I am on a master branch \'master\' and I have 1 commit ahead I want to create a new remote branch called \'new_remote\' and push my commit there?
$ git branc
I think you just want to push your changes, so:
git push old_remote master
should be enough for you. The first parameter for git push is the remote you want to update (in your case that's old_remote') and the second is the branch you want to push.
Instead of specifying branch with name, you can use --all like this:
git push old_remote --all
