How do I make these changes to my directory from the command line? (RoR)

Question

Currently our post resources are nested under topics. We should organize our posts_controller and post views in the same manner. Make the following directory changes: Try to make these changes from your command line.

app/controllers/posts_controller.rb -> app/controllers/topics/posts_controller.rb

How do I make the changes using the command line?

Answer 1

$ mkdir app/controllers/topics
$ mv app/controllers/posts_controller.rb app/controllers/topics/posts_controller.rb

Generically, you'd want to use mkdir -p in case app/controllers/topics exists already.
