Git: Pushing to two repos in one command

Question

I want to do git push origin and git push my_other_remote in the same line. Possible?

Answer 1

You can get the same effect by adding an extra push URL for your origin remote. For example, if the URLs of your existing remotes are as follows:

$ git remote -v
origin  me@original:something.git (fetch)
origin  me@original:something.git (push)
my_other_remote git://somewhere/something.git (fetch)
my_other_remote git://somewhere/something.git (push)

You could do:

 git remote set-url --add --push origin git://somewhere/something.git

Then, git push origin will push to both repositories. You might want to set up a new remote called both for this, however, to avoid confusion. For example:

 git remote add both me@original:something.git
 git remote set-url --add --push both me@original:something.git
 git remote set-url --add --push both git://somewhere/something.git

... then:

 git push both

... will try to push to both repositories.

Answer 2

You can put the following in the .git/config file:

[remote "both"]
    url = url/to/first/remote
    url = url/to/other/remote

You can now push to both urls using git push both.

If you also want to fetch from them (useful for sync) you may add the following lines in your .git/config file:

[remotes]
    both = origin, other

Now you can also run git fetch both.

Answer 3

Just a small addition to the excellent answers provided already - if you dont want to bother with adding "both" and just want to have all operations pushed to both repos automatically, just add your second repo as another url under origin in the git config.

[remote "origin"]
    url = someUrl.git
    url = secondUrl.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master

Now "git push" uses both.

Answer 4

In recent versions of Git you can add multiple pushurls for a given remote. Use the following to add two pushurls to your origin:

git remote set-url --add --push origin git://original/repo.git
git remote set-url --add --push origin git://another/repo.git

So when you push to origin, it will push to both repositories.

UPDATE 1: Git 1.8.0.1 and 1.8.1 (and possibly other versions) seem to have a bug that causes --add to replace the original URL the first time you use it, so you need to re-add the original URL using the same command. Doing git remote -v should reveal the current URLs for each remote.

UPDATE 2: Junio C. Hamano, the Git maintainer, explained it's how it was designed. Doing git remote set-url --add --push <remote_name> adds a pushurl for a given remote, which overrides the default URL for pushes. However, you may add multiple pushurls for a given remote, which then allows you to push to multiple remotes using a single git push. You can verify this behavior below:

$ git clone git://original/repo.git
$ git remote -v
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.'
remote.origin.url=git://original/repo.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*

Now, if you want to push to two or more repositories using a single command, you may create a new remote named all (as suggested by @Adam Nelson in comments), or keep using the origin, though the latter name is less descriptive for this purpose. If you still want to use origin, skip the following step, and use origin instead of all in all other steps.

So let's add a new remote called all that we'll reference later when pushing to multiple repositories:

$ git remote add all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)               <-- ADDED
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git            <-- ADDED
remote.all.fetch=+refs/heads/*:refs/remotes/all/* <-- ADDED

Then let's add a pushurl to the all remote, pointing to another repository:

$ git remote set-url --add --push all git://another/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)                 <-- CHANGED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git         <-- ADDED

Here git remote -v shows the new pushurl for push, so if you do git push all master, it will push the master branch to git://another/repo.git only. This shows how pushurl overrides the default url (remote.all.url).

Now let's add another pushurl pointing to the original repository:

$ git remote set-url --add --push all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git
remote.all.pushurl=git://original/repo.git        <-- ADDED
You see both pushurls we added are kept. Now a single git push all master will push the master branch to both git://another/repo.git and git://original/repo.git.

IMPORTANT NOTE: If your remotes have distinct rules (hooks) to accept/reject a push, one remote may accept it while the other doesn't. Therefore, if you want them to have the exact same history, you'll need to fix your commits locally to make them acceptable by both remotes and push again, or you might end up in a situation where you can only fix it by rewriting history (using push -f), and that could cause problems for people that have already pulled your previous changes from the repo.
