Changes

First, it is often useful to identify the current directory. This can be done with the ''pwd'' methods of the Ruby ''Dir'' class:

Dir.pwd

=> "/home/ruby"

Changing the current working directory in Ruby is achieved using the ''chdir'' method of the Ruby ''Dir'' class. This methods takes the path of the destination directory as an argument:

Dir.chdir("/home/ruby/test")
