Subject: Computing folder size - do you have something cleaner than this ?

Hi guys,

I'm computing an approximate folder size by summing the sizes of its
files, recursively, with the following code:

def item_size(name)
  if File.directory?(name)
    (Dir.entries(name) - ['.','..']).inject(0) { |sum,file| sum +
item_size(File.join(name,file)) }
  else
    File.size(name)
  end
end

Another version would be:

def item_size_2(name)
  Dir[name+'/**/*'].inject(0) { |sum,file| sum + (File.directory?
(file) ? 0 : File.size(file)) }
end

can anyone think of a shorter or more readable way of writing it ? Do
you know a library that would do this ?

cheers,
