Recover files after bad git reset --hard command

This one is going to take an expert:

I ran a

git init
git add --all
and a new project I worked on for way too long before I realized I hadn't setup the git repot. After running the git add I realized I forgot to create an .gitignore file. Without thinking I ran
git reset --hard HEAD
and OH NO all my files are gone, there's no log or reflog, no status and all commands result in
fatal: bad default revision 'HEAD'
. I'm sure the answer is that I'm screwed. Can't seem to do anything with any of the dangling blobs, etc. Hoping some guru out there knows something I don't.

git fsck --full git:master
notice: HEAD points to an unborn branch (master)
Checking object directories: 100% (256/256), done.
notice: No default references

You can still recover the content!

To be safe, first, do:

git fsck --lost-found

This will save the blobs to .git/lost-found/other

With the output of git fsck, you can now commands like

git show c57eff55ebc0c54973903af5f72bac72762cf4f4 > filename

to recover the files. This easily recovers the content, but not the filenames.

You can do this for all the blobs with a simple command like:

for blob in $(git fsck --lost-found | awk '$2 == "blob" { print $3 }'); do git cat-file -p $blob > $blob.txt; done
