1. 0:06Hey.
2. 0:07And welcome my little park champs to the
3. 0:10second video of your very first machine
4. 0:12project.
5. 0:13Uh Shell00. I'm Marilyn. I'm 22 years
6. 0:17old. Been a coder I'm since uh last
7. 0:19October and I really like frogs among
8. 0:22other things.
9. 0:24Uh if you haven't seen uh last video, I
10. 0:26recommend you watch that one first.
11. 0:28Hopefully, you're a bit more comfortable
12. 0:30uh using shell commands now. And in
13. 0:32today's video, I'm going to try and
14. 0:33teach you about Git.
15. 0:35Um so, what is Git? It's basically a set
16. 0:38of commands programmers can use to
17. 0:39easily make backups of uh all of their
18. 0:42code. In the industry, it's also used
19. 0:44for a bunch of other things.
20. 0:46Uh big one managing big projects where a
21. 0:48bunch of people are working on the same
22. 0:50code.
23. 0:51Um but we're not going to talk about any
24. 0:52of that. I'm going to keep it as simple
25. 0:54as possible for this video and just show
26. 0:57you what you need to know to be able to
27. 0:59work on your projects. Um
28. 1:01that being the case, if you see anything
29. 1:03and you're curious about something, like
30. 1:05why why do I need to do this or that, I
31. 1:08do encourage you um if you have the time
32. 1:11to look uh any of those things up.
33. 1:14Um all right. Let's uh dive in, shall
34. 1:17we?
35. 1:19Um so, as you can see, I just registered
36. 1:22for Shell00. If you haven't done that
37. 1:25yet, I recommend you do the same.
38. 1:27Um and then
39. 1:29a little um Git repository will be
40. 1:33generated for you.
41. 1:35Uh after a minute or so.
42. 1:38What is a repository? You can basically
43. 1:40just see it as a little folder
44. 1:42um
45. 1:43for your project. So, what um
46. 1:46what we're going to do, we're going to
47. 1:47clone everything that's in that folder
48. 1:49and then we can add stuff to it uh
49. 1:52whatever we want and then we can sync
50. 1:54all those changes back onto Git.
51. 1:56Um so, the first thing you would usually
52. 1:59do
53. 2:00you would use Git clone
54. 2:02then the link and if you would like you
55. 2:05can even give it your own custom name.
56. 2:09But for us right now it won't work quite
57. 2:11yet.
58. 2:12This is because we need the rights for
59. 2:15it
60. 2:16and how this works with 42
61. 2:18is we need SSH key in our intra. It's
62. 2:21just for safety reasons.
63. 2:23Luckily I will show you how to do that
64. 2:25too.
65. 2:28We are going to use the command SSH
66. 2:30keygen.
67. 2:31And then we can just press enter three
68. 2:33times.
69. 2:34And then it will generate as you can see
70. 2:38a couple of keys right here in our home
71. 2:40folder.
72. 2:41I'll show you what it looks like.
73. 2:45.ssh
74. 2:49And
75. 2:52voila.
76. 2:54Now you see two keys, two ideas. The
77. 2:57normal one is your private key. You can
78. 2:59see this as your PIN code or bank
79. 3:01number. Basically what I'm trying to say
80. 3:03that's something you shouldn't ever
81. 3:04share.
82. 3:05So for your own good please don't.
83. 3:08And the other one the dot pub that's our
84. 3:10public key key and luckily we can share
85. 3:13that one with anyone that we want to
86. 3:15allow to work on our projects.
87. 3:20So we're going to cut this.
88. 3:22And then if you don't know what that
89. 3:23does it will show you all the contents
90. 3:25of the file in this case the key.
91. 3:28And then we're simply going to head over
92. 3:29to intra
93. 3:31into our settings.
94. 3:35And then we're going to go
95. 3:37to our key.
96. 3:39I'll remove this one
97. 3:41and make a new one
98. 3:43right here.
99. 3:45Voila.
100. 3:48Let's call it
101. 3:50cool key.
102. 3:53Perfect.
103. 3:58Um now we can go back.
104. 4:02And we will I will make a little folder
105. 4:03right here just just for now.
106. 4:07Um video
107. 4:11and in set directory, we can now
108. 4:19use our Git clone.
109. 4:25And it will work.
110. 4:28We will
111. 4:29go right into there.
112. 4:31As you see, our fancy uh terminal font
113. 4:34already shows that that it's a little
114. 4:36Git repository.
115. 4:38I don't have to worry if yours doesn't
116. 4:40do that. It's just uh
117. 4:42uh for clarity's sake. Ours already has
118. 4:45a couple of files added,
119. 4:47um but what I'm going to show you is if
120. 4:49you want to make if you make more files
121. 4:51or you're doing your programming work,
122. 4:53whatever it is that you do,
123. 4:55um
124. 4:59and you add a file,
125. 5:01uh and let's say you're done and you
126. 5:03want to make a backup, um I'm going to
127. 5:05show you how to do that, too.
128. 5:07There's basically four steps to it
129. 5:09um and four commands. The first one um
130. 5:12that's good to know is Git status.
131. 5:14This shows you um basically whatever
132. 5:17files are there and which ones are
133. 5:19tracked and which ones in that aren't.
134. 5:22Uh so you can basically use it to keep
135. 5:23track on if everything's up to order.
136. 5:26The second one is Git add. In this case,
137. 5:29we're going to add hi.
138. 5:31You will also see if I use status again,
139. 5:33you can see it's added to the track
140. 5:35list.
141. 5:36Our third one is Git commit.
142. 5:39This is basically giving Git a little
143. 5:41heads up that there are changes and that
144. 5:43they've been made and they will soon be
145. 5:45pushed.
146. 5:46Um
147. 5:47and we use a little {dash} m uh to make
148. 5:50adding them
149. 5:51to make adding the message a little
150. 5:53easier.
151. 5:54Um
152. 5:56added hi.txt
153. 5:59And it's good practice to um try to make
154. 6:02whatever commit message you do
155. 6:04indicative or
156. 6:06um show what kind of changes you made.
157. 6:08For the piscine, this doesn't really
158. 6:09matter, but it's good to already sort of
159. 6:11get used to it.
160. 6:13Um perfect.
161. 6:15And our last but not last but not least,
162. 6:18our last command, get push,
163. 6:22simply pushes all of the changes you
164. 6:24made on your local computer onto
165. 6:26whatever server or place um the Git
166. 6:29repository is on.
167. 6:31So, that's all perfect.
168. 6:33Um and now if we would like,
169. 6:36I can show you even that it worked.
170. 6:39Let's make another
171. 6:41um
172. 6:42Let's clone another instance.
173. 6:51Voila.
174. 6:53And if we go into there,
175. 6:55you can now see, as before, it already
176. 6:57had two files in them, but our hi.txt is
177. 7:00in there, too, now.
178. 7:01Um so, yeah.
179. 7:04This
180. 7:05uh that's basically it for now.
181. 7:07Um hope you learned. Hope it was uh
182. 7:09understandable.
183. 7:11And uh I wish you the best of luck on
184. 7:13your piscine journey.
185. 7:15Ciao.
