Which command lists usage instructions for each puppet resource type?

The command that lists usage instructions for each Puppet resource type is "puppet describe." This command provides detailed information about the various resource types available in Puppet, including their attributes and any default values. It is particularly useful for users who are exploring Puppet's capabilities or need clarification on the specific properties of resources they plan to manage.

In contrast, the "puppet resource" command is primarily used to display the current state of a resource or to create/update a resource on the agent. "Puppet apply" is focused on applying a manifest to configure resources on a node and does not provide usage instructions. Lastly, "puppet inspect" is not a standard command used in the context of listing resource-type instructions; instead, it is generally used in conjunction with inspecting current resource configurations.

Overall, "puppet describe" serves the specific function of outlining how to use different resource types, making it the appropriate choice for acquiring that information.
