Listing services in Ubuntu or any other Linux system allows you to check whether necessary services are running correctly or not. In Ubuntu you can easily list installed all running and non running services using service and systemctl command.
Method 1 : List Services Using systemctl Command
Open the terminal app using (ctrl+alt+t) shortcut or via the Show Apps and run below command to list all Ubuntu installed services.
systemctl list-units --type=service --all
List only the running services with systemctl command.
systemctl list-units --type=service --state=running
Method 2 : List Services Using Service Command
Open the terminal application (ctrl+alt+t) and run below command to list all Ubuntu Linux installed services.
service --status-all
List only the running services:
service --status-all | grep '\[ + \]'
List services that are not running:
service --status-all | grep '\[ - \]'
