Putting all that together, I'd recommend:

   PATTERN='https?://[^/]*\.in/'
   grep "$PATTERN" file.of.links > links.in

Minor nit, egrep is needed for the '?' or grep -E.

Oops, yep.  I'm usually writing perl (and occasionally using grep -P) so
I forgot.

OK, thanks everybody.

Had to use egrep. This works:

PATTERN='https?://[^/]*\.in(/.*)*'
egrep $PATTERN file.of.links > links.in

Covers cases with https and where nothing follows the .in
