If you wanted to see a list of services available on your Linux server/desktop, try the following command:

systemctl list-unit-files --type=service

Upon executing this command, you'll be able to see a list of services along with their statuses i.e whether the service is enabled or disabled.

This can come in handy if you want to know the status of a specific service like nginx:

systemctl list-unit-files --type=service | grep "nginx"

Hope you found this tip useful.
