Project 1.3

Hands-On Project 1.3:  Viewing disk and Process Information in linux 

Time Required: 10 minutes

 Objective:  Viewing disk and Process Information in linux .

Required Tools and equipment: A Fedora 30 Linux virtual machine or computer.

Description: : In this project, you use a command-line and GUI process tool in Linux to look at running processes. You also explore the Disks utility.

1. Log on to your Linux computer, if necessary. Click Activities, click Show Applications, click utilities, and then click Terminal.

2. Type pstree and press enter to see a snapshot of the hierarchy of running processes. To paginate the output, type pstree | more and press enter. Press space to advance to the next page. Press q to quit.

3. To see a real-time view of running processes, type top and press enter. Top lists the “top” CPU-using processes first. The display changes as different processes use the CPU. Leave top running.

4. Click Activities, click Show Applications, click utilities, and then click System Monitor. This application is similar to Task Manager in Windows. Running processes are listed in alphabetical order by default. Scroll down until you see top. Click top and click end Process on the lower-left side of the window. Click end Process to confirm. You see in the terminal window that top stops.

5. Scroll up near the top of the window and click bash. This is the process for the open terminal window. Click end Process and click end Process again to confirm. You see that the terminal window closes.

6. Click Activities, click Show Applications, click utilities, and then click disks. Browse the installed disks and look at the information in the right pane as you click each disk in the left pane. You’ll notice that storage in Linux is represented much differently than in Windows. You’ll explore storage in more detail in Module 4, “File Systems.” Close all open windows and shut down your Linux computer.
