Well, a cat might decide to go to sleep in the middle, or take a nap
perhaps, or, um, I don't know, maybe chase a ball of string. Or go
eat something.
Kidding!!
What I meant was that I never tried either cp or cat in place of dd
for the manner suggested above. They might work--but then again,
they may not. dd has one certain benefit I can think of, which is
telling you how many blocks it managed to write (or read), so you
can do a poor-man's-resume if necessary (use the skip= option).
After all, even on a LAN, re-transferring 4 GB just because the
network was down during the last 10k is a bummer.
