Edit an earlier commit

If you want to edit a commit in the history without doing a reset and having to redo the commits after. The approach here is to do an interactive rebase.

1. Start interactive rebase

    git rebase -i HEAD~3
   

2. Select commit to edit. In the text editor, change pick to edit for the target commit, then save and close.
3. Apply changes. Modify your files as needed and stage them.

    git add <file-name>
   

4. Amend the commit

    git commit --amend --no-edit
   

5. Complete rebase

    git rebase --continue
