sudo systemctl start SERVICE: Use it to start a service. Does not persist after rebootsudo systemctl stop SERVICE: Use it to stop a service. Does not persist after rebootsudo systemctl restart SERVICE: Use it to restart a servicesudo systemctl reload SERVICE: If the service supports it, it will reload the config files related to it without interrupting any process that is using the service.systemctl status SERVICE: Shows the status of a service. Tells whether a service is currently running.sudo systemctl enable SERVICE: Turns the service on, on the next reboot or on the next start event. It persists after reboot.sudo systemctl disable SERVICE: Turns the service off on the next reboot or on the next stop event. It persists after reboot.systemctl is-enabled SERVICE: Check if a service is currently configured to start or not on the next reboot.systemctl is-active SERVICE: Check if a service is currently active.systemctl show SERVICE: Show all the information about the service.sudo systemctl mask SERVICE: Completely disable a service by linking it to /dev/null; you cannot start the service manually or enable the service.sudo systemctl unmask SERVICE: Removes the link to /dev/null and restores the ability to enable and or manually start the service.
