How to undo 'git reset'?

Question

What's the simplest way to undo:

git reset HEAD~

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

Answer 1

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.

Answer 2

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}

{N} represents the number of operations in reflog, as Mark pointed out in the comments.

Answer 3

1. Use git reflog to get all references update.

2. git reset <id_of_commit_to_which_you_want_restore>

Answer 4

Answer works most time

git reset 'HEAD@{1}'

Answer works every time

git reset --hard 'HEAD@{1}'

where --hard makes everything keeps the same as before.
