Tip #77   Bash fork bomb

Don't forget the bash fork bomb. DO NOT TRY THIS AT HOME... Posted here so that you don't see this in a forum or a mailing list and use it without knowing:

$ :(){ :|:& };:

defines a function called : (accepts no arguments)
{ :|:& };
This is the function: It calls the function itself and pipes the output to the same function ":" and puts the process in the background. (Recursive invocation) with ; it ends the function definition
Calls the function and creates havoc.
