I guess the assumption here is that the script is executing with higher privs than the user supplying the arguments? If that's the case, then that's what I was missing. Otherwise, there's nothing to stop the user from just typing "rm -rf /".

In any case, thank you kindly for the explanation. Much appreciated.
