Is there a way to remove all ignored files from a local git working tree?

Yesterday I spent several hours debugging a problem with my git repo that wasn't fixed by git reset HEAD --hard because the files causing the problem were ignored by .gitignore. Is there a way to "flush" or "clean" a git repo of all files that are being ignored, so that only the files tracked by git are present?

I finally fixed my problem by deleting the repo and cloning it from github again, but in the future, I would like to immediately remove all potentially problematic files (those that are being ignored).

git clean -dfX

git-clean - Remove untracked files from the working tree
-d for removing directories
-f remove forcefully
-n Don’t actually remove anything, just show what would be done.
-X Remove only files ignored by Git. This may be useful to rebuild everything from scratch, but keep manually created files.

If the ignored files are already added to the index/staging, you must remove the files from the tracking index before using the above clean command.

git rm -rf --cached .

Then add the files except the ones mentioned in the .gitignore file

git add .

There is a single command solution:

git ls-files --ignored --exclude-standard | sed 's/.*/"&"/' | xargs git rm -r --cached

What it does is:

• List all ignored files
• Handle paths with spaces to avoid failure
• Call git rm -r --cached to remove all the ignored files from index (without removing them from your local machine)
