      1. git commit --amend (please use vim as default in terminal)
      2. git push -f
   2. if you just want to modify the last \(N^{th}\) comment that you just committed.
      1. git rebase -i HEAD~N first you go back
      2. modify the comment and replace pick with edit in corresponding line
      3. git commit --amend do it again
      4. git rebase --continue you can come back now
      5. git push -f
   3. if you have local modification, try git stash (to archive modifications) and git stash pop (restore)
