I'm trying to write a perl script to report the size of the subdirectories of a certian higher dir. I looked on perlmonks.org and from what I could gather -s $foo will report the size of a file, but I can't find any documentation on this. Like does this report bytes or kilobytes? Either way, it does not look to be right. Here is the code that I have so far, it is a reworking of some code I found on here to do a similar job. 
#!/usr/bin/perl

use strict;

my $dir = '.';
my %directories = ();
my $dirsRef = \%directories;

&find_size($dir, $dirsRef);

foreach my $key (sort keys %directories) {
   print "$key has $directories{$key} bytes in it\n";
}

sub find_size {
   my ($currentDir, $dirsRef) = @_;
   opendir DIR, $currentDir;
   my @files = grep !/^\.\.?$/, readdir DIR;
   for my $blah (@files) {
      if (-d $blah) {
         &find_size($blah, $dirsRef);
      } else {
         $dirsRef->{$currentDir} += (-s $blah);
      }
   }
}

Am I on the right track? Any suggestions are greatly appreciated.
