Hi All,

I have a 1.5G IIS logfile that I am parsing and pulling out any line the contains a certain date and dumping these lines into an array.

I have written the following (very basic for demo purposes) code which takes 3 minutes to parse the file and display the array contents

if ( ! open WEBLOG, "<$weblog") {
    die "$0: Cannot open weblog: $weblog\n";
}

while ( <WEBLOG> ) {
    if ( $_ =~ m/^2007-07-13/ ) {
        push @lines, "$_\n";
    }
}

print @lines;

Can someone tell me if there is a quicker way of getting these lines out of the file? I am trying to keep memory usage and disk read time as low as possible.

Maybe I am just outta luck and 3 minutes is what I will have to live with. :)
