Re: [Bug-wget] How to set -l to be zero? (Or how to download a single webpage and convert the absolute links to relative links with wget?)

Ah, sorry, I misunderstood what you wanted. What I described will
convert relative links to absolute links, not vice versa.

You're right, to get what you want, then you need recursion; wget only
converts links to point at pages locally, if it directly knows they've
been downloaded (because it had done so). That being the case, -l 0
wouldn't have worked even if it did what you hoped, because it would not
have downloaded them, so there's no way to do it without recursing to
the links that you want to be converted afterward.
