Let me add that this will not _really_ accelerate the process, it may give you instant gratification where you'll see a bunch of space, but by issuing a sync you're actually going to slow down the removal of files in the long run. Basically for speed you don't want to issue a sync until the rm command completes, if at all since the sync will also muck with other disk activity. -- -Alfred Perlstein [alfred@freebsd.org] Ok, who wrote this damn function called '??'?
