On any operating system, it is important to have the ability to determine what programs are running and to alter the states of these programs. In Linux, this can be accomplished by a collection of commands that allow you to display running programs, pause and restart programs, stop programs, and change program CPU priority. During this chapter you explore these topics as well as how to display essential CPU and memory information.
After reading this chapter and completing the exercises, you will be able to do the following:
Describe what processes and jobs are.
Start and stop processes and jobs.
List processes and jobs that are currently running.
Change process priority.
Display CPU and RAM information.
