tales told of a curious soul who couldn't let it rest. It ate at his sole for days, and finally tried it. To his surprise and horror it actually worked! The command to beat all commands. The most omni-dreaded and prolific commands that anyone can do, even a guest on your computer.
I'm talking about the fabled
OS DELETION COMMAND a command whose integral evilness was discovered when some poor fool tried to delete the whole contents of his folder with the above instead of 'rm *' and deleted his root folder, and therefore everything on his computer!
It's folklore now, but tell you the story is true! Some will say that you have to use 'rm -rf /' to do it, but they both work.
