git-instafix

git instafix is a tool that allows you to easily amend (or fix) previous Git commits.

How it works:

  • Commit your original changes.
  • Make more changes and stage them with git add -p.
  • Run git-instafix (or git instafix, but this doesn't tab complete for me).
  • Select the commit you want to amend.
  • git-instafix will amend it and move you back to the HEAD commit.
