If you're interviewing a new hire, see how long it takes 'em to work out
what this does:
:; </etc/motd> /dev/tty sed 1q ;: echo "Hello, world"
Tested on all shells at my disposal; might even work on V7. Did I mention
that I use Perl, and used to use APL\360? The only reason I don't write
obfuscated code is that I might be the one who has to maintain it later...
