So i was wondering the other day how to show what raberry pi i had, rather than opening it up.

you can install lshw and it can list all your hardware

Install it with

BASH

uname -r

which should give you something like this (but probably not exactly this... hopefully)

BASH

sudo lshw

Here is what it found on mine:

BASH

.raspberrypi
    description: ARMv7 Processor rev 5 (v7l)
    product: Raspberry Pi 2 Model B Rev 1.1

If you want to see what version of rasbian you are running use the command:

BASH

uname -a

uname by its self does not give much useful info...
