On a Linux system, there are several commands and utilities that you can use to find information about the system configuration and hardware. Some of the most commonly used commands and utilities for this purpose include:
uname: The uname command displays information about the Linux kernel and the system. For example:$ uname -a
This will display the kernel name, version, and other information about the system.
lshw: The lshw command is a hardware lister that displays detailed information about the hardware on the system. For example:$ sudo lshw
This will display a list of the hardware on the system, including the processor, memory, storage devices, and other peripherals.
lscpu: The lscpu command displays information about the CPU on the system. For example:$ lscpu
This will display the CPU model, speed, architecture, and other information about the processor.
lsblk: The lsblk command lists the block devices on the system, along with their device names, sizes, and mount points. For example:$ lsblk -o NAME,SIZE,MOUNTPOINT
This will display a list of the block devices on the system, including the hard drives, along with their sizes and mount points (if they are mounted).
dmidecode: The dmidecode command is a utility that reads the system's DMI (Desktop Management Interface) table and displays information about the hardware, including the motherboard, processor, memory, and other peripherals. For example:$ sudo dmidecode
This will display a list of the hardware on the system, along with detailed information about each component.
Note: The specific options and syntax for these commands may vary depending on your Linux distribution and version. Consult the man pages or documentation for your system for more information.
