Process management is one of the most important responsibilities of a Linux system administrator. Every application, service, script, and command running on a Linux system operates as a process. Understanding how to monitor, control, troubleshoot, and optimize processes is essential for maintaining a stable, secure, and high-performing Linux environment.
In this lesson, students will learn how Linux processes work, how to identify resource-intensive applications, manage background jobs, monitor system performance, and control services using modern Linux tools. Learners will gain practical experience using commands such as ps, top, htop, kill, pkill, jobs, bg, fg, nice, renice, and systemctl.
By the end of this lesson, students will be able to effectively manage processes, troubleshoot performance issues, and ensure critical services remain operational.
