Answer by Can Tecim for How do I recover a dropped stash in Git?

In OSX with git v2.6.4, I just run git stash drop accidentally, then I found it by going trough below steps

If you know name of the stash then use:

$ git fsck --unreachable | grep commit | cut -c 20- | xargs git show | grep -B 6 -A 2 <name of the stash>

otherwise you will find ID from the result by manually with:

$ git fsck --unreachable | grep commit | cut -c 20- | xargs git show

Then when you find the commit-id just hit the git stash apply {commit-id}

Hope this helps someone quickly
