Intro

You might want to remove some files commited to source control. This is the case with:

  • Secrets accidentally checked into SCM.
  • Large binary files which make the size of the repo too large.

Git considerations

Removing the file from the repo and creating a new commit will remove the file from the file system, but the file remains in the Git history.

Entirely removing a file requires you to rewrite the repo’s history since the time that file was written into it.


git filter-branch --index-filter "git rm --cached --ignore-unmatch 'path/largevideo.mp4'"

You have now removed the file from your local history.

If you git pull now, you will get the file again, as it still lives in the Git history in the server. We now need to remove the file from the server’s Git history:

git push --force

Other team members must now pull from the server, as their local history is now different and they won’t be able to push.
