lshw (Hardware Lister) command gives a comprehensive report about all hardware in your system. This displays detailed information about manufacturer, serial number of the system, motherboard, CPU, RAM, PCI cards, disks, network card etc.,
Using lshw, you can get information about the hardware without touching a screwdriver to open the server chassis. This is also very helpful when the server is located in a remote data center, where you don’t have physical access to the server.
In our previous article, we discussed about how to display hardware information on linux using dmidecode command. In this article, let us review how to view the hardware specifications using lshw command.
dmidecode command reads the system DMI table to display hardware and BIOS information of the server. Apart from getting current configuration of the system, you can also get information about maximum supported configuration of the system using dmidecode.

This article provides an overview of the dmidecode and few practical examples on how to use dmidecode command.
