I'm not quite sure how best to define/articulate this, but I'm looking for a way to pseudo-spider a website. The key is that I don't actually want the content, but rather a simple list of URIs. I can get reasonably close to this idea with Wget using the --spider option, but when piping that output through a grep, I can't seem to find the right magic to make it work:

wget --spider --force-html -r -l1 http://somesite.com | grep 'Saving to:'

The grep filter seems to have absolutely no affect on the wget output. Have I got something wrong or is there another tool I should try that's more geared towards providing this kind of limited result set?

Thanks.

UPDATE

So I just found out offline that, by default, wget writes to stderr. I missed that in the man pages (in fact, I still haven't found it if it's in there). Once I piped the return to stdout, I got closer to what I need:

wget --spider --force-html -r -l1 http://somesite.com 2>&1 | grep 'Saving to:'

I'd still be interested in other/better means for doing this kind of thing, if any exist.
