A service is a program that runs in the background.

We can add to remove services for a better experience. For example we want our NetworkManager service to automatically start on boot, so when we login, we are connected to a network.

There are two scopes of services

  • user scope: by adding the flag --user to any of the commands, we will be running the service as a user. If it is enabled it will start only once the user logs in.
  • system scope: The service will start when the system boots up. (managed by the init system, systemd).

Managing services


If you are trying to do this in user scope, then omit the sudo and add the --user flag.


  • sudo systemctl start <service_name>: to start a service
  • sudo systemctl enable --now <service_name>: starts the service but also makes sure it is running when you turn your computer on / log in. If you don't need the service to run/start right now, you can omit the --now flag.
  • sudo systemctl stop <service_name>: to stop a running service.
  • sudo systemctl disable <service_name>: Stop a service from running on startup.

Some commands that are useful for debegging:

  • sudo systemctl | grep running : see all the services that are running.
  • sudo systemctl list-unit-files | grep enabled: see the enabled services
