So, you're looking for this line..

Using this line, right?

Instead of collecting everything in $before, use the power of perl::Expect
and regular expressions to do something like this:

my $string = "Not found";
$ssh->expect(30,
             [ ".*bytes total.*bytes free.*" => sub {
                 my $self = shift;
                 $string = $self->match();
                 exp_continue;
               } ],
             '#'
             );
$string =~ m/([0123456789]+) bytes total.*([0123456789]+) bytes free/;
print "Total bytes: $1\n";
print "Free bytes:  $2\n";

My testing seems to suggest this will work much better than what
you're trying to do.

Cheers,
Tanner
