Checking running processes in Linux

I want to give you a good article which describes in detail the process and commands to manage Linux processes. There are too few books which give good examples of process management commands. And when you work with servers one of the most important things is process management.
Many people have a poor grasp of the official Linux documentation. Because it usually just says what the command is and what it does. Without detailed explanations.
I often don't understand official documentation either. I read it twice, but I still don't understand it. That happens very rarely, but I had some problems with Linux. I recommend you to read an article with information about checking the running processes of Linux https://www.hostforweb.com/article/how-check-running-processes-linux/ It is very well laid out and makes sure that you understand everything once you read it. At least for me, it was enough to understand and apply the commands.
