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 is similar to other answers, but actually gets ignored files (note the 'I' in the REs):

 rm -rf `svn status --no-ignore | grep '^[\?I]' | sed 's/^[\?I]//'`
