I'm new here and need to implement a certain automation for linux process. But I'm stuck at a point where first I need to check a command suggestions before executing the actual command depending on certain condition. By command suggestion, I mean the suggestion or next steps displayed for a command when we press <TAB><TAB>. I have tried doing the following things but not even a single one worked:

$connection = Net::SSH::Expect(); #connection to a server
$connection->send("\t\t");
$connection->get_expect()->send("\t\t");
$connection->send("011");
$connection->get_expect()->send("011"); # octal for tab
[download]

So basically once sending <TAB><TAB> characters, I can read suggestions using $connection->read_all() but not able to figure out how to get suggestions using tab. It would be great if any of you amazing monks can guide me through this mountain!
