How to undo 'git reset'?

问题:

What\'s the simplest way to undo the

git reset HEAD~

command? Currently, the only way I can think of is doing a \"git clone http://...\" from a remote repo.

Short answer:

git reset \'HEAD@{1}\'

Long answer:

Git keeps a log of all ref updates (e.g., checkout, reset, commit, merge). You can view it by typing:

git reflog

Somewhere in this list is the commit that you lost. Let\'s say you just typed git reset HEAD~ and want to undo it. My reflog looks like this:

$ git reflog
3f6db14 HEAD@{0}: HEAD~: updating HEAD
d27924e HEAD@{1}: checkout: moving from d27924e0fe16776f0d0f1ee2933a0334a4787b4c
[...]

The first line says that HEAD 0 positions ago (in other words, the current position) is 3f6db14; it was obtained by resetting to HEAD~. The second line says that HEAD 1 position ago (in other words, the state before the reset) is d27924e. It was obtained by checking out a particular commit (though that\'s not important right now). So, to undo the reset, run git reset HEAD@{1} (or git reset d27924e).

If, on the other hand, you\'ve run some other commands since then that update HEAD, the commit you want won\'t be at the top of the list, and you\'ll need to search through the reflog.

One final note: It may be easier to look at the reflog for the specific branch you want to un-reset, say master, rather than HEAD:

$ git reflog show master
c24138b master@{0}: merge origin/master: Fast-forward
90a2bf9 master@{1}: merge origin/master: Fast-forward
[...]

This should have less noise it in than the general HEAD reflog.

回答2:

Old question, and the posted answers work great. I\'ll chime in with another option though.

git reset ORIG_HEAD

ORIG_HEAD references the commit that HEAD previously referenced.

回答3:

My situation was slightly different, I did git reset HEAD~ three times.

To undo it I had to do

git reset HEAD@{3}

so you should be able to do

git reset HEAD@{N}

But if you have done git reset using

git reset HEAD~3

you will need to do

git reset HEAD@{1}

As {N} represents number of operations in Reflog. As Mark pointed out in the comments.

1.Use git reflog to get all references update.

2.git reset <id_of_commit_to_which_you_want_restore>
