  Thanks, I've never investigated ":" beyond noting it's presence in fork bombs. : Null command. No effect; the command does nothing. Exit Status: Always succeeds.

    Basically a builtin for `true`. Its use in forkbombs is unrelated except for the fact that it's a valid character in a bash function name. Defining `:(){:|:&)` obviously shadows the builtin.
