Thanks, Courage :)

Did you mean the following?

use Benchmark; $start = new Benchmark; open(FH, "wrongs") or die $!; open(FH2, ">wrongs2") or die $!; undef $/; $lines = <FH>; $counted2 = $lines =~ s/wrongs/wrongs4/g; print FH2 "$lines"; $/ = "\n"; close (FH); close (FH2); $end = new Benchmark; # calculate difference $diff = timediff($end, $start); print "replaced: $counted2 The operation took: " , timestr($diff, 'all +');

    yes, you're fast to learn. :)
    regular expressions were speed-optimized a lot. Do RTFS a bit, and you'll have an idea on what I have in mind.

    A drawback of such optimization - no-one now can improve that code, because it is highly complicated.

    Well, this is not the only place on where perl has good speed abilities.

    Best regards,
    Courage, the Cowardly Dog

      Ilya has that general effect. :-)
