Hi there,
okay i am trying to figure out how to incorporate Matt's and Ken's
advice and fit it in with the current way I've been interacting with the tot
here is what I am doing. I am trying to collect all the output after
sending the command 'show interfaces $interface' and stop the collection
whent eh prompt has been reached.
There is no need to check for 'more' or screen scrolling as I've turned
that option off.
A good portion of the script is shown below. The output of the command
is even further below.
Cheers,
Noah

my $command = Expect->spawn("$cmd");
$command->log_stdout(0);
$command->expect($timeout, -re => "Password:") or die("Failed to get
password prompt");
print $command "$password\r";
my $prompt = "$user\@[^>]+>";
$exp->expect($timeout, [ qr/$prompt/ => sub { $_[0]->send("set cli
screen-length 0\n"); } ]);
$exp->expect($timeout, [ qr/$prompt/ => sub { $_[0]->send("show
interfaces $interface\n"); } ]);
$command->expect(1, [ qr/$prompt/ => sub { my $exp = shift;
exp_continue; } ] );
$exp->expect($timeout, [ qr/$prompt/ => sub { $exp->send("exit\n"); } ]);
exit 0;
