git branch -m new_name

git branch -m old_name new_name

git branch -a
As you can see, only the local name changed Now, to change the name also in the remote you must do:

git push origin :old_name
This removes the branch, then upload it with the new name:

git push origin new_name

 $ git branch -m <new_name>
