interesting
5:19:08i want you to see that watch so i'm
5:19:10doing this this long line here get wmi
5:19:13object win32 underscore logical disk
5:19:17logical desk
5:19:19filter and device id
5:19:24equals c colon and guys here's the thing
5:19:28is that i want to that's great and
5:19:29that's fine that's dandy
5:19:31but i'm going to start typing this long
5:19:33command that's going to be wrapping
5:19:34around
5:19:35a really great great way to work at the
5:19:37console is to realize that
5:19:39there are certain things that
5:19:40automatically give us line continuation
5:19:42the pipeline being one of them watch
5:19:44what happens here when i strike in or
5:19:46after the pipeline see these things
5:19:51this means i'm not sure but it means
5:19:55you're you're we i we get it you're
5:19:57still on the same line
5:19:58just keep typing so from here i can do
5:20:00my select
5:20:02it becomes easier to read and it's
5:20:04easier to edit when you're doing stuff
5:20:06in real time
5:20:07um select and i'll do my
5:20:10at n equals uh
5:20:13free gb and
5:20:17oops uh it's late in the day x e
5:20:20equals and i'm going to take the current
5:20:23object across the pipeline i'm going to
5:20:24grab its free space
5:20:26and i want to see it in gigabyte so i'm
5:20:27going to divide it by
5:20:301gb we have these built-in things to
5:20:32help us with math because i'm not good
5:20:33at math so
5:20:34these help me with math and so the
5:20:36number looks a strike enter on this line
5:20:38number looks better
5:20:39but i'd like it all rounded up so i'm
5:20:41just going to do this as an integer real
5:20:43quick
5:20:44now i'm going to do it as an integer
5:20:48real quick
5:20:48but it's going to yell at me because i
5:20:49didn't run both lines
5:20:52so let me do this no that's fine that's
5:20:54fine and so as int
5:20:57and oops now i screwed something up
5:20:59right hang on brackets i forgot the
5:21:01brackets
5:21:03i'll get you a good line of code don't
5:21:05panic this is all in the slides too so
5:21:07if i can't fail to type
5:21:09boom so i've got a nice line now
5:21:12i've got something that's giving me
5:21:13information that i want it's pretty cool
5:21:15got it all worked out what i'm going to
5:21:17do is
5:21:18cut and paste now from here you know cut
5:21:19and paste is kind of hard to do but if
5:21:21you did this over here
5:21:23cut and paste is really easy to do
5:21:24because you know what's funny is they
5:21:26figured out how to use things like oh
5:21:28let's see and this old this old
5:21:30technology called
5:21:31control c control v so i'm going to say
5:21:34control c
5:21:35i'm going to hit control r to flip the
5:21:36screen so i'm going to control v
5:21:39oh yeah baby now i've got my line
5:21:42now we're going to start having some fun
5:21:43because we're going to save this as a
5:21:44script right now
5:21:45file save as we'll uh
5:21:49save it uh here in my scripts folder
5:21:52we're gonna save it as uh well we did i
5:21:53love you uh
5:21:54let's do this as let's just call it disk
5:21:56info dot ps1
5:21:59and i can run it from right here if i
5:22:01run it boom shows me a result
5:22:02uh it helps if i clear the screen and
5:22:05everything else i typed but
5:22:07i can run it oink and it shows me the
5:22:09results i'm going to hit control r
5:22:11everything's good now we want to start
5:22:14adding stuff to this
5:22:16so let's make this a little better first
5:22:17of all you know this is a nice script
5:22:19and all this but if i give it to
5:22:20somebody else all it's doing right now
5:22:21is getting
5:22:22information off the c drive on the local
5:22:24machine that's not
5:22:25cool i wanted to be able to get it from
5:22:32whatever computer i want it to get it
5:22:34from now i can sit here and hard code
5:22:35this
5:22:37dude computer name right i'm not
5:22:40spelling anything right
5:22:41computer
5:22:46name localhost and this will work but
5:22:50yeah go ahead and save it that's fine
5:22:53but
5:22:54here's the problem if i give this to a
5:22:57friend
5:22:59what are they going to have to do
5:23:00they're going to have to go in here and
5:23:02edit my script and i don't want people
5:23:05editing my script
5:23:06what could possibly go wrong especially
5:23:08if you digitally signed it
5:23:10especially if i digitally signed it so
5:23:12what i'm going to do is let's do a
5:23:13simple concept
5:23:14let's make a variable up here called
5:23:16dollar sign computer name
5:23:18and let's set it right now equal to
5:23:20localhost just to have
5:23:21some value in there and instead of
5:23:24we'll put the variable in here now this
5:23:26is kind of common to a lot of other
5:23:28scripting languages where
5:23:29what you would do is you put your
