I'm having to use an old version of perl on some systems and it doesnt like the format of the open
my $file = shift @ARGV || 'cpuuse.out'; open my $fh, '<', $file or die $!; Is there another way of opening the file in the same way but different code? Thanks, Jase The sum function is just a convieniece function (which is why it is part of List::Util and not imported by default). You can get the same effect like this my $sum = 0; $sum += $_ for @cpu; print $sum / @cpu; Disclaimer: This e-mail may contain confidential or privileged information and is intended solely for the addressee.
