Try this:

Dir.glob('/Users/me/2testing/dir2/**/*') do |fname|
  next if File.directory?(fname)

  File.open("temp.txt", "w") do |temp_file|
    IO.foreach(fname) do |line|  #fname is from outer loop
      new_line = line.gsub("hello world", "goodbye")
      temp_file.print(new_line)
    end

    File.delete(fname)
    File.rename("temp.txt", fname)
  end
end


**  means to look in the current directory and all subdirectories for 
the filenames *, where * means all file names(including directory 
names).