5:23:32variables up here so you'd make it
5:23:33easier
5:23:35for somebody to edit your script i still
5:23:38don't like this
5:23:39whole editing my script thing but i want
5:23:41you to see that this still works right
5:23:43all i'm doing is
5:23:44is putting it into dollar sign computer
5:23:46name still prints it out
5:23:47everything's cool you know
5:23:51let me show you how to test the script
5:23:53properly from the console
5:23:55because i'm about to blow your mind
5:23:57something that these guys have done
5:23:58is awesome so let's run the script from
5:24:01the console since a lot of scripts get
5:24:03run from the console i actually like to
5:24:04test them from there
5:24:06yep cds
5:24:10and so we called this disk info
5:24:13run it we're good happy happy happy
5:24:16happy but you know what
5:24:18i've been learning powershell and as an
5:24:21administrator
5:24:23this isn't exactly what i expect i
5:24:25expect i don't want to
5:24:26go in and edit computer name no when we
5:24:29have commandlets and stuff
5:24:31we get parameters that we can adjust so
5:24:34you know would be really cool
5:24:36i think i think it'd be really cool if
5:24:39there's this special keyword called
5:24:42param
5:24:44open parentheses close parentheses
5:24:50indent so that jeffrey loves you that's
5:24:52right
5:24:53make it look pretty i want you guys to
5:24:55notice something i'm going to save this
5:24:57so i'm going to hit ctrl s
5:24:58and save it i'm going to go back to my
5:25:00powershell console
5:25:04and watch this i'm going to clear the
5:25:05screen dot disk info
5:25:08dash oh
5:25:15i just made a parameter oh it was so
5:25:18easy
5:25:19to make a parameter so now i can type in
5:25:21any computer i want
5:25:23now i'm not selecting out a computer
5:25:25name which we will fix but i want you to
5:25:27kind of get the concept of
5:25:30i just put a variable in here matter of
5:25:31fact let's do another one let's just
5:25:32call it bogus
5:25:34just so you can see i'm going to go back
5:25:36here watch watch my chest it's so cool
5:25:40um let's do
5:25:45i'm making parameters on the fly for
5:25:47whatever i need
5:25:49this is becoming what's called a
5:25:50parameterized
5:25:52script and what you're getting is it's
5:25:54starting to
5:25:55kind of smell look and feel more like a
5:25:58commandlet
5:25:59it's making my life a little bit easier
5:26:02i'm liking this so let's try this i i
5:26:06there's another thing that would be
5:26:07really nice is if if
5:26:09for for an instance at least get help
5:26:12dot
5:26:12disk uh info yeah
5:26:16look at what powershell is doing
5:26:17powershell is starting to build that
5:26:19syntax for me but i a computer name it
5:26:22says it's an
5:26:23object no uh let me go in here and you
5:26:25can strongly type what the variables
5:26:28are we didn't haven't talked much about
5:26:29that but i want this to be a
5:26:31string so when i go out here and do this
5:26:34again
5:26:37notice it's now making it a string and i
5:26:39want you to notice that between the
5:26:41chihuahuas it says string it doesn't say
5:26:43that it can take multiple objects we
5:26:44don't have any of the binkies in there
5:26:46so here's how we put binkies in there
5:26:50[Music]
5:26:54and
5:26:56i'm starting to actually get syntax now
5:26:58built on these parameters
5:27:00and the only thing i've had to do so far
5:27:02is add one keyword different from what
5:27:04i'm used to and this one called param
5:27:06but wait there's more oh wait it gets
5:27:08better
5:27:10we're going to turn something on so that
5:27:12you can use
5:27:14parameter attributes yeah so let's do
5:27:17commandlet binding
5:27:20this turns on something called parameter
5:27:22attributes and here's the thing i don't
5:27:23really want to have local host in here
5:27:25what i want to do oh whatever
5:27:27just hit save just hit save yeah yeah
5:27:29and now do get help
5:27:30okay oh i see what he okay now what what
5:27:33he added one line of code one line
5:27:35one line of code and watch what happens
5:27:39what well that wasn't that wasn't it did
5:27:41i save it i think i saved it
5:27:43oh well we got common parameters so yeah
5:27:45it did okay we just need to do the
5:27:47um yeah so we got common parameters so
5:27:49this is actually making the syntax full
5:27:51watch watch so command binding will let
5:27:54us
5:27:54use something called parameter
5:27:56attributes things like making things
5:27:58mandatory
5:27:59let me show you an example i'm going to
5:28:00get rid of this default
5:28:03and i'm going to go in here and i'm
5:28:06going to say
5:28:08uh parameter i got to spell this right
5:28:13mandatory mandatory
5:28:16equals true and i think i got the syntax
5:28:20correct now i want to point out that
