How to copy a local Git branch to a remote repo

Solution 1:

According to git push manual page:

 git push origin experimental

Find a ref that matches experimental in the source repository (most likely, it would find refs/heads/experimental), and update the same ref (e.g. refs/heads/experimental) in origin repository with it.
If experimental did not exist remotely, it would be created.

This is the same as:

git push origin experimental:refs/heads/experimental

Create the branch experimental in the origin repository by copying the current experimental branch.
This form is only needed to create a new branch or tag in the remote repository when the local name and the remote name are different; otherwise, the ref name on its own will work.

Or, like mentioned in git tip, you can set up a "Branch’s Default Remote":

You can use git config to assign a default remote to a given branch. This default remote will be used to push that branch unless otherwise specified.

This is already done for you when you use git clone, allowing you to use git push without any arguments to push the local master branch to update the origin repository’s master branch.

git config branch.<name>.remote <remote> 

can be used to specify this manually.

Jan suggests (for git >= 1.7.0) the push -u (or push --set-upstream) option:

For every branch that is up to date or successfully pushed, add upstream (tracking) reference, used by argument-less git-pull(1) and other commands.

That way, you don't have to do any git config.

git push -u origin experimental

Solution 2:

If the name of your branch is experimental, and the name of the remote is origin, then it's

git push origin experimental

Solution 3:

git push -u <remote-name> <branch-name> doesn't work if the newly created branch isn't spawned from the same repo, i.e. if you haven't created the new branch using git checkout -b new_branch, then this will not work.

For eg, I had cloned two different repositories locally and I had to copy repo2/branch1 to repo1/ and then push it too.
