1. Safe approach: Revert

   git revert <sha1-commit-hash>
   

   where the hash is of the commit to revert. This creates a new commit with all the previous commit changes undone.

2. Unsafe approach: Interactive rebase

   git rebase -i <sha1-commit-hash>
   

   where the hash points to a successful commit prior to the commit to be deleted. This brings up an editor where each commit following the hash commit above is listed. Earlier commit (one closer to the hash commit) is at the top of the editor page. Change pick to drop to remove (or edit) a past commit (or edit if wishing to update a commit changes, and reword to update a commit message).

   • When editing, make changes to code and stage them, then run git rebase --continue.
   • NOTE: To edit the most recent, not-yet-pushed commit, just use git commit --amend.
