This command bring down services and remove it from the scandir.
free [ -h ] [ -P ] service...
This command expects to find an already supervised service. If the state of the service is already up, the free command stop it first. Subsequently, service is unsupervised from the scandir, freeing the memory used by the service.
Multiple services can be freed by separating their names with a space.
In case of module service type, all services declared within the module will also be unsupervised. The -P has no effect on the services within the module and only affects the module’s dependencies.
This command handles interdependencies.
-h: prints this help.
-P: Do not handle service dependencies. In such cases, the free command will not attempt to stop the services that are dependent on the service, regardless of their current state.
Free a service by handling its dependencies.
66 free foo
Free the service without handling any dependencies
66 free -P foo