5:28:22this is a parameter attribute i'm going
5:28:23to say mandatory is true it only affects
5:28:26the next parameter after it's not going
5:28:27to affect bogus
5:28:29so watch look at what happens to the
5:28:31syntax on this
5:28:33notice up here
5:28:36i had the brackets around it now look
5:28:38there's no brackets around that this is
5:28:40going to become mandatory so watch as i
5:28:42start to try to run this
5:28:44i'm going to do disk info i'm going to
5:28:47run it
5:28:48oh you got to give me a computer name
5:28:49man so it's mandatory now
5:28:52dc and now it works i can do it
5:28:56i've made it mandatory i can also then
5:28:58do
5:28:59of course i've got the actual parameter
5:29:01so in just
5:29:02two lines of code we're making our own
5:29:05parameters
5:29:06on our script a parameterized script and
5:29:08we're getting syntax but you know what i
5:29:10want to be a nice guy when i give this
5:29:11to somebody else
5:29:12i want to be a really nice guy when i
5:29:14give it to you i want to be a great guy
5:29:16so what do you say we add in a little
5:29:18bit of help i love it
5:29:19love it let's do some help guys this is
5:29:22a uh
5:29:24a a block comment now usually when you
5:29:27type in comments see how they're in
5:29:28green
5:29:29usually the the parsing engine that will
5:29:31just ignore what's ever in there but
5:29:33with power shell watch i'm just going to
5:29:35type in a couple of things synopsis
5:29:38i'm going to say this is the short
5:29:41explanation
5:29:42it's okay if i have typing mistakes at
5:29:43this point because tired
5:29:46description this is the long
5:29:49disc yeah everybody's gonna be making
5:29:51fun of me because i can't type in i'm
5:29:53gonna type in
5:29:54parameter whoops what's what
5:29:57parameter and i'm going to say computer
5:29:59name
5:30:01and i'm going to say this is for remote
5:30:03computers
5:30:04and just just a couple more things here
5:30:06real quick uh example
5:30:08um let's do an example of uh oh let's do
5:30:11uh
5:30:12disk info uh dash computer name
5:30:16you know remote and let's do one more
5:30:19this is for this can we do an example
5:30:23this oh
5:30:28remote computer watch
5:30:31look guys just a couple of things this
5:30:34is going to be totally amazing
5:30:37let's do this all over watch much get
5:30:39help
5:30:44lookie does it look like powershell help
5:30:47now
5:30:49so i've got i've got name synopsis look
5:30:52it's building the syntax i got
5:30:53description but wait that's the
5:30:55short help watch watch one watch full
5:30:59oh now look what powershell's built for
5:31:02me it shows me the parameters the
5:31:03parameter definitions
5:31:05it's going to i've got an example down
5:31:07here for crying out loud
5:31:08this is what i want i want to give this
5:31:10to somebody else that works with
5:31:11powershell because this is what they
5:31:13expect
5:31:14oh this is making me so happy now can i
5:31:17just point something out yes
5:31:18absolutely i can never remember any of
5:31:20this i can't remember any of this either
5:31:22well you did well that's pretty good i
5:31:24can't do that
5:31:25so show them the amazing control j so
5:31:28guys
5:31:30i'm going to hit the only way i can deal
5:31:32with it and and here's the thing
5:31:33and when we come back on august 1st this
5:31:35is going to become one of your best
5:31:36friends so
5:31:37i'm going to start a new tab just i'm
5:31:39going to hit ctrl j it's going to bring
5:31:41up snippets now i want to point
5:31:42something out
5:31:43i'm not quite done with this
5:31:44demonstration yet but these snippets
5:31:46look at this
5:31:47commandlet snippet it gives you
5:31:50the basics of putting this together and
5:31:53the advanced one the complete one
5:31:54is super rock and cool but we've got
5:31:57comment blocks and we've got
5:31:59some of the the constructs and then the
5:32:01loops that we're going to be using on
5:32:02august 1st that you'll be able to
5:32:04work with to help you build this um
5:32:08so you could actually pick a a snippet
5:32:11and look it auto creates all these
5:32:14possibilities for you and oh look
5:32:16it see all you got to do now is just go
5:32:18in and so if you
5:32:19are a deeply flawed human like me and
5:32:21cannot smell synopsis
5:32:25this is what my problem is so you can
5:32:28use this as a
5:32:29template and to fill it up but wait
5:32:32there's more we're not done yet because
5:32:33here's the deal um this is nice this is
5:32:36a parameterized script and you can do
5:32:38a lot of powerful things with
5:32:40parameterized scripts but you know
5:32:43i want to take this to the next level
5:32:44just a little bit more so you can get an
5:32:46idea of where we're going to go on
5:32:47august 1st take it to 11.
