rails g sessions controller in rails

rails g controller sessions new create destroy

Explanation for each step:

1. rails: The Rails command-line tool used to interact with your Rails application.
2. g controller: Short for generate controller, this command creates a new controller in your Rails application.
3. sessions: The name of the controller being generated, in this case, it's named "sessions."
4. new create destroy: These are the actions/methods being generated inside the "sessions" controller. It creates three methods: new, create, and destroy which correspond to the actions for displaying a form, creating a session (typically for logging in), and destroying a session (logging out), respectively.
