I have tried
export $MY_VARIABLE
and then reading $MY_VARIABLE in perl program. I didnt get any value!
I tried as command line argument, however since I already have one file as input paramenter, it is interpreting another also as file input and I get a message that $MY_VARIABLE file does not exists.
Can you please show me syntax of passing file as one parameter and value as another parameter? or any other way?

NAME
CPANPLUS::Shell
SYNOPSIS
use CPANPLUS::Shell; # load the shell indicated by your

# CPANPLUS::Shell::Default
use CPANPLUS::Shell qw[Classic] # load CPANPLUS::Shell::Classic;
my $ui = CPANPLUS::Shell->new();

DESCRIPTION
This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"

Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
loading class), so please consult the documentation of your shell of choice.
