A simple example of Net::SSH::Expect..this simply connects
through ssh then check the prompt then sends a command or input.. 
my $ssh= Net::SSH::Expect->new( host => $host,
                                password=> $password,
                                user => $user,
                                raw_pty =>1,
                                log_file => $outputfile."\.raw"
                                );
$ssh->login();
$ssh->send("sudo su");
if ($ssh->peek(1)=~/Password\:/ig){######check if Password prompt come
+s up###
        $ssh->send("supassword");
}
my $commandline=$ssh->eat($ssh->peek(1));
$commandline=~ s/Password\://g; #####remove string "Password:"     
$commandline=~ s/su|sudo su//g; #####remove string "su" or "sudo su"
$commandline=~ s/^\s+|\s+$//g;  ####remove trailing and leading whites
