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

For Ubuntu (checked with 12.04)

You can get list of all services and select by color one of them with 'grep':

sudo service --status-all | grep postgres

Or you may use another way if you know correct name of service:

sudo service postgresql status
