lshw

The 'lshw' (List Hardware) command in Linux/Unix is a powerful tool for extracting detailed information about the system's hardware configuration. This tool retrieves data from files in the '/proc' directory and is capable of reporting on a wide array of components, including memory configuration, CPU details, firmware version, mainboard configuration, cache memory, bus speed, and more
