Git: deleted a bunch of files accidentally, how to get them back?

You know the the sinking feeling when you accidentally wiped out half of the repo with a harmless looking rm -rf. No worried though, there’s a high change of getting it all back if it’s a Git repo.

Deleted – nothing else after that

Just deletion, and no staging or nothing after that. Checkout should do the trick:

$ git checkout .

Deleted – added to the staging area

File got deleted and then added to the staging area, at this point you noticed that something’s wrong:

# Reset the head first
$ git reset HEAD <file>

# Then checkout
$ git checkout <file>

# Or if it’s a ton of files, then use the dot
$ git reset HEAD .
$ git checkout .

Deleted — added, and committed

If you went the whole way and committed all the deletions, then rollback with reset to the last commit. The following will roll back 1 commit:

$ git reset --hard HEAD~1

Or rollback to s specific commit ID:

$ git reset --hard 80789fa6a027b3ee3dec760e5784c61b7e4c9d17

Get the commit ID with git log.

Takeaways

It’s relatively hard to delete anything permanently in Git.
