How to undo the most recent commits in Git?

I accidentally commit -ed wrong files to Git, but I haven't push -ed the commit to the server yet.

How can I undo those commits from the local repository?


Undo a commit and redo

$ git commit -m "Something terribly misguided"              (1)
$ git reset HEAD~                                           (2)
<< edit files as necessary >>                               (3)
$ git add ...                                               (4)
$ git commit -c ORIG_HEAD                                   (5)
  • This is what you want to undo
  • This leaves your working tree (the state of your files on disk) unchanged but undoes the commit and leaves the changes you committed unstaged (so they'll appear as "Changes not staged for commit" in git status , and you'll need to add them again before committing). If you only want to add more changes to the previous commit, or change the commit message1, you could use git reset --soft HEAD~ instead, which is like git reset HEAD~ (where HEAD~ is the same as HEAD~1 ) but leaves your existing changes staged.
  • Make corrections to working tree files.
  • git add anything that you want to include in your new commit.
  • Commit the changes, reusing the old commit message. reset copied the old head to .git/ORIG_HEAD ; commit with -c ORIG_HEAD will open an editor, which initially contains the log message from the old commit and allows you to edit it. If you do not need to edit the message, you could use the -C option.

  • 1 Note, however, that you don't need to reset to an earlier commit if you just made a mistake in your commit message. The easier option is to git reset (to upstage any changes you've made since) and then git commit --amend , which will open your default commit message editor pre-populated with the last commit message.

    Beware however that if you have added any new changes to the index, using commit --amend will add them to your previous commit.

    If pushed,

    git push origin master --force
    

    Undoing a commit is a little scary if you don't know how it works. But it's actually amazingly easy if you do understand.

    Say you have this, where C is your HEAD and (F) is the state of your files.

       (F)
    A-B-C
        ↑
      master
    

    You want to nuke commit C and never see it again . You do this:

    git reset --hard HEAD~1
    

    The result is:

     (F)
    A-B
      ↑
    master
    

    Now B is the HEAD. Because you used --hard , your files are reset to their state at commit B.

    Ah, but suppose commit C wasn't a disaster, but just a bit off. You want to undo the commit but keep your changes for a bit of editing before you do a better commit. Starting again from here, with C as your HEAD:

       (F)
    A-B-C
        ↑
      master
    

    You can do this, leaving off the --hard :

    git reset HEAD~1
    

    In this case the result is:

       (F)
    A-B-C
      ↑
    master
    

    In both cases, HEAD is just a pointer to the latest commit. When you do a git reset HEAD~1 , you tell Git to move the HEAD pointer back one commit. But (unless you use --hard ) you leave your files as they were. So now git status shows the changes you had checked into C. You haven't lost a thing!

    For the lightest touch, you can even undo your commit but leave your files and your index :

    git reset --soft HEAD~1
    

    This not only leaves your files alone, it even leaves your index alone. When you do git status , you'll see that the same files are in the index as before. In fact, right after this command, you could do git commit and you'd be redoing the same commit you just had.

    One more thing: Suppose you destroy a commit as in the first example, but then discover you needed it after all ? Tough luck, right?

    Nope, there's still a way to get it back. Type git reflog and you'll see a list of (partial) commit shas that you've moved around in. Find the commit you destroyed, and do this:

    git checkout -b someNewBranchName shaYouDestroyed
    

    You've now resurrected that commit. Commits don't actually get destroyed in Git for some 90 days, so you can usually go back and rescue one you didn't mean to get rid of.


    This took me a while to figure out, so maybe this will help someone...

    There are two ways to "undo" your last commit, depending on whether or not you have already made your commit public (pushed to your remote repository):

    How to undo a local commit

    Let's say I committed locally, but now want to remove that commit.

    git log
        commit 101: bad commit    # latest commit, this would be called 'HEAD'
        commit 100: good commit   # second to last commit, this is the one we want
    

    To restore everything back to the way it was prior to the last commit, we need to reset to the commit before HEAD :

    git reset --soft HEAD^     # use --soft if you want to keep your changes
    git reset --hard HEAD^     # use --hard if you don't care about keeping the changes you made
    

    Now git log will show that our last commit has been removed.

    How to undo a public commit

    If you have already made your commits public, you will want to create a new commit which will "revert" the changes you made in your previous commit (current HEAD).

    git revert HEAD
    

    Your changes will now be reverted and ready for you to commit:

    git commit -m 'restoring the file I removed by accident'
    git log
        commit 102: restoring the file I removed by accident
        commit 101: removing a file we don't need
        commit 100: adding a file that we need
