Well, at the risk of showing what little I know, I've added your suggestion and how have:

use lib qw(blib lib);
#use strict;
use warnings;
use Getopt::Long;
use Pod::Usage;
use Data::Dumper;
use Opsware::NAS::Client;
my($user,$pass,$host) = ('a', 'b', 'localhost');
my $help = 0;
my $ip = '10.226.1.52';

#my $ip = '$tc_device_ip$';
my $nas = Opsware::NAS::Client->new();
my $res = $nas->login(-user => $user, -pass => $pass, -host => $host, 
+-nosession => '0');

$res = $nas->show_deviceinfo(ip => $ip);
unless ($res->ok()) {

  printf STDERR ("*** error: %s\n", $res->error_message());

  exit(1);

}

my ($image) = map { /^SystemImage:\s*([^\n]+)/ ? $1 : () } $res->resul
+t();

print("$image\n");  # flash:c3750-advipservicesk9-mz.122-46.SE.bin

$nas->logout();

but am getting an error of: Use of uninitialized value in string at move_image.pl line 34 So, why can't I print $image, seems like a simple thing to do.

It means the regex never matched. Please provide the output of

use Data::Dumper;
print(Dumper([$res->result()]));

Here is the output: Again, thanks for the help with this.

Some release notes at Cisco state that the line: my($user,$pass,$host) = ('a', 'b', 'localhost'); should be: my( $user, $pass, $host) = ('a', 'b', 'localhost');
