meta crawler?

Ok so I am doing some SEO work for a company, and there are a lot of pages that do not have meta discriptions... Their website has 1000s of pages that should all be indexed, is there a tool that can check every page and just asks this question:

Does this page have a metatitle? If no, red flag.

So I can have a list of all pages that do not have them, would be very cool and save lots and lots of time.

Yes there is a tool just open a shell and use grep.

+1 for grep
but to download whole site first.
