Exercise Your Idle System Doing Nothing

Via Unix/Linux:
cat /dev/zero > /dev/nullor
cp /dev/zero /dev/nullExplaination:
/dev/null is basically a black hole (a special null file), anything written to it goes down the drain. Anything read from it will result in nothing returned. /dev/zero is basically the same as /dev/null when writing to it, however reading it will result in a continuous stream of zeros without EOF.
