Useful Git Commands For Removing Accidentally Pushed or Committed Files

I find myself needing to reset commits often because I committed a file I didn't want to or forgot to add something to a commit. Every once in a while, I also need to remove the file from the remote repository (but not locally) because I accidentally pushed it. I always forget the commands, so here they are for everyone's reference :)

Remove a file you already pushed to the git repository

You can use the following command to delete a file from your git repo, for example, if you accidentally pushed it up or if you just don’t want it there any anymore.

git rm --cached name_of_file
Enter fullscreen mode Exit fullscreen mode

This will not delete it locally, so it is safe on your computer if you want to keep it in there for reference without sharing on Git. To prevent it from being pushed to Git again, just add the file to your .gitignore.

Of course, if you just don’t need the file any more at all, simply delete it from your system as well.

BUT! If the file had sensitive data like passwords or secret keys, then you need to do a little bit more because the commits can still be found in the repository's history.

If the pushed file has sensitive data like passwords

As noted by Ölbaum's comment below (thanks!), the above method will not completely remove the file from the commit history.

To remove the sensitive file from your history as well, you can use an open-source tool called the BFG Repo-Cleaner or use git's git filter-branch.

BFG Repo-Cleaner apparently makes it much easier and faster to get the job done compared to filter-branch. It allows you to delete files or, alternatively, replace the passwords or keys within the file with the text ***REMOVED***. You can also remove huge files that you accidently pushed.

I haven't used BFG myself, but check out BFG Repo-Cleaner's documentation and download page to see how to use it. The instructions are pretty strait forward.

To learn about the git filter-branch, check out git's Using filter-branch article on their help site and the git filter-branch documentation.

Remove a file you accidentally committed in your last commit (but haven’t pushed yet)

I have a habit of committing everything with git add . so sometimes I accidentally add files that I actually want to have in a separate commit.

To remove certain files from a commit that hasn’t been pushed yet, first, undo the last commit with:

git reset --soft HEAD^1
Enter fullscreen mode Exit fullscreen mode

Next, run:

git rm --cached <file-name>
Enter fullscreen mode Exit fullscreen mode

to remove the file you don’t want to commit. This removes it from the commit and sets it back to an untracked file. You should be able to confirm by doing a quick git status.

Now you can commit the other files as usual by running:

git commit -m "my commit message"
Enter fullscreen mode Exit fullscreen mode

The removed file or files can then be added into a separate commit!

Good post, thank you.

It’s worth noting that the first approach doesn’t completely remove the offending file from the remote repository. Checking out a commit between the times it was added and removed, the file will still be available. It might be important depending on the reason why you wanted to remove it. Two typical cases where it won’t be enough to delete the file in a new commit:

  • very large file that should not be committed and will unnecessarily blow up the repository size;
  • sensitive file containing passwords or API tokens.

In this case, and if the file has been there for a few commits, you will probably need to use git filter-branch, which is not for the faint of heart, or the easier to use BFG Repo-Cleaner.

Thanks for pointing that out! Definitely want to be careful with sensitive data. I added a note and link to your comment in the article so everyone will see it.
