    How to change your commit messages in Git?

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 🙂.
Not pushed + most recent commit:

git commit --amend
This will open your $EDITOR and let you change the message. Continue with your usual git push origin master.

                How is git commit sha1 formed
              
          
    Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺
Locally, I'm at this commit:

commit d6cd1e2bd19e03a81132a23b2025920577f84e37
Author: jnthn <jnthn@jnthn.net>

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.
