Git undo local branch delete

Question

I just deleted the wrong branch with some experimental changes I need with git branch -D branchName.

How do I recover the branch?

Answer 1

This worked for me:

git fsck --full --no-reflogs --unreachable --lost-found
git show d6e883ff45be514397dcb641c5a914f40b938c86
git branch helpme 15e521b0f716269718bb4e4edc81442a6c11c139

Answer 2

If you know the last SHA1 of the branch, you can try

git branch branchName <SHA1>

You can find the SHA1 using git reflog, described in the solution here.

Answer 3

If you haven't push the deletion yet, you can simply do :

$ git checkout deletedBranchName

Answer 4

You can use git reflog to find the SHA1 of the last commit of the branch. From that point, you can recreate a branch using

git branch branchName <sha1>

Edit: As @seagullJS says, the branch -D command tells you the sha1, so if you haven't closed the terminal yet it becomes real easy. For example this deletes and then immediately restores a branch named master2:

user@MY-PC /C/MyRepo (master)
$ git branch -D master2
Deleted branch master2 (was 130d7ba).    <-- This is the SHA1 we need to restore it!

user@MY-PC /C/MyRepo (master)
$ git branch master2 130d7ba

Answer 5

First: back up your entire directory, including the .git directory.

Second: You can use git fsck --lost-found to obtain the ID of the lost commits.

Third: rebase or merge onto the lost commit.

Fourth: Always think twice before using -D or --force with git :)

You could also read this good discussion of how to recover from this kind of error.

EDIT: By the way, don't run git gc (or allow it to run by itself - i.e. don't run git fetch or anything similar) or you may lose your commits for ever.

Answer 6

Thanks, this worked.

git branch new_branch_name sha1

git checkout new_branch_name

//can see my old checked in files in my old branch
