For sed, ^.* is greedy and consumes all but the last digit, and + needs to be \+ or else use the posix \([0-9][0-9]*\).... and in any case 's/[^0-9]*//g' works just as well, ... Thanks for the tr -c` example, but isn't that trailing \012 surperfluous?

@Peter Thanks for catching that. I'd have sworn I tested the sed example. :( I've changed it to your version. Regarding \012: it is needed otherwise tr will eat the newlines.

Aha... I was seeing it as \0, 1, 2 (or even \, 0, 1, 2). I'm not well enough attuned to octal it seems.. Thanks.
