One liner to get all the domain names linked from a particular page
for domain in $(lynx --source www.stallman.org | perl -ne 'if (/href="([^"]*)"/) { print "$1\n"; }' | grep http | grep "://" ); do echo $domain | sed -e "s/[^/]*\/\/\([^@]*@\)\?\([^:/]*\).*/\2/"; done | sort -u
Also, wow… Stallman links to a ton of stuff.
