Re: [Expectperl-discuss] $exp->before() doesn't fetch all the output.

[Juan P. F. G. <jfe...@gm...>]

if its cisco a router, here is a nasty trick that worked for me...

$exp->send("$cmd");
$exp->send("!");

then wait for "routerprompt>!" in $exp->expect

let us know if worked for you :)


Good luck

Juan Pablo
