Create a remote branch GIT

First, you create your branch locally

git checkout -b your_branch

The remote branch is automatically created when you push it to the remote server. So when you feel for it, you can just do

git push <remote-name> <branch-name>

Where <remote-name> is typically origin, the name which git gives to the remote you cloned from. Your colleagues would then just pull that branch, and it's automatically created locally.

Note however that formally, the format is:

git push <remote-name> <local-branch-name>:<remote-branch-name>

But when you omit one, it assumes both branch names are the same. Having said this, as a word of caution, do not make the critical mistake of specifying only :<remote-branch-name> (with the colon), or the remote branch will be deleted!

So that a subsequent git pull will know what to do, you might instead want to use:

git push -u <remote-name> <branch-name>

As described below, the -u option sets up an upstream branch:

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.
