In this lesson
Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: processes and their IDs, process states, jobs (bg, fg, nohup), signals (HUP, KILL, TERM), monitoring and priority (top, htop, nice, renice, ulimit), and scheduling with cron, at, and anacron, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
Preview the topics
- On an encoding node, ps shows several processes in state Z, marked defunct, and kill -9 has no effect on them. What are they?
- An admin starts a three-hour encoding script over SSH, and the session will close before it ends. The script must keep running after the logout. How should the admin start it?
- A cleanup script must run at 2:30 in the morning, every Sunday. Which crontab line does that?
