RE: passing a password

Thanks for the help.  Not sure why I did that backwards in the first
place, but even done the right way as you've shown, it does not accept
the password.  However, the Expect module does the trick flawlessly:

------------------
my $queue = $_[0];
my $command = "/usr/sbin/cupsaddsmb -U admin -v $queue";
my $password = "password\n";
my $timeout = 5;

my $addsmb = Expect->spawn("$command") 
	or die "Cannot spawn $command $!\n";

$addsmb->expect($timeout,
	[ qr/SAMBA: /i, sub { my $self = shift;
		$self->send("$password");
                exp_continue_timeout; }]
        );
$addsmb->soft_close();
-------------------

Thanks for the help...I never would have stumbled across Expect.