5:32:49take a tool my amp goes to 11. it does
5:32:53um so we're going to go we're going to
5:32:54crank this bad boy up because
5:32:56my ise goes to 11. save script no let's
5:32:59do this
5:33:01so that you can see the typing what i'm
5:33:03going to do is i'm going to remove the
5:33:05help for it right now
5:33:07okay so don't don't freak out on me i'm
5:33:08just going to are you doing that well
5:33:10because i want them to oh i guess i can
5:33:11just scroll yeah
5:33:12no click click the button oh click the
5:33:14button on you just
5:33:16collapse yeah oh because highest c goes
5:33:19to the left oh yeah because ise goes to
5:33:2111 so
5:33:22here we go guys right now we're running
5:33:25this like a script i don't know about
5:33:26you but we ain't done this all day long
5:33:28we haven't typed in and run this script
5:33:30what we've been doing is we've been
5:33:31running things
5:33:32like verb dash noun verb dash noun
5:33:36god i'd like to do the same thing too if
5:33:38only i knew how
5:33:40well here's how i'm going to add one
5:33:43more keyword
5:33:45to your day of fun function you need to
5:33:49give it a name now we're going to give
5:33:51it a proper name
5:33:52verb dash now don't do this
5:33:57gimme dash stuff no
5:34:00gimme is not on the improved verb list
5:34:02so knock it off with making up your own
5:34:04verbs
5:34:04there's and everybody uh you got to do
5:34:07it at least once right but here we're
5:34:08going to do get dash and we're just
5:34:10going to call it disk info
5:34:12now the function it has an open squiggly
5:34:14and then when you're done with your code
5:34:16all the way at the end
5:34:17but wait what we're going to we're going
5:34:19to do i see later
5:34:21we going to do what we're going to talk
5:34:22about ise a lot next time
5:34:24yeah oh yeah yeah yeah yeah what do you
5:34:26what do you want him to see get rid of
5:34:27the last squiggle
5:34:29the the last one get rid of the last
5:34:31squiggle
5:34:32okay see the first squiggle see that
5:34:33squig see the red oh yeah yeah
5:34:36missing clothes so it's trying to help
5:34:39us
5:34:40understand where we're making that cool
5:34:41so you see that little squiggle it's
5:34:43actually pretty useful
5:34:44and you guys see on the screen the
5:34:45little red squiggly that jeffrey's
5:34:46talking about is this one right here and
5:34:48so if you leave your mouse over it it
5:34:49tells you
5:34:50hey you're missing something here bro
5:34:52and in this case dude
5:34:54dude and so we're we're missing that
5:34:56bottom squiggly now really going to like
5:34:58two
5:34:59yeah exactly so i'm going to
5:35:02indent this so that it's easier to read
5:35:05so you can see that i have a function
5:35:06now
5:35:08don't do what i'm about to do because
5:35:10this is just i'm going to show you
5:35:11something much cooler than this i'm
5:35:12going to save this
5:35:13and i want to show you here's one of the
5:35:15interesting things
5:35:17i'd like to run that script and then use
5:35:18that function well
5:35:20here's the challenging thing watch if i
5:35:22run disk info and i hit enter
5:35:24what happens when you run a script is
5:35:26the script runs it executes
5:35:28and then everything is discarded out of
5:35:30memory this is a good thing
5:35:32but here's the problem i just ran a
5:35:34script and it has a function called get
5:35:36disk info
5:35:37so what happened is the script just ran
5:35:39it just made this function up in memory
5:35:41for me
5:35:42and when the script ended it just killed
5:35:45it
5:35:46so there is no get disk info no no so
5:35:48i'll
5:35:49show you a unique way to do this now
5:35:51this is a great way for testing but i i
5:35:52got a better solution for you
5:35:54dot space
5:35:58i know i love it no it's awesome this
5:36:01retains the stuff in your script in
5:36:04memory so watch i'm going to run it it's
5:36:06not the right explanation okay but
5:36:08to tell them okay so here's the way it
5:36:10works so what happens is there's a stack
5:36:12right and so what happens is uh when you
5:36:15run something in general
5:36:16you create a new stack and you put all
5:36:19your variables in that stack
5:36:21and then when you do an exit or a return
5:36:23that stack goes away and they all get
5:36:24cleared up
5:36:26when you dot something what happens is
5:36:28it runs it doesn't create a new stack
5:36:30it runs it in the current stack so any
5:36:32new variables or anything that gets
5:36:34created they get created here when you
5:36:36exit you just exit but they stick around
5:36:38they stick around so
5:36:42dot sourcing and your unix guys will you
5:36:45like cotton right onto this this is
5:36:46dot source isn't that what i said only
5:36:48not nearly as well as you said it
5:36:50okay okay so watch get disk watch i'm
5:36:53going to hit tab completion at this
5:36:55point get disk
5:36:56get disk image hey tab completion
5:36:59it look looks like a commandlet lookie
5:37:02look at computer name dc
5:37:04we are rock and roll
5:37:08i don't like having to do this dot
5:37:09source stuff probably did you
5:37:11you when you hit that command line wait
5:37:12wait do it again do it again
5:37:14up arrow up there dash
5:37:18o tab
5:37:21ooh oh out oh out variable so
5:37:25let's um hey what do you want to call it
5:37:27a hey everything's a
5:37:28everything's a no dallas on a no dollar
