That should work just fine, though you don't need the "g" (for "globally" at the
end) and you could just do /#// instead of replacing the # with a space. Are you
sure there's just one space char (not multiple or tab) between the # and "ftp"
and that the "#" is at the start of the line? What output do you get?
