wget directory listing

wget --spider -r --no-parent https://www.example.com/

--spider
   When invoked with this option, Wget will behave as a Web spider, which means that it will not download the pages, just check that they are there. For example, you can use Wget to check your bookmarks:
   i.e.
   wget --spider --force-html -i bookmarks.html
   note - This feature needs much more work for Wget to get close to the functionality of real web spiders.
