I have a hash which contain netflow statistic data. And I want to sort it by total number of packets and total size.

My code is like this:

%flows = sort {$flows{$b}{pkts} <=> $flows{$a}{pkts}
                                       or 
                     $flows{$b}{size} <=> $flows{$a}{size} } %flows;

But why not it work normal? What's wrong with it?

thanks!
