This video tutorial introduces the PS command in Linux, explaining how it lists running processes and their IDs. It covers the differences between processes in a container and a full computer, highlighting the impact of user interfaces and applications. The tutorial also explores various options available with the PS command, such as listing all processes or those by a specific user. The session concludes with a preview of the next lecture, which will focus on starting and terminating processes.
