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

Maybe what you want is the ps command;

ps -ef

will show you all processes running. Then if you have an idea of what you're looking for use grep to filter;

ps -ef | grep postgres
