git, pushing to multiple repositories

I was looking for a way to keep more than one repository updated when I’m working on personal projects, don’t ask. So I found some useful information I’m going to post here for future reference.

Example part of a “.git/config” file:

[remote 'all']
    url=ssh://user@server/repos/g0.git
    url=ssh://user@server/repos/g1.git
    url=ssh://user@server/repos/g2.git
    url=ssh://user@server/repos/g3.git

With that “git push all” should push to all the remotes simultaneously.

If you have:

[branch 'master']
    remote = g0
    merge = refs/heads/master
[remote 'g0']
    url = ssh://user@server/repos/g0.git
    fetch = +refs/heads/*:refs/remotes/g0/*

Then “pulls” and "fetch"’s while on the master branch should only only target ssh://user@server/repos/g0.git.

Better yet:

[branch 'master']
    remote = origin
    merge = refs/heads/master
[remote 'origin']
    url = ssh://user@server/repos/g0.git
    fetch = +refs/heads/*:refs/remotes/g0/*

Then ssh://user@server/repos/g0.git is the default remote (“origin”) for pulls and fetches if no remote name is specified.
