I know that. But it was a nice discovery for me last night,
therefore I figured it would be a nice discovery for others as
well.
But it is not a cool use for Perl. It's just shell interaction, and of a widely known kind. Look up google for "toolbox philosophy".

Correction: it wasn't a cool use for you. It was, however, a
cool use for me, and possibly others who are not experts at Unix.

The point I was trying to make (see <em>phasis on Perl) is that however cool that may be from your, or anyone else's, POV including mine, it has nothing to do with Perl itself. There are tons of things that are cool for me, some of which are appliable also to perl scripts, but such that the perlishness of the latter ones plays no role whatsoever in their coolness.
Also, while none of us all was born learnt at anything, and I can appreciate your enthusiasm which reminds me of my own whenever I discover something new, this is hardly a thing for "unix experts". Indeed I'd rather rate it around the ABC of shell (not only *NIX ones!) interaction, i.e. a "@{[('very') x 5]}" elementary thing, which I suppose is the reason why it was unvoted so much.
