I am trying to automate an installation of a backup client, the challenge I am facing is the below question will be asked during installation 2 times. "Enter pack name" The first time I need to pass a value "NB_CLT_7.6.0.2" and next time I need to pass a value "q". Every time when I run the script, it is passing a value "NB_CLT_7.6.0.2" both the times and the installation never ends. The below is my code and how to make sure I pass 2 values for the same questions. 

use strict;
use File::Copy;
use Expect;

my $timeout = '320';
my $current = qx{pwd};
my $NB = 'NetBackup_7.6.0.1_CLIENTS2.tar.gz';
my $patch = 'NB_CLT_7.6.0.2_Patch.tar';
        my $patchtar = `/bin/tar -xf $patch`;
        chdir("/app");
        my $exp = Expect->spawn("./NB_update.install -s");
        $exp->expect($timeout,
        [ qr/Enter pack name \(or q\) \[q\]:\s+/ => sub {
                $exp->send("NB_CLT_7.6.0.2\r");
                exp_continue;
                }
        ],
        [ qr/Do you want to kill all NetBackup daemons\? \[y,n\] \(y\)
+\s+/ => sub {
        $exp->send("\r");
                        exp_continue;
        }
        ],
        [ qr/Do you want to continue the install\? \[y,n\] \(n\)\s+/ =
+> sub {
                        $exp->send("y\r");
                        exp_continue;
                       }
        ],
        [ qr/Enter pack name \(or q\) \[q\]: \(q\)\\s+/ => sub {
                        $exp->send("\r");
                        exp_continue;
                        }
        ],
        [ qr/Do you want to restart all NetBackup daemons\? \[y,n\] \(
+y\)\s+/ => sub {
                        $exp->send("\r");
                        exp_continue;
                        }
               ],
        );
        $exp->soft_close();

        chdir("../");
