git-amend
Parameter of git-commit command that adds the current staging area to the last commit and allows you to (by default) edit previously used commit message or (if other options were given) reuse it or even discard it and write a new one.

New commit!

Using this option effectively creates new commit! It replaces current tip of the branch, so if you use it on anything that's NOT the tip (checking out a tag or SHA and then amending) you're effectively branching (feel free to check with logs).

It's considered a rough equivalent of

  • soft reset,
  • manual changes
  • and committing on top of ORIG_HEAD.

Trivia

  1. You may also use it to amend a merge commit.
  2. Using --reset-author with --amend you also reset author and author timestamp.
