I've been advised that while this looks good, it doesn't
generate the kind of guaranteed results that DBAN does.
E.g., it doesn't conform to the DoD spec. I too would have
thought that

#!/bin/sh
num_wipes=[number of times you want to wipe the disk]
for i in `seq 1 $num_wipes`; do
	dd if=/dev/urandom of=[HD device node]
done

would have done the trick, but I'm told by reliable
computer-scientist friends that it does not. Use DBAN
instead.
