I've seen a couple of questions recently about the Ops Center CLI - what it can do and where it's documented - so I thought I'd give you a brief rundown.
The Ops Center command-line interface lets you perform many of the same tasks that you can perform through the UI, including asset discovery and management, OS and firmware provisioning, and administrative tasks like managing roles and jobs. Not every UI action has an equivalent CLI action, but there are several tables in the CLI guide that explain what it can and cannot do.
The CLI also gives you the ability to script some Ops Center actions, letting you automate regular tasks and run them without using the UI.
For more information about the CLI, take a look at the CLI guide.
