How to get the codes of a recipe from chef server.

I was digging the way how to get the codes of a recipe from chef server. Finally I found the command:

$ knife cookbook show COOKBOOK_NAME [COOKBOOK_VERSION] [PART...] [FILE_NAME] (options)

administrator@ubuntu:~/temp$ knife cookbook show test2 latest recipes default.rb
#
# Cookbook Name:: test2
# Recipe:: default
#
# Copyright 2013, YOUR_COMPANY_NAME
