wget -r -l4 --spider -D thesite.com http://www.thesite.comLet's analyse the options...
-r indicates it's recursive (so "follow the links" and look for more than one page)
-l indicates the number of levels we want to recurse. If you are on the first page and you follow a link, you are at level 1. If you follow a link on that last page, you are at level 2, etc
--spider indicates not to download anything (we just want to go through the pages, that's all)
