Set up a git repository

There are a couple ways to setup a git repository depending on what type of work you are trying to do.

  1. Single repository which is used by you and no one else

  2. Group repository which is used by you and someone else in your group

  3. Public repository which is readable (and clonable) by anyone


To setup a single repository, you can simply change to the directory which you want to be under git control and do the following:

git init
git add .
git commit -m "Initial import"

This will give you a git repository which you can then clone remotely using ssh.


To setup a group repository, you will need to use a directory which is readable/writable by all the members of your group. This can usually be found in your center or program shared storage. You will need to initialize a bare shared group repository. The following example is assuming your shared storage is at /org/centers/foo and your project name is bar:

GIT_DIR=bar.git git init --bare --shared=group
Initialized empty shared Git repository in /org/centers/foo/repos/private/bar.git/

You can now clone your new repository by doing the following:

git clone /org/centers/foo/repos/private/bar
Initialized empty Git repository in /tmp/bar/.git/
warning: You appear to have cloned an empty repository.

You can now begin adding things to the bar directory and committing them. When you are ready to push your changes to the central repository, you can do:

git push --all
Counting objects: 3, done.
Writing objects: 100% (3/3), 235 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
To /org/centers/foo/repos/private/bar
 * [new branch]      master -> master

As you can see, the --all created the remote master branch for you. In the future, all you will need to do is git push.


You can determine your group membership by using the id command on any Oden Institute machine. Your gid is your primary group and the other groups listed are supplementary groups to which you have been added based on your affiliation.
