You misunderstood the other replies.  It's not the job of a Unix
utility to prevent system administrators (who should, after all,
know better -- and who could, easily enough, RTFM if they didn't)
from hosing their systems with invalid input.

Unix utilities don't try to guess what you _really_ meant to type
on the command line; that's your job.  Unix gives you enough rope;
tie knots or hang yourself, but the rope's all there.
