Git Question

Default behavior of "git push" without a branch specified

I use the following command to push to my remote branch:

git push origin sandbox


If I say

git push origin


does that push changes in my other branches too, or does it only update my current branch? I have three branches:
master
,
production
and
sandbox
.

The
git push
documentation is not very clear about this, so I'd like to clarify this for good.

Which branches and remotes do the following
git push
commands update exactly?

git push
git push origin


origin
above is a remote.

I understand that
git push [remote] [branch]
will push only that branch to the remote.

Answer

You can control the default behavior by setting push.default in your git config. From the git-config(1) documentation:

push.default

Defines the action git push should take if no refspec is given on the command line, no refspec is configured in the remote, and no refspec is implied by any of the options given on the command line. Possible values are:

  • nothing: do not push anything

  • matching: push all matching branches

    All branches having the same name in both ends are considered to be matching.

    This is the default in Git 1.x.

  • upstream: push the current branch to its upstream branch (tracking is a deprecated synonym for upstream)

  • current: push the current branch to a branch of the same name

  • simple: (new in Git 1.7.11) like upstream, but refuses to push if the upstream branch's name is different from the local one

    This is the safest option and is well-suited for beginners.

    This will become the default in Git 2.0.

The simple, current and upstream modes are for those who want to push out a single branch after finishing work, even when the other branches are not yet ready to be pushed out

Command line examples:

To view the current configuration:

git config --global push.default

To set a new configuration:

git config --global push.default current
