Find and restore a deleted file in a Git repository

问题


Say I\'m in a Git repository. I delete a file and commit that change. I continue working and make some more commits. Then, I find I need to restore that file.

I know I can checkout a file using git checkout HEAD^ foo.bar, but I don\'t really know when that file was deleted.

  1. What would be the quickest way to find the commit that deleted a given filename?
  2. What would be the easiest way to get that file back into my working copy?

I\'m hoping I don\'t have to manually browse my logs, checkout the entire project for a given SHA and then manually copy that file into my original project checkout.


回答1:


Find the last commit that affected the given path. As the file isn't in the HEAD commit, this commit must have deleted it.

git rev-list -n 1 HEAD -- <file_path>

Then checkout the version at the commit before, using the caret (^) symbol:

git checkout <deleting_commit>^ -- <file_path>

Or in one command, if $file is the file in question.

git checkout $(git rev-list -n 1 HEAD -- "$file")^ -- "$file"

If you are using zsh and have the EXTENDED_GLOB option enabled, the caret symbol won't work. You can use ~1 instead.

git checkout $(git rev-list -n 1 HEAD -- "$file")~1 -- "$file"

  1. Use git log --diff-filter=D --summary to get all the commits which have deleted files and the files deleted;
  2. Use git checkout $commit~1 path/to/file.ext to restore the deleted file.

Where $commit is the value of the commit you've found at step 1, e.g. e4cf499627

To restore all those deleted files in a folder enter the following command.

git ls-files -d | xargs git checkout --

I came to this question looking to restore a file I just deleted but I hadn't yet committed the change. Just in case you find yourself in this situation, all you need to do is the following:

git checkout HEAD -- path/to/file.ext

If you’re insane, use git-bisect. Here's what to do:

git bisect start
git bisect bad
git bisect good <some commit where you know the file existed>

Now it's time to run the automated test. The shell command '[ -e foo.bar ]' will return 0 if foo.bar exists, and 1 otherwise. The "run" command of git-bisect will use binary search to automatically find the first commit where the test fails. It starts halfway through the range given (from good to bad) and cuts it in half based on the result of the specified test.

git bisect run '[ -e foo.bar ]'

Now you're at the commit which deleted it. From here, you can jump back to the future and use git-revert to undo the change,

git bisect reset
git revert <the offending commit>

or you could go back one commit and manually inspect the damage:

git checkout HEAD^
cp foo.bar /tmp
git bisect reset
cp /tmp/foo.bar .

My new favorite alias, based on bonyiii's answer (upvoted), and my own answer about "Pass an argument to a Git alias command":

git config alias.restore '!f() { git checkout $(git rev-list -n 1 HEAD -- $1)~1 -- $(git diff --name-status $(git rev-list -n 1 HEAD -- $1)~1 | grep '^D' | cut -f 2); }; f'

I have lost a file, deleted by mistake a few commits ago?
Quick:

git restore my_deleted_file

Crisis averted.


Robert Dailey proposes in the comments the following alias:

restore-file = !git checkout $(git rev-list -n 1 HEAD -- "$1")^ -- "$1"

And jegan adds in the comments:

For setting the alias from the command line, I used this command:

git config --global alias.restore "\!git checkout \$(git rev-list -n 1 HEAD -- \"\$1\")^ -- \"\$1\"" 



回答7:


If you know the filename, this is an easy way with basic commands:

List all the commits for that file.

git log -- path/to/file

The last commit (topmost) is the one that deleted the file. So you need to restore the second to last commit.

git checkout {second to last commit} -- path/to/file



回答8:


To restore a deleted and commited file:

git reset HEAD some/path
git checkout -- some/path

It was tested on Git version 1.7.5.4.




回答9:


If you only made changes and deleted a file, but not commit it, and now you broke up with your changes

git checkout -- .

but your deleted files did not return, you simply do the following command:

git checkout <file_path>

And presto, your file is back.

I've got this solution.

  1. Get the id of the commit where the file was deleted using one of the ways below.

    • git log --grep=*word*
    • git log -Sword
    • git log | grep --context=5 *word*
    • git log --stat | grep --context=5 *word* # recommended if you hardly remember anything
  2. You should get something like:

commit bfe68bd117e1091c96d2976c99b3bcc8310bebe7 Author: Alexander Orlov Date: Thu May 12 23:44:27 2011 +0200

replaced deprecated GWT class
- gwtI18nKeySync.sh, an outdated (?, replaced by a Maven goal) I18n generation script

commit 3ea4e3af253ac6fd1691ff6bb89c964f54802302 Author: Alexander Orlov Date: Thu May 12 22:10:22 2011 +0200

3. Now using the commit id bfe68bd117e1091c96d2976c99b3bcc8310bebe7 do:

git checkout bfe68bd117e1091c96d2976c99b3bcc8310bebe7^1 yourDeletedFile.java

As the commit id references the commit where the file was already deleted you need to reference the commit just before bfe68b which you can do by appending ^1. This means: give me the commit just before bfe68b.




