I am writing a script that will parse different types of log files and I want to have a template for the different log files...So I thought the main program would open a log file, I would then call each template and it would make a copy of the filehandle (instead of a new open) and then read the header and determine if it was for that template to handle... 
use strict; use warnings;

sub GetLogHeader
{
    open(TEMPLOG, "<&LOG");
    while (my $row = <TEMPLOG>)
    {
        print "$row\n"; last;
    }
    close(TEMPLOG);
}

my $abc;
open(LOG, "c:\\log.log") || die;

$abc = <LOG>;
my $header = GetLogHeader(\*LOG);
$abc = <LOG>;
$abc = <LOG>;

Basically I can't figure out how to pass a filehandle and then copy it. I expect that the copy can move the filepointer w/o affecting the original filehandle, but I can't really figure that out either...In this test, it seems that LOG and TEMPLOG are equal and I really want them to be able to point to different parts of the log file... I am just getting back in to Perl and am quite rusty ;-)
