This document will cover some very basic system administration commands used in Linux to display information on the installed hardware. These should all be performed as the root user via SSH.



$ hwinfo –short
The above command will display a list of information about most of the hardware installed.
$ df -h
The above command will display disk file system information.

$ free -h

The above command will display information about the RAM installed and  swap space.



This is not meant to be an exhaustive guide, but a few commands for quickly checking information on hardware installed in a computer with Linux installed.
