Amend the HEAD commit

1. Make code changes and stage them (git add <files>)

2. Run:

$ git commit --amend

3. The previous step will open up the commit message in git's configured text editor. If you want - make changes to the commit message - then save and close the editor.

4. To verify that everything looks fine, run:

$ git show HEAD

This will show the diff of the commit you just amended and should now include the changes you staged in (1)

5. You're done!

Amend a commit behind HEAD

1. Run:

$ git rebase --interactive HEAD~X

Where X is the number of commits from HEAD where the commit you wish to amend is.

2. Git will now open its configured text editor and list all the commits from HEAD to your commit. Change pick to edit for the commit you want to edit. Save and close the editor.

3. Make your changes.

4. Commit your changes:

$ git commit --all --amend --no-edit

Where --all stages unstaged changes, --amend edits the commit and --no-edit leaves the commit message unchanged.

5. Complete the rebase:

$ git rebase --continue

6. You're done!
