Monks,

I have a relatively large script using Expect.pm to automate nightly processing and backups. Part of the script spawns the backup shell script as follows: 
my $exp = new Expect;
$exp = Expect->spawn('sudo sh /usr/local/scripts/pre_backup.sh')
        or die "Cannot spawn pre-backup: $!\n\n";
if ($exp->expect(undef, 'Password')) {
        $exp->send("$password\cM");
}

This works fine, it spits the password out to sudo, and sudo accepts it. The problem is, I then need to interact with the backup script (pre_backup.sh): 
if ($exp->expect(undef, 'any key to continue')) {
        $exp->send("\cM");
}

...but Expect never sees the 'Press any key to continue' prompt from the pre_backup script, it is still looking for text from the sudo pty, not the second pty which sudo itself spawns.

My question is this: is there a way to use the same Expect object to interact with two different ptys, such as in this case? Is there a work-around that anyone can think of?

Thanks for any help,
scott.
