How do you push just a single Git branch (and no other branches)?

Question

I am working on a local git repository. There are two branches, master and feature_x.

I want to push feature_x to the remote r

Answer 1

So let's say you have a local branch foo, a remote called origin and a remote branch origin/master.

To push the contents of foo to origin/master, you first need to set its upstream:

git checkout foo
git branch -u origin/master

Then you can push to this branch using:

git push origin HEAD:master

In the last command you can add --force to replace the entire history of origin/master with that of foo.