5:37:30sign a so now i don't you guys see that
5:37:33it just sent it out to the variable it's
5:37:35some of those common parameters that we
5:37:36can use so now we've got
5:37:38this stuffed into a variable it's
5:37:39awesome so what that meant was when you
5:37:41put that commandlet binding there
5:37:43it said common parameters there's a
5:37:45bunch of common parameters and these are
5:37:47functions
5:37:48you know just by putting that one thing
5:37:49and you say hey powershell engine could
5:37:51you do some stuff work for me
5:37:52could you like give them output variable
5:37:55and then could you do like error action
5:37:57an error variable and warning action and
5:37:59warranty variable
5:38:00oh really cool stuff well you know let's
5:38:03take this one step further and you and
5:38:04you
5:38:05can certainly throw uh stuff into this
5:38:07but but guys this is going to be the
5:38:09meat of of what we
5:38:10we do on august uh first yeah and that's
5:38:14you know this is nice but this isn't
5:38:16something quite
5:38:17yet what we refer to as an advanced
5:38:19function although it's getting there
5:38:21and what i want to be able to do is i
5:38:22don't want to have to dot source
5:38:24and run this as a script that doesn't
5:38:25make sense to the junior admin that i
5:38:27want to give this to
5:38:28it's really worth the investment it's
5:38:30going to take some time right it's not
5:38:32going to be the simplest thing in the
5:38:33world
5:38:33it's going to take some time but you
5:38:34really need to invest in learning about
5:38:36modules okay because modules are the
5:38:39future they're really worth the
5:38:40investment
5:38:41yes you know why don't we just like
5:38:43settle in and teach them how to do it
5:38:45and teach them how to do it so you guys
5:38:47ready hardcore here we go yeah we're
5:38:49gonna hardcore we're gonna make a module
5:38:50wake up first of all i'm gonna show you
5:38:53the cheesy way to make a module
5:38:54nope cheesy file save as
5:38:59notice my my script
5:39:06that's that's it that's that's that's it
5:39:08that's that's that's it that's that's
5:39:10how you make them out you psm
5:39:12one watch what watch out what what
5:39:16you can now go to sleep yeah you can
5:39:17wait watch watch
5:39:19now now look because it's not in the
5:39:21special place
5:39:22that we're going to talk about i'm going
5:39:24to have to manually import this module
5:39:26and this module is called psm1
5:39:31so this is kind of like the old v2 way
5:39:33we'd always have to
5:39:34do that but watch
5:39:38do it again
5:39:42verbose you want to do dash force that
5:39:46does it again
5:39:46for us force the other force the other
5:39:49force and then dash for both for both
5:39:51and just this just
5:39:52shows you yeah see ah
5:39:55removing one important oh i love that i
5:39:57love that so yeah it's importing the get
5:39:59disk info
5:40:00and this is actually when you especially
5:40:02especially on august 1st when we're
5:40:04working with you know you have to you
5:40:05have to reload modules you have to do
5:40:07this is actually very useful to have
5:40:09around so i've got a module that's
5:40:11imported now i can just do get disk info
5:40:13but you know
5:40:15this is still not exactly the way that i
5:40:18want it because i don't want to have to
5:40:20say here's this thing i made you this
5:40:22pretty
5:40:23module it's a psm1 file and i
5:40:26you're going to have to import it every
5:40:27time you want to use anything in it that
5:40:29just doesn't make sense
5:40:31dude so hard was that it was easy i know
5:40:33it was easy but you guys have like
5:40:34magical locations
5:40:36oh there is the magic yeah yeah so it's
5:40:38going to let them in on the secrets well
5:40:39i don't know i
5:40:40see um env
5:40:43is it ps module path it shows us all the
5:40:45magic
5:40:46so there are two paths here
5:40:50these are the magic locations right now
5:40:52as far as we're going to talk about the
5:40:53magic locations
5:40:55if you put your module in these
5:40:57locations in a special way
5:41:00they too will be dynamically loaded dude
5:41:02what are you doing there that's odd
5:41:04i never do it that way what do you want
5:41:06to do show it my way
5:41:07okay we'll do it your way
5:41:10okay so what i do is i do i do oh
5:41:14let's make this bigger i do dollar sign
5:41:18okay and that looks the same but check
5:41:21this out because we need to do dollar
5:41:22signs dollars
5:41:25split do it your way yeah
5:41:30and then you break it out now you can
5:41:31read it yeah let's do it that way let's
5:41:33do it
5:41:34back to him split up so i can't spell
5:41:37split i can spell spit apparently
5:41:40and what are we we're doing on what the
5:41:41semicolon yeah
5:41:43there's quotes a quote it's called it's
5:41:45called it's quotes
5:41:46ah oh now we can read the two paths this
5:41:51makes a lot
5:41:52much better so here's the first path
5:41:54that i want you guys to take notice of
5:41:56this is the path and i'm going to show
5:41:57this to you graphically for a second
5:41:59just so you can kind of see this i'm
5:42:00going to go out
5:42:01this is where powershell gets installed
5:42:03windows system 32
5:42:05and there's a reason i'm showing it
5:42:06graphically sometimes this makes more
5:42:07sense
5:42:08and so i'm going to go out where it says
