Retrieve deleted stash in Git using SourceTree

I am using source tree. I had created a stash of multiple changes and by mistake deleted it. Is there a way to retrieve them back?

Based on previous answers, here is a simple sequence:

Open a terminal window and cd into a folder under the repository. Then:

git fsck | awk '{print $3}' > tmp.txt
cat tmp.txt | xargs git show > tmp2.txt

Now open tmp2.txt in editor, locate your lost code, and find the commit-id on top of it. Then apply the code:

git stash apply <commit id>
rm tmp.txt tmp2.txt

This saved my life! I really thank all those who answered this question. I bless the git creator Linus Torvalds for keeping deleted stuff in the git database. Genius!!

EDIT 2021: note that Windows users can do the same using Git Bash.

The stash is saved internally as a merge commit referenced from a list of stashes.

git fsck can find dangling objects. It will find not just your deleted stash, but probably other stuff, too... so you'll be wanting to look for commits that look like they could be your stash (git show <ID> to display relevant info about an object and decide whether it's the one you're looking for).

Once you have that, all you need to do is re-insert it into the list of stashes. The list is stored in .git/logs/refs/stash and a line has the following format:

<ID of previous stash commit in list or 0000000000000000000000000000000000000000 if none> <ID of merge commit> Your Name <your@email.example> <UNIX timestamp> <time zone, e.g. +0000><TAB char><description of stash>

Here's a working example:

16b9a2d400dafe7ea25592029e3e5582d025c7d8 5def7605dfe625e8b3a3152fe52a87cc36694b6a Jan Krüger <email.censored@invalid> 1374227992 +0200	WIP on master: 0dbd812 Update draft release notes to 1.8.4

Just synthesize a line for the stash you want to re-insert (the name/mail/timestamp/description don't have to be accurate) and you should be able to use it normally again.

Happy hunting!

Like the previous answer states, you can use git fsck to list objects that aren't referenced by anything which would include your deleted stash. But, it is possible to use git show to filter that list of objects to show only stashes like:

git fsck 2> /dev/null |
  awk '/commit/{print $3}' |
  git show --stdin --merges --grep '^WIP on'

If you know when the stash was created, you could also add an argument like --since '2 days ago' to the final line to limit the output further. Hopefully that will cut the list down to a manageable size.

Once you've found the correct stash make note of its commit ID, and you can use git stash apply COMMITID to apply it as if it hadn't been deleted.

This is the most cleaner workaround to recover deleted stash.

1. git fsck --lost-found

2. ls -1 .git/lost-found/commit/ | xargs -n 1 git log -n 1 --pretty=oneline

3. git stash apply [tag]

Replace [tag] with the id, ex:

> git stash apply 40e47250d0b4fb6143be67c115b708be126e79d3

It might be helpful to use comments while stashing, using:

git stash save "comment"

It saved me some trouble finding already deleted stash using the following:

git fsck --lost-found

ls -1 .git/lost-found/commit/ | xargs -n 1 git log -n 1 --pretty=oneline

git stash apply [tag]

As Jan Krüger states above, git fsck is the way to go. However, if you find yourself unable (for whatever reason) to successfully synthesize a line in your stash file and make the stash appear in the available list, you can use git stash apply <guid> directly, without adding the line. This will immediately apply (not commit) the file(s) changes to your current branch.

Another solution is:

git fsck 2>&1 | awk '/dangling commit/{print $3 "^!"}' | xargs git log

find the author and commit informations(date,hash,author etc.)

git stash store <hash-id-of-specific-commit>

for i in $(git fsck 2>|/dev/null | grep commit | cut -d' ' -f3); do git --no-pager log -1 $i; echo "-------------------------"; done | less

Then find the commit id#.

and do

git stash apply {commit#}

There is a option in source tree to see stashes. Just right click on stash that you want to revert. Its will give you two options, 'Apply Stash' and 'Delete Stash'. Choose 'Apply Stash'.
