Question: Displaying Linux Processes (Optional) Time Required: 10 minutes Objective: View processes running in Linux. Required Tools and Equipment: A computer with Linux installed or a Linux Live disk (Fedora Live Desktop in this project but others can be used) Description: In this project, you use Linux System Monitor and the ps command to view processes and performance information.

2. Start System Monitor by clicking Utilities and then System Monitor. Click the Processes tab, if necessary, and then click the % CPU column to sort from highest to lowest CPU %. Linux doesn't show a system idle process. System Monitor itself is probably the biggest user of the CPU now.
