How to check if a particular service is running on Ubuntu

Question

I do not know the service\'s name, but would like to stop the service by checking its status.

For example, if I want to check if the PostgreSQL service is running or no

Answer 1

I don't have an Ubuntu box, but on Red Hat Linux you can see all running services by running the following command:

service --status-all

On the list the + indicates the service is running, - indicates service is not running, ? indicates the service state cannot be determined.
