using system function we can achieve this.
See the following example code. 
use strict;
use warnings;
use Getopt::Std;
.
.
.
my %option=();
getopts("hwmyc:",\%option);
.
.
.
if(defined $option{h})
{
   system("less help_file");
   #system("cat help_file | less");
   #system("echo "this is help file"|less");
}
.
.
