How to check if a particular service is running on ubuntu?

Question

How to stop the service for which I don’t know the name by checking it’s status? For example, to check if a PostgreSQL service is running or not but I don’t know the service’s name, how to check the status of it? 

Answer 1

To check the status of the running services on RedHat Linux, you can use the below command: 

service --status-all

In the output, + means the service is running, - means the service is not running and ? means the service state can’t be determined.
