sed -n 's%^.*\(\(\(\(\(ht\|f\)tp\)\|mailto\):\(//\)\?[^ >"]*\|www.[-a-z0-9.]+\)[^
.,;>">]\).*$%\1%p;t c;d;:c q'
or:
perl -ne 'if (m%((((ht|f)tp)|mailto):(//)?[^ >"]*|www.[-a-z0-9.]+)[^ .,;>">]%) {print
$&; exit}'
which is actually shorter, and easier to read ..
if you're just looking for (ht|f)tp urls, the regex becomes quite a
bit simpler
