Which command provides detailed information about hardware components in Linux?

The command that provides detailed information about hardware components in Linux is "sudo lshw." This utility is specifically designed to list hardware configuration details of the system in a comprehensive manner. It goes through the various hardware components, including CPU, memory, storage, and peripherals, and presents a hierarchical view of the hardware system.

Using "lshw" without "sudo" may not show all details, especially for components requiring elevated privileges, which is why "sudo" is included to ensure the command can access all relevant information. The output can provide insights into hardware specifications such as manufacturer, model, size, and capabilities, making it a powerful tool for system administrators and technicians who need to assess the hardware profile of a Linux machine.

The other commands serve different purposes: "sudo smartctl" is primarily used to monitor and control hard disk health; "sudo df" is utilized for checking disk space usage; and "sudo ifconfig" is focused on configuring network interfaces. While they all play important roles in system management, none provide the comprehensive hardware overview that "lshw" does.
