A double dash (--) by itself signals the end of the command-line switches.

      

#The Getopt modules will stop looking for switches once a double dash is detected. 
#You can pass data after the double dash. 


#!/usr/bin/perl -w

use Getopt::Long;

Getopt::Long::GetOptions('print_header!'   => \$print_header);

if ( defined( $print_header ) ) {
    print "print_header flag set to $print_header\n";
}
