My goal is to search over all files,  identify all =
that are directories 
and then do something to each directory.  I don't n=
eed to go into 
directories recursively yet.

The fact that Dir.foreach returns strings seems odd=
 to me.  All advice 
appreciated.


#!/usr/local/bin/ruby

dpath =3D Dir.getwd

Dir.foreach(dpath) do
  |x|
  ddir =3D File.join(dpath,x)
  if File.directory?(ddir) && x !=3D "=
." && x !=3D ".." then
    puts %x{du -sh #{x}}
  end
end

Try:

dirs =3D Dir.entries(".").reject{|e| /\.{1,2}/ =3D~ e}.fi= nd_all{|e| File.directory? e}

At this point you have a list of directory names. You can do whatever= you like to that list using .each(), .inject(), .collect(), etc.
