This is our thrid post on finding different hardware devices information attached to a system. Already covered topics are
Get BIOS, Firmware, Hardware And Drivers Details in Linux/Unix
In this post we will see other commands which will give you complete picture of your system hardware.
lshw is latest one in this list which will show you hardware information. This
Example1 : Get all the hardware attached to a machine

Example4: To display hardware information in GUI we can use below commands
hardinfo
or
sysinfo
There are other commands available in linux such as hwinfo, udevadm which will give us information about hardware installed.
