What custom commands can you run with wp doctor?
You can create your own doctor.yml files. In this example, we want to check that MainWP Child plugin and the Classic Editor plugin are installed and active, but that the Hello Dolly plugin is uninstalled on a site.
The example yml file would look like this.
To run the plugin status yml file, the command would be:
wp doctor check --config=plugin-status.yml --all
This command would show if the two defined plugins are active and if the other plugin was uninstalled.