5:42:09windows powershell
5:42:13and you'll see this folder called
5:42:15modules you see all these modules
5:42:17these are modules here's the thing don't
5:42:20put yours here
5:42:20yeah this is not for you a lot of guys
5:42:23will say oh just put it in there because
5:42:25i
5:42:25know where it is all that kind of stuff
5:42:26no don't put your stuff there this is
5:42:28the special place for microsoft
5:42:30you have your own special place
5:42:34and that is this one
5:42:38your account documents windows
5:42:40powershell modules but
5:42:41this doesn't exist let me show you let
5:42:44me show you graphically sometimes this
5:42:46makes a little bit more sense so i'm
5:42:47going to
5:42:48go out here to users
5:42:51and i'll go out to student company is my
5:42:54account and it's my documents through
5:42:56here
5:42:57you see there's no module called a
5:42:59windows powershell and there's nothing
5:43:01called
5:43:03modules so you will need to make it now
5:43:05i i know
5:43:06i'm making it graphically just because i
5:43:07happen to be here but
5:43:09you can do it with powershell of course
5:43:11windows powershell
5:43:13and then underneath of it you make
5:43:17it been faster if i'd done it in
5:43:18powershell oh my god what the hell's the
5:43:20matter with me
5:43:21so modules because now you're going to
5:43:23have to type it right now i'm going to
5:43:24have to type it right now here's the
5:43:25thing
5:43:26and this is very very important the name
5:43:30of your module you know the thing i call
5:43:33diskinfo.psm1
5:43:35needs to be the name of the folder that
5:43:37you're going to create here they need to
5:43:39match
5:43:40so i'm going to say new folder
5:43:44i'm going to say disk info now
5:43:47i've got this folder let's do this
5:43:51i need to put my module in there so let
5:43:54me go grab my module
5:43:56which was this psm1 disk info
5:44:00i'm gonna take it put it out to here
5:44:03oh yeah i should have never done this
5:44:05graphically but now i'm here
5:44:07i'm gonna put it now here's the
5:44:09important thing see look module name
5:44:12the the module folder name and then
5:44:16the name of the duder inside watch
5:44:19let's close this so you know i'm not
5:44:21cheating
5:44:24let's see i wonder if i can get some
5:44:26help on
5:44:28uh did you start a fresh window yeah i
5:44:30started a brand new one
5:44:31a brand new one oh here just in case
5:44:33anybody missed it i don't want you to
5:44:34miss it i'm not cheating let me close
5:44:36this thing up
5:44:36i'm not cheating brand new window
5:44:40get help um is there anything
5:44:43uh in commandlet's on disk information
5:44:48hmm wait wait wait wait wait
5:44:52oh
5:44:54[Music]
5:44:58inside my module and well let's just try
5:45:00it get uh
5:45:01disk uh info or not image info
5:45:05dash computer name dc
5:45:08oh okay
5:45:12you can tell that we're getting up to
5:45:13the end of the day because the guys
5:45:15in the back are are now going oh
5:45:19so let me let me let me just show you
5:45:21the uh the code again
5:45:22and jeffrey please go ahead and add in
5:45:24so all you're really doing is
5:45:26doing functions we're properly naming
5:45:28them so that they look like commandlets
5:45:29notice
5:45:30i just gave it a little bit of help
5:45:31there are about underscore comment based
5:45:33help
5:45:34files for this to help you with this or
5:45:36you can use
5:45:37ctrl j to get the snippets and notice i
5:45:40took a working line of code
5:45:42the only thing i did was i added param
5:45:45a couple of variables in there maybe an
5:45:47attribute and believe me on august 1st
5:45:49we'll talk a lot more about attributes
5:45:51that speeds rock
5:45:52oh they totally rock so with this simple
5:45:54little bit of code
5:45:55and saving it in the special place as a
5:45:57psm1 file
5:45:59i've made a module in fact in like all
5:46:02modules
5:46:02i'm not just going to put one function
5:46:04in here i'm going to put as many
5:46:06functions i'm going to make as many
5:46:08tools
5:46:09as i need and i'm going to put them into
5:46:11this module so just
5:46:13i'll just make it foo and i'll make
5:46:15function
5:46:16bar no i know they're not properly named
5:46:19but
5:46:20you get the idea now in that with that
5:46:22module i'm just adding more and more
5:46:24tools to this module now can do that
5:46:26save it save it save it
5:46:30uh so um important
5:46:33import import module and it's uh
5:46:36i forgot the name of disc info right and
5:46:38then we want to s force
5:46:40force and verbose or that's fine
5:46:45hmm oh did you expect it to come up and
5:46:48do the whole
5:46:48you're using a yeah not improved you
5:46:51know
5:46:51what he's talking about is and matter of
5:46:53fact i have to play with this i think
5:46:56well let's do uh gimme dash
5:47:00foo and uh
5:47:04yeah yeah bar dash foo and let me save
5:47:08it
5:47:13oh you know it's the force that's the
5:47:15problem oh it's the force that's doing
5:47:16it
5:47:16so move it remove it so module remove
5:47:19module
5:47:20by the way so force basically says i
5:47:23you're telling us
5:47:24we know what you're doing ignore all the
5:47:27errors just do what i told you to do
5:47:29dang it so watch what happens if you
5:47:31don't type force
5:47:32and this is actually uh disk info
5:47:38oh dude i don't know why it's i'm not
