How about using Dir.entries( "." ) - this is more portable and likely
faster, too.

You mean "with the command processor".  For simple usage you can resort to
IO.popen() (some caveats apply for windows).  An example:

IO.popen( "cmd.exe", "r+" ) do |cmd|
  Thread.new(cmd) do |io|
    while line = io.gets
      puts line
    end
  end

  cmd.puts "dir"
  cmd.puts "cd \\"
  cmd.puts "dir"

  sleep 3
end


Else there is expect for Ruby.
