I am having a problem with understanding expect. I have am trying to create an shh script. I have 3 different conditions:

1. host is unknown it needs to be added to known host list,
2. host needs password,
3. host dose not need password as it is using ssh key.

 $exp->expect($timeout,
             [ qr/\(yes\/no\)\?/i, sub { my $self = shift;
                                      $self->send("yes\r");   <----unk
+nown host
                                      exp_continue; }],
             [ qr/password: /i, sub { my $self = shift;
                                      $self->send("$password\n"); <---
+--- needs password
                                      exp_continue; }],
             [ qr/#/i, sub { my $self = shift;                 <------
+-- ready to go.
                                      $self->send("ls\n");
                                      ;
                                       }],

            );

So how do I, once I get through the 3 conditions continue using expect?

$exp->expect($timeout,
             [ qr/#/i, sub { my $self = shift;
                                      $self->send("ll\n");  <---- only
+ works when I have a line below (crazy that is how I know this is not
+ right)
                                      ;
                                       }],                          un
+less ($exp->expect($timeout, -re , "~")){} ;

            );

What I would like is to get past the three different ssh scenarios and keep going on.

#!/usr/bin/env perl
use strict;
use warnings;
use Expect;
#$Expect::Exp_Internal = 1;
my $command = "ssh";
my $user = "root";

my @ips = ("10.16.135.157");
my $cnt= 0+@ips;
my $password = "aristo1";
my $timeout = 10;
for (my $i =0; $i < $cnt; $i++) {
my $exp = Expect->spawn ($command, "$user"."@"."$ips[$i]");
#$exp->debug(2);

$exp->expect($timeout,
             [ qr/\(yes\/no\)\?/i, sub { my $self = shift;
                                      $self->send("yes\r");
                                      exp_continue; }],
             [ qr/password: /i, sub { my $self = shift;
                                      $self->send("$password\n");
                                      exp_continue; }],
             [ qr/#/i, sub { my $self = shift;
                                      $self->send("ls\n");
                                      ;
                                       }],

            );

$exp->expect($timeout,
             [ qr/#/i, sub { my $self = shift;
                                      $self->send("ll\n");
                                      ;
                                       }],

            );


unless ($exp->expect($timeout, -re , "~")){} ;
#                 $exp->send("time\n");
