First, get those IP addresses off a public site. Think before you post!

Second, you didn't understand the code I provided.

1. Why are you setting $_ in the first line of the loop?
2. Check your intendation in the map. It looks like you think the regex and hashref are part of the foreach-loop, not the map.
3. This will provide a line in @out for each line in @lines. Make sure that's what you want.
4. This will not skip lines as you were doing with the if-statement. Personally, I would do that kind of parsing in the do_it() function. But, you can do it in the map.

@lines = map {
        /(\/\w+\/\w+)\s+\w+\s+\d+\s+\d+\s+(\d+)\s+(\d+)%/;
        if ($1) {
                {
                        volume => $1,
                        available => $2,
                        free => 100 - $3,
                }
        }
        else {
                ()
        }
} split(/\n/, $space{$host});

I hope you're testing this in some test environment ...
