Did not see this on the cheat sheet, but is this right for filtering (out) numbers only?

^[0-9]+$

And this would be to filter out any jpg prefixed with numbers:


^[0-9]+$\.jpg

Yes?

The ^ for "not" doesn't work. You can put

[0-9]+\.jpg

in the reject field, that will work.

I was about to say, but surely the addresses are both exactly the same...

But then I noticed that Smite had edited his entry! D'oh.

While we're at it, there's a complete regex tutorial at regular-expressions.info.

I have used RegEx Coach when I am doing Perl development, I like the way it will walk you thru stuff.

A waaaay late entry to the party.
You can also use \d instead of [0-9]. Saves a couple characters.

Seems like a good place to share this. I don't use Regex enough to become very proficient, let alone master it. Recently I came across the free (with registration) tool below and I've used it a few times to test RE's that I use with NB. Took a tiny bit of time getting the hang of it and I hardly use its full potential, but It's real handy.
