# Rename the local branch to the new name
git branch -m $old_name $new_name

# Delete the old branch on remote

# Otherwise, git will use the old upstream name instead of $new_name.

# Push the new branch to remote

# Reset the upstream branch for the new_name local branch
git push $remote -u $new_name
