Removing empty directories

Sometimes you need to recurse through a directory tree and remove empty directories. A typical example of doing this is when you you're managing a news server and have removed some newsgroups.

This snippet of perl on the command line should do the trick:

perl -MFile::Find -e 'find( { wanted => sub {}, postprocess => sub { rmdir $File::Find::name } }, @ARGV )'
