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 included in the .gitignore file
git add .
