cannot recover files after deleted running git rm --cached

Question

I cannot recover my accidently deleted files after running git rm --cached . I have tried to git reset hard and several other ways but nothing helps

[ec2-user@ip-10-0-0-190 cgsignlab]$ git rm --cached .
fatal: not removing '.' recursively without -r

Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'


[ec2-user@ip-10-0-0-190 cgsignlab]$ git status

Answer 1

git fsck could be helpful here:

git fsck --unreachable

This should output list of hashes (potentially much more than the list that you've deleted). Then use those hashes to obtain their content with:

git cat-file -p <hash>

Unfortunately you wouldn't get file name, only its content.
