Excellent! Thank you. I knew it was something easy, just hadn't kick-started my brain yet this morning. But I've got another one. What if the user input, say, '007' on the command line? How can I strip that off? I think I can check for it with something like this:
/^0?[1-9]/
But If I find it, how do I strip it off?
--As for the rest, it is mine.
Don't bother. ;)
It's a number, after all. Perl will remove leading zeros for you, as long as there are only numbers. Strip out anything that isn't valid, and add the zero when you need it. (I suggest sprintf, personally.)
