I'm spending lots of time looking thru perl functions but not finding something to give me a quick reading on the size of a directory.
How is that task handled in perl?
First of all, you can use du:
$output = `du -sk /etc`; ($kilobytes) = $output =~/^(\d+)/ or die;
There's also Tie::DiskUsage module: http://search.cpan.org/search?module=Tie::DiskUsage
You might also take a look at du from ppt: http://search.cpan.org/src/SDAGUE/ppt-0.12/bin/du
