Hi there, First of all thank you very much. I am starting with perl and I trying to automate my shell scripts by perl scripts. Here my final script ( of course I will follow HAUKEX advice which is what I want. 

#!/usr/local/bin/perl
use strict;
use warnings;

my @get_vmlist = ( `xl list` );

sub show_vmlist {
        print @get_vmlist;
}


my $arg =  shift @ARGV;
my $vm_run = pop @ARGV;

sub get_vncport {
        my $DOMID = qq(DOM_ID="`xl list | fgrep $vm_run | awk '{print 
+\$2}'`" && VNCPORT="`ps x | fgrep -m 1 "domid \$DOM_ID" | awk '{print
+ \$1}'`" && sockstat -4l | fgrep \$VNCPORT | awk '{print \$6}');
        print `$DOMID`;
}

my %rec_args = ( vmlist => \&show_vmlist,
        getvnc => \&get_vncport,
);

if (defined $arg && exists $rec_args{$arg}) {
        $rec_args{$arg}->();
}
