Creating remote GIT branch

You can create a new local branch like this:

git checkout -b <branch_name>

If you want to make it a remote branch, then it can be pushed to remote like this (make sure that you're in this new branch):

git push origin <branch_name>

But sometimes, this newly pushed branch to remote doesn't get updated on remote location. Remote branches could be forced refreshed like this:

git remote update origin --prune 

If you want to delete a local branch:

git branch -d <branch_name>

If you want to delete this branch in remote too, then:

git push origin :<branch_name>
