===== Bare Git Repository in your CS Home directory =====

[[https://git-scm.com/book/en/v2/Git-on-the-Server-Getting-Git-on-a-Server|Source documentation]]


=== SSH to a CS server ===
<code>
ssh cnetid@linux.cs.uchicago.edu
</code>

=== Initialize a bare repo in your CS home directory ===
Note that a bare repo cannot be edited directly. You will need to checkout the repository elsewhere in your home directory.
<code>
$ mkdir $HOME/gitbare/myproject.git
$ cd $HOME/gitbare/myproject.git
$ git init --bare --shared
</code>

=== Check out your repository ===

Even if you are on one of the linux.cs servers you will need to checkout the bare repo.
<code>
git clone cnetid@linux.cs.uchicago.edu:~/gitbare/myproject.git
</code>

==== Example ====
<code>
laptop:~$ ssh kauffman3@linux.cs.uchicago.edu
kauffman3@linux3:~$ mkdir myproject.git
kauffman3@linux3:~$ cd myproject.git/
kauffman3@linux3:~/gitbare/myproject.git$ git init --bare --shared
Initialized empty shared Git repository in /home/kauffman3/gitbare/myproject.git/
kauffman3@linux3:~/gitbare/myproject.git$ cd
</code>

=== Clone from inside your CS home ===
<code>
kauffman3@linux3:~$ git clone kauffman3@linux.cs.uchicago.edu:~/gitbare/myproject.git