5:47:40saying it okay
5:47:41i don't know why it's not saying but
5:47:42here's what usually happens if you use
5:47:44an unapproved verb it comes up and it
5:47:46says in yellow
5:47:47knock it off stop using unapproved verbs
5:47:49don't be a dope
5:47:50don't be a dope so use the proved verbs
5:47:52and what are we doing on this uh
5:47:54today i see something up it gives us uh
5:47:57oh oh oh i they were trying to
5:48:01you guys don't understand what's up on
5:48:02the teleprompters in here right now
5:48:05the guys the production team was trying
5:48:07to be effing
5:48:08funny they didn't use the appropriate
5:48:11verb
5:48:11and so first of all here's what they
5:48:13typed in so you all can see it they said
5:48:16dollar sign mentioned this
5:48:19pipe to and i can't even read what
5:48:22character they're using
5:48:23this is were you guys up on
5:48:26site um and then was it a squiggly
5:48:30uh squiggly um it gives
5:48:35us good feedback
5:48:38in squeeze this is this is have you guys
5:48:40been awake at all today this is the
5:48:41crappiest powershell i've ever seen
5:48:47this is remarkable we've been we've been
5:48:50busting our bums all day long
5:48:52and you type this in please
5:48:55one of the mvps in the forums somebody
5:48:57you don't even be an mvp
5:48:58you take this and show them how it
5:49:00really should be done in the cliff note
5:49:02version
5:49:02yeah but the point is i thought we had a
5:49:05goodwill hunting moment there
5:49:08not so much that's good yeah here you go
5:49:12stay in av um what i think they're
5:49:15trying to say is that there's a poll
5:49:17up am i correct there's a poll up and
5:49:19it's a real important poll
5:49:21so make sure you you do the poll up on
5:49:23the site because the feedback
5:49:25for this session is is very important as
5:49:27a matter of fact we're we're starting to
5:49:29get kind of towards the end of
5:49:31what we we've done for the the day but
5:49:33your feedback on the session is very
5:49:35important
5:49:35um just so that you know we're going to
5:49:39dive
5:49:39deep deep deep and we're going to do it
5:49:41in a day so it's going to be
5:49:43definitely a day chewy chewy stuff
5:49:46into tool making basically making uh
5:49:49tools is going to show the different
5:49:51kind of parameter attributes
5:49:53more about the help how to see we've
5:49:56only scratched the surface
5:49:58our commandlet right now doesn't accept
5:50:01pipeline
5:50:01input it's not making changes so we're
5:50:04not supporting what if and confirm
5:50:07and you know we might want to make our
5:50:09own views we there's so many things that
5:50:12we're going to want to do
5:50:14so we've actually still got a lot of
5:50:16work to do we're just not going to do
5:50:17much more of it
5:50:19today so before we do a review
5:50:23is there anything you want to add to the
5:50:24stuff that we've done today is it
5:50:25telling you
5:50:26i think we i think we've been having fun
5:50:28we've walked through a bunch of stuff
5:50:29ton more
5:50:30ton more but again the key things i want
5:50:32you guys to to walk away with are
5:50:35one uh this spirit of exploration
5:50:38right go explore explore the help
5:50:41explore the help
5:50:42do you explore the help explore the
5:50:44forums go on the internet try some
5:50:46things
5:50:47and when you get confused ask questions
5:50:50do not be embarrassed not sit there say
5:50:52oh that's a dumb question no
5:50:53no ask that question you have a great
5:50:56community that will give you help
5:50:58and just a is hopefully you've seen the
5:51:01sense of fun
5:51:02there's just an incredible amount of
5:51:03power in powershell
5:51:05and it's fun to do this exploration by
5:51:07the way and it's safe too
5:51:08because you know you go and you have the
5:51:10minus what if and the
5:51:12and the uh confirm and verbose so you
5:51:15know it's uh you can explore and you can
5:51:17have fun and
5:51:18and do it safely and do it safely and it
5:51:21noticed that we've been having a lot of
5:51:22fun today because it's been a joy for
5:51:24the two of us to be able to spend the
5:51:25day talking with everybody about
5:51:27powershell
5:51:27because it is just a lot of fun
5:51:29especially when you get past some of the
5:51:31learning curve stuff
5:51:32so you we did get help and the the
5:51:34amazing discoverability of get help
5:51:37of finding commandlets regardless of
5:51:39what product that you're working with
5:51:40it'll find it for you
5:51:42and then you can go into the help files
5:51:44the examples the rich
5:51:46the syntax that's in there the
5:51:47definitions of the parameters
5:51:49so get help is definitely number one
5:51:52tool
5:51:53something you definitely want to get
5:51:54good at though is that middle piece we
5:51:56did just after the meal break
5:51:59of understanding the pipeline and how
5:52:01the pipeline works because
5:52:03if you can't figure out how to get two
5:52:05commandments to work together
5:52:07you're just not going to have a lot of
5:52:09fun that's so very important so
5:52:11remember don jones has a great book on
5:52:13learn windows powershell in the month of
5:52:14lunches it's chapter nine i know it
5:52:16sounds like i'm trying to sell a book i
5:52:17just want you to have
5:52:18more resource information on working
5:52:21through that and go out to the forums on
