git tips: undo & clean

Commonly used Git commands that are worth remembering (or having a quick reference like this one for):

1. Undo your last commit: git reset HEAD~¹ (Stack Overflow)
2. Undo your last commit, but leave changes staged: git reset --soft HEAD~
3. Undo your last commit, but leave it in history: git revert HEAD~
4. Undo all current changes and reset the environment to the last commit: git reset --hard HEAD
5. Remove all untracked files: git clean -f²
6. Remove untracked directories, too: git clean -f -d
