With the class argument, you can restrict the listing to components of a particular class.
By default, only the components in the current namespace are listed (see the change-namespace command). If no current namespace has been selected, only top-level components are shown. The component argument can be used to override the current namespace.
With the -all flag, list all components, regardless of where they live. With the -recursive flag, in addition to listing all components that are in the selected namespace, also list all components in the namespaces below it. With -t, list only top-level components. The -s and -v flags select a briefer listing (default), and a more verbose listing, respectively.
Example of default output. Columns are explained by the bottom row.
board chassis_qsp_x86 ethernet_switch0 ethernet_switch slot class name not instantiated, if applicable
Example of verbose output. Components are printed in bold and columns for the connectors are explained by the bottom row:
board chassis_qsp_x86 ethernet_switch0 ethernet_switch device0 ethernet-link any board.mb.sb:eth_slot device1 ethernet-link any service_node_cmp0:connector_link0 connector type direction destinations, if any
The list-components command returns a list of components when used in an expression. The get-component-list command just returns such a list.
