linux how to get hardware details

There are multiple commands that you can run on *nix systems to get details of your hardware. Below are some popular commands used (some are not installed by default).


list hardware. It provides detailed information on the hardware configuration of the machine. It tells you memory configuration, firmware version, motherboard configuration, CPU/processor speed and type etc. You can output information in json, html format too.

to get a lot more detailed information you can use “lspci -v” or even “lspci -vv”.

see some devices use PCI Express slots.

PCI Express or PCIe provides more bandwidth and are much faster than PCI (which is an older interface).

you can use -v option to get detailed output.



very useful to get a detailed output of all your hardware. It uses libhd library. It was discontinued in older version of ubuntu but again re-continued. You can get detailed output of disk, mouse, printers, keyboard, graphics cards, controllers, network interfaces etc.
