TL;DR;
# Checkout the branch you wanna rename
git checkout <old_branch_name>
# Rename the branch
git branch -m <new_branch_name>(Optional) Create a git alias
Either by running
git config --global alias.rename "branch -m --"or by editing your ~/.gitconfig
[alias]
rename = branch -m --Then you can just use:
git rename <new_branch_name>
Here's all the git aliases I use, if you were curious
