try on your machine
The command "sudo sa --user-summary" is used to display a summary of CPU usage and other statistics for individual users on a Linux system.
Here's an explanation of each component of the command:
- "sudo" is a command that allows a user with administrative privileges ("superuser" or "root" access) to execute a command as another user or with elevated permissions. It prompts for the password of the current user to verify authorization before executing the command.
- "sa" is short for "system activity" and is a command that collects and displays various system statistics, including CPU usage, system calls, disk activity, and more.
- "--user-summary" is an option or flag for the "sa" command. It instructs the command to provide a summary specifically for each individual user, rather than showing overall system activity. It will display CPU usage breakdowns and other statistics for each user separately.
In summary, "sudo sa --user-summary" lets you view a summary of CPU usage and other statistics for each user on a Linux system, helping administrators monitor and understand the resource utilization of individual users.
