I first found this story in a collection of Unix horror stories several years ago: <a href="http:&#x2F;&#x2F;www.yak.net&#x2F;carmen&#x2F;unix_horror_stories" rel="nofollow">http:&#x2F;&#x2F;www.yak.net&#x2F;carmen&#x2F;unix_horror_stories</a><p>If you enjoyed this one, you&#x27;ll probably enjoy the others in there as well.
