i7z is a command-line tool specifically designed for Intel CPUs (i3, i5, and i7) to provide real-time reporting. It gives detailed information about the CPU frequency, temperature, and utilization. This tool is useful for monitoring the performance and health of the CPU in Linux systems.

Use case 1: Start i7z in superuser mode

Code:

sudo i7z

Motivation:

Running i7z in superuser mode allows you to access and display detailed information about the CPU, including various performance metrics, which may not be available in regular user mode. Superuser mode is required for interacting with the CPU registers and other low-level information.

Explanation:

• sudo: This command is used to execute i7z with superuser privileges. The sudo command allows regular users to execute a command as the superuser or another user.
• i7z: The i7z command starts the i7z tool in real-time reporting mode.

Example Output:

**************************************************
** This program requires root privileges.       **
** This program must be executed as super-user. **
**************************************************

When executed without proper superuser privileges, i7z displays a message indicating that root privileges are required.

Conclusion:

The i7z command is a handy tool for monitoring the performance and health of Intel CPUs in real-time. By using the command in superuser mode, you gain access to detailed information about the CPU, including frequency, temperature, and utilization. Monitoring these metrics can help optimize system performance and identify potential issues.