5:52:23powershell.org and ask about that
5:52:25also the thing that really changes and i
5:52:27i have to say
5:52:28you know understanding the pipeline that
5:52:31made a huge difference for me
5:52:33when v2 shipped and remoting that's what
5:52:36changed
5:52:37administration for me and it's changed
5:52:39it forever
5:52:40the remoting being able to hit multiple
5:52:43machines being able to do
5:52:44multiple things at once being able to
5:52:46put those into scripts
5:52:49has really really made a huge a huge
5:52:51difference
5:52:52so that's the stuff everybody you know
5:52:53powershell is running all of our
5:52:54websites
5:52:55you know all of our big internet sites
5:52:57and then that's why
5:52:58because i got a gazillion of these
5:53:00things how am i going to do things how
5:53:01am i going to do things and i think you
5:53:02guys have seen today
5:53:03a great example that powershell you can
5:53:06learn it you've learned a lot of it
5:53:07today
5:53:08and you know what i didn't tell them
5:53:09about what did you tell our sacred vow
5:53:12the sacred vow so uh so here's the
5:53:15sacred vowel the whole story behind the
5:53:16sacred vowel the sacred vowel is
5:53:17basically the story that says
5:53:19hey you're i.t pros your hair's on fire
5:53:21the last thing the world
5:53:22we know the last thing in the world you
5:53:23want to do is take your time to go
5:53:25learn a new tool and yet here i am and
5:53:28i'm sitting here asking you
5:53:29to learn this new tool and why and the
5:53:32answer is because it's going to help you
5:53:35and there's a set of things that you
5:53:36have to learn you have to learn the
5:53:38verbs you have to learn the syntax
5:53:39i have to learn the pipeline and you
5:53:41have to learn how to do things how to
5:53:43explore et cetera
5:53:44but my sacred vow to you is that if you
5:53:47learn those things
5:53:48i'm going to do everything in my power
5:53:50to reuse those words
5:53:52those concepts those techniques over
5:53:55and over and over and over again so that
5:53:58your investment in learning
5:54:00is the best payback the best investment
5:54:03you ever made
5:54:04now let me get concrete about what that
5:54:06means when we decided hey we need to
5:54:08support
5:54:08workflow the original design for
5:54:11workflow was this very unusual thing
5:54:13oh you know you got some weird syntax
5:54:15for workflow
5:54:16steps and workflow sequences
5:54:19and all that i said guys whack you
5:54:22forgot our sacred vow
5:54:24our sacred vow is they've already
5:54:25learned powershell use that over and
5:54:28over and over again
5:54:29so now when you when we teach you about
5:54:31workflow what you're going to see is
5:54:32you just type instead of function foo
5:54:35you type workflow
5:54:36foo and then you write powershell
5:54:39and the difference is that now it looks
5:54:42just like powershell
5:54:43except it's got very different semantics
5:54:45it isn't run
5:54:46by the traditional powershell engine we
5:54:49take that powershell syntax
5:54:51and we transcode it into a windows
5:54:54workflow
5:54:54object graph and we give it to the
5:54:56windows workflow
5:54:57engine to execute its execution engine
5:55:00but you
5:55:01your experience looks just like
5:55:04powershell even though underneath the
5:55:05covers
5:55:06it's very very different why because of
5:55:08our sacred vow
5:55:10you learn this stuff and we're going to
5:55:11do it over and over and over again
5:55:14use those techniques over and over and
5:55:15over again you learn how to manage
5:55:17exchange you're going to be able to let
5:55:18manage link having learned
5:55:20those two things you're going to be able
5:55:22to learn how to manage azure and
5:55:25sql and all that because of the sacred
5:55:27vow and we take that
5:55:28super seriously and i have to say it's
5:55:30it's a great honor to sit here next to
5:55:32jeffrey snover and it's been a great
5:55:33honor to be able to talk with with
5:55:35members of the powershell team because
5:55:36guys
5:55:37you got to realize that sacred vow
5:55:38they've stuck to it they've
5:55:40stuck to it over the over several you
5:55:42know the last five six years that i've
5:55:44been doing this
5:55:45there's one guarantee that i've always
5:55:47had and that's if i'm going to take
5:55:49the investment to learn this they're not
5:55:50going to screw me on the back end by
5:55:52suddenly
5:55:52ripping everything out replacing it and
5:55:54totally changing everything nope
5:55:56i'm going to get commandments i'm going
5:55:57to get parameters i've got a scripting
5:55:59environment that makes sense that's
5:56:00stable
5:56:01that's being moved forward it's always
5:56:03going to be improved but
5:56:04i know exactly what to expect and i know
5:56:06what to expect
5:56:07when i go to active directory to manage
5:56:09exchange to manage whatever
5:56:11it's the same and that experience makes
5:56:14this initial investment
5:56:16a little painful at first but it will
5:56:18pay off and it'll pay off
5:56:20for years and years and years and you've
5:56:22heard it from the architect they are
5:56:24so totally committed to that so
5:56:28a little bit of information of how you
5:56:30get some more information so let me just
5:56:32uh
5:56:33yeah we're going to leave your guys's
5:56:35mistake up on there a very embarrassing
5:56:37thing that you did
