At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.
git commit --amendThis will open your $EDITOR and let you change the message. Continue with your usual git push origin master.
