service

The service --status-all command will list all services on your Ubuntu Server (both running services and not running services):

service --status-all

Using the grep command, we can filter the output to show only the running services:

service --status-all | grep '\[ + \]'

To list Ubuntu services that are not running, type:

service --status-all | grep '\[ - \]'

The service command can be used to list services in all Ubuntu releases, including Ubuntu 17, 16.04, and 14.04.

systemctl

To list all running services on Ubuntu, Type:

systemctl list-units

Count

running services

service --status-all | grep -c '\[ + \]'

not running services

service --status-all | grep -c '\[ - \]'

all services

service --status-all | grep -c ''

Although service is still working on ubuntu 22, it is recommended to use systemctl for list running services as follows:

sudo systemctl list-units --state running
