This thread is one of the best I've seen on HN. 1001 ways to screw yourself in bash. Love it. My contribution is a message from Mr. Odus himself- also a Reverend.

Don't do this unless you want a bad day: :)

  `printf "\ fr- mr odus"|rev`

Sorry, but

  sudo rm -rf \

...doesn't do anything.

rev(1) doesn't reverse your slashes. :D
