If you need to view a list of all the services that are either running or stopped (or both) on an Ubuntu server, then you can use the following command:
service --status-all
This will print out a list of services that may look something like this:
# service --status-all
[ - ] acpid
[ + ] apache-htcacheclean
[ + ] apache2
[ + ] apparmor
[ + ] apport
[ + ] atd
[ - ] console-setup.sh
[ + ] cron
[ - ] cryptdisks
[ - ] cryptdisks-early
[ + ] datadog-agent
[ + ] datadog-agent-process
[ + ] datadog-agent-trace
[ + ] dbus
[ - ] docker
Only show Running Services in Ubuntu
If you are only interested in the running services, then we can filter by the [ + ] items:
service --status-all | grep '\[ + \]'
This will show the following:
# service --status-all | grep '\[ + \]'
[ + ] apache-htcacheclean
[ + ] apache2
[ + ] apparmor
[ + ] apport
[ + ] atd
[ + ] cron
[ + ] datadog-agent
[ + ] datadog-agent-process
[ + ] datadog-agent-trace
[ + ] dbus
[ + ] ebtables
This prints out a reduced list of only the running services.
Only show Stopped Services in Ubuntu
The opposite is also true, we can also show a list of all stopped services:
service --status-all | grep '\[ - \]'
This will show the following:
# service --status-all | grep '\[ - \]'
[ - ] acpid
[ - ] console-setup.sh
[ - ] cryptdisks
[ - ] cryptdisks-early
[ - ] docker