回答11:


git checkout /path/to/deleted.file



回答12:


git undelete path/to/file.ext

  1. Put this in your .bash_profile (or other relevant file that loads when you open a command shell):

    git config --global alias.undelete '!sh -c "git checkout $(git rev-list -n 1 HEAD -- $1)^ -- $1" -'
    
  2. Then use:

    git undelete path/to/file.ext
    

This alias first checks to find the last commit where this file existed, then does a git checkout of that file path from that last commit where this file existed. source




回答13:


In many cases, it can be useful to use coreutils (grep, sed, etc.) in conjunction with Git. I already know these tools quite well, but Git less so. If I wanted to do a search for a deleted file, I would do the following:

git log --raw | grep -B 30 $'D\t.*deleted_file.c'

When I find the revision/commit:

git checkout <rev>^ -- path/to/refound/deleted_file.c

Just like others have stated before me.

The file will now be restored to the state it had before removal. Remember to re-commit it to the working tree if you want to keep it around.




回答14:


So I had to restore a bunch of deleted files from a specific commit and I managed it with two commands:

git show <rev> --diff-filter=D --summary --name-only --no-commit-id | xargs git checkout <rev>^ -- 
git show <rev> --diff-filter=D --summary --name-only --no-commit-id | xargs git reset HEAD 

(Note the trailing space on the end of each command.)

The files had been added to the .gitignore file and then cleared with git rm, I needed to restore the files but then unstage them. I had hundreds of files to restore, typing things manually for each file as in the other examples was going to be far too slow.




回答15:


Actually, this question is directly about Git, but somebody like me works with GUI tools like WebStorm VCS other than knowing about git cli commands.

I right click on the path that contains the deleted file, then go to Git and then click on Show History.

The VCS tools show all revisions train and I can see all commits and changes of each of them.

Then I select the commits that my friend delete the PostAd.js file. now see below:

And now, I can see my desire deleted file. I just double-click on the filename and it recovers.

I know my answer is not Git commands but it is fast, reliable and easy for beginner and professional developers. Webstorm VCS tools are awesome and perfect for working with Git and doesn't need any other plugin or tools.

user@bsd:~/work/git$ rm slides.tex
user@bsd:~/work/git$ git pull 
Already up-to-date.
user@bsd:~/work/git$ ls slides.tex
ls: slides.tex: No such file or directory

Restore the deleted file:

user@bsd:~/work/git$ git checkout
D       .slides.tex.swp
D       slides.tex
user@bsd:~/work/git$ git checkout slides.tex 
user@bsd:~/work/git$ ls slides.tex
slides.tex



回答17:


I had the same question. Without knowing it, I had created a dangling commit.

List dangling commits

git fsck --lost-found

Inspect each dangling commit

git reset --hard <commit id>

My files reappeared when I moved to the dangling commit.

git status for the reason:

“HEAD detached from <commit id where it detached>”




回答18:


In our case we accidentally deleted files in a commit and some commit later we realized our mistake and wanted to get back all the files that were deleted but not those that were modified.

Based on Charles Bailey's excellent answer here is my one liner:

git co $(git rev-list -n 1 HEAD -- <file_path>)~1 -- $(git diff --name-status $(git rev-list -n 1 HEAD -- <file_path>)~1 head | grep '^D' | cut -f 2)



回答19:


If you know the commit that deleted the file(s), run this command where <SHA1_deletion> is the commit that deleted the file:

git diff --diff-filter=D --name-only <SHA1_deletion>~1 <SHA1_deletion> | xargs git checkout <SHA1_deletion>~1 --

The part before the pipe lists all the files that were deleted in the commit; they are all checkout from the previous commit to restore them.




回答20:


Find the commit that deleted your file:

git log --diff-filter=D --oneline -- path/to/file | cut -f -d ' '

Sample output:

4711174

As of Git 2.23 there is actually a restore command. It is still experimental but in order to restore something you removed in a commit (4711174 in this case) you can then type:

git restore --source=4711174^ path/to/file

Note the ^ after the commit id as we want to restore something from the commit before the one that deleted the file.

The --source argument tells the restore command where to look for the file(s) to restore and it can be any commit and even the index.

See: git-restore doc for git 2.23.0




回答21:


Simple and precise-

First of all, get a latest stable commit in which you have that file by -

git log 

Say you find $commitid 1234567..., then

git checkout <$commitid> $fileName

This will restore the file version which was in that commit.




回答22:


I know this is an old thread, but you could always git revert your commit which deleted the file. (This assumes that the deletion was the only change in the commit.)

> git log 
commit 2994bda49cd97ce49099953fc3f76f7d3c35d1d3
Author: Dave <dave@domain.com>
Date:   Thu May 9 11:11:06 2019 -0700

    deleted readme.md

And if you've continued work, and realized later that you didn't want to commit that deletion commit, you could revert it using.

> git revert 2994bd

Now git log shows:

> git log
Author: Dave <dave@domain.com>
Date:   Thu May 9 11:17:41 2019 -0700

    Revert "deleted readme"

    This reverts commit 2994bda49cd97ce49099953fc3f76f7d3c35d1d3.

And readme.md has been restored into the repository.




回答23:


$ git log --diff-filter=D --summary  | grep "delete" | sort



回答24:


I also have this problem using below code retrieve previous file to local directory

git checkout <file path with name>

below example working for me

git checkout resources/views/usaSchools.blade.php
