    The latter would use less memory, and start printing the first line sooner.

    # but have you tried this?
foreach (sort <FILE>) { print; }

      Personally, I'd do:
        print while <FH>;

      or even: print do { local($/), <FH> }; But think, for a moment, about: 
        while (sort <FH>) {
    print;
  }

      You're now calling sort() in scalar context. It returns false, so that while() loop doesn't do jack. And I HIGHLY recommend against 
        for (<FH>) {
    print;
  }

      Since that builds up a list of all the records in FH. -- japhy on EFnet, japh on DALnet, Jeff on Earth
