Processes, signals and job control

Objectives 103.5 and 103.6 cover process management and signals, and both are asked with exact commands. This guide finds processes three ways, reads the STAT column, stops and continues a real process with signals, shows the exit status a kill produces - and includes the moment the capture killed its own shell, which is the most useful thing on the page.

This guide includes

Use this for the process and signal objectives. This matters because pkill -f matches the whole command line - during this capture it killed its own shell, which is the lesson.

Before you start

  1. Finding a process, three ways

  2. The STAT column, which is examined directly

  3. Signals, and the two that matter

  4. Priority, and who is allowed to raise it

  5. The capture killed its own shell, and that is the lesson
