Linux commands that will totally fuck you up

:(){ :|:& };:

The > redirects raw output, and in this case, to your hard disk, effectively corrupting and destroying the filesystem. 'ls' is used here, but any command can be used.


ls > /dev/sda

Probably the simplest way to hose your system. It recursively deletes all files from the root of your filesystem.


rm -fr /

Grants read, write, and execute rights to every file for every user.

mkfs /dev/sda

dd if=/dev/zero of=/dev/sda
