Perl » System Functions » Getopt

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";

}
