Undo a commit and redo

$ git commit ...
$ git reset --soft HEAD^      (1)
$ edit                        (2)
$ git commit -a -c ORIG_HEAD  (3)
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".

Make corrections to working tree files.

"reset" copies the old head to .git/ORIG_HEAD; redo the commit by starting with its log message. If you do not need to edit the message further, you can give -C option instead.

I actually could have used this earlier today. Starred, and thanks for posting Tim. :)

Glad helping myself helped you :)

Very useful. And this gist has been around a good while. Thanks! I didn't know about ORIG_HEAD.

Since I do this so often, I have found the following useful to add to my ~/.gitconfig:

[alias]
undo = reset --soft HEAD^
recommit = commit -a -c ORIG_HEAD

What if you revert a particular commit, then later want to re-commit the same changes?

e.g.:
commit 1
commit 2
commit 3
commit 4

commit 3 has some unfinished changes, but everything else needs pushed upstream. You can git revert 3 as long as that commit has nothing to do the the files you want to push. But the changes are in progress, and I don't want to permanently lose my place. Is there a way to get those particular changes back?

This was super useful but beware that if you had files unstaged during the original commit they will be committed with the commit -a.
