How can I delete all unversioned/ignored files/folders in my working copy?

Question

If I have a working copy of a Subversion repository, is there a way to delete all unversioned or ignored files in that working copy with a single command or tool? Essential

Answer 1

This oneliner works for me (based on Richard Hansen's answer, which surprisingly didn't work for files containing spaces):

svn status --no-ignore | grep '^[I?]' | cut -c 9- | xargs -d"\n" -I{} rm {}
