when I enter this code in my "Knoppix 7.2 Live" LX Terminal I get
the following ERROR!
far as I know "Knoppix 7.2 Live" is a form of Debian if that helps any?

Also I don't even know how to get a screenshot out of "Knoppix 7.2 Live"
I tried all 3
Ctrl+PrintScreen
Alt+PrintScreen
Shift+PrintScreen

Then when I check and am about to paste it to GIMP 2.8
it gives me the saying GIMP Message <-- Big Bold Letters
then it says under the Bold message
    There is no image data in the clipboard to paste.
geez I can't even show you my error like wtf!!!

if it's not one issue then it's another -.-
Gosh I am just trying to make a very small lightweight OS
meaning I want to make a simple Linux Operating System that is
Lightweight!
