RANDOM thought

I do so much with Perl one-liners, I sometimes miss out on what my shell can do. I just learned about $RANDOM this morning! If I had needed to Generate a MAC address, I think I would have written

    perl -E 'say join ":", map {sprintf "%02X", rand 256} 1..6'

and never investigated what bash can do.

Meh, the perl code is cleaner, shorter, and easier to read, but I do concur that $RANDOM is a nifty utility (that I also did not know about).
