Created January 28, 2014 20:52
Rollback a `git commit`
Undo a commit and redo
$ git commit ... (1)
$ git reset --soft 'HEAD^' (2)
$ edit (3)
$ git add .... (4)
$ git commit -c ORIG_HEAD (5)
This is what you want to undo
This is most often done when you remembered what you just committed is incomplete, or you misspelled your commit message, or both. Leaves working tree as it was before "reset". (The quotes may or may not be required in your shell)
