git push to multiple repositories simultaneously

How can I make git push to push not only to origin but also another remote repository?

as git push is only an alias for git push origin, can I alias git push to push to 2 remote repositories at once (with just that one command)?

I’m not looking for a non-git script here but would like to set this up for my local repository in git.

When I tried it with post-push scripts I failed.

I don't think you can do it just by setting a flag on git, but you can modify a config file that will allow you to push to multiple remote repositories without manually typing them all in (well only typing them in the first time and not after)

In the .git/config file you can add multiple urls to a defined remote:

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

If you git push all now you push to all the remote urls.

No manual editing

You can add multiple URLs to a remote branch (e.g. all) directly from command line by using git config --add remote.xyz.url with different URLs:

git config --add remote.all.url ssh://user@server/repos/g0.git
git config --add remote.all.url ssh://user@server/repos/g1.git

Fully automatic

If you're super lazy and don't want to copy/paste URLs several times, this is for you:

function git-add-push-all() {
  while read -r name url method; do
    git config --add remote.all.url "$url"
  done < <(git remote -v | awk '!/^all/ && /push/')
}

git-add-push-all # from git (sub)directory

A full bashy script is possible (test $name and $method), but awk is sweet and there is love for everyone.

Push

Then you can push to all remote with

git push all

You can also get url from configured remotes :

for repo in g0 g1 ...
do
    git config --add remote.all.url `git config remote.$repo.url`
done

where g0, g1, ... are the names of your remotes.
