The Playbooks CLI is designed with flexibility, speed, and developer preference in mind. For instance, most CLI commands offer a basic and more advanced implementation per the following:
playbooks login
This will take you through an authentication flow that asks for your email and password.
playbooks login --email steve@apple.com --password ********
This will bypass the authentication flow using the credentials you already passed.
These examples demonstrate a common practice across the Playbooks CLI so you can dictate the user experience that suits your needs.
