atop: Start and display the number of processes for each user.
$ atop -au
try on your machine

The command "atop -au" is used to start the "atop" tool in "ASCII mode" and display the CPU utilization statistics.

Here is a breakdown of the command:

  1. "atop": It is the name of the tool/command itself. "atop" is a system and process monitor that provides detailed information about the resource usage (CPU, memory, disk, network, etc.) of a Linux system.

  2. "-a": It is an option/flag that tells "atop" to display information about all system resources, including CPU, memory, swap, disk, network, and more.

  3. "-u": It is another option/flag that specifically instructs "atop" to display CPU utilization statistics.

When you run the command "atop -au" in the terminal, it will start the "atop" tool and display a real-time view of the CPU utilization, showing detailed information such as the percentage of CPU used by each process, user, and other relevant CPU statistics. The display will be in ASCII mode, meaning it will use text characters to represent the graphical elements.
