Gilbert,

dd is your what you're looking for I think,, something like

    % dd if=/dev/random of=/my/file.junk count=1000000

Maybe dev/random is not such a good choice, and also look into the
size arguments too (ibs=, obs=), something as a factor of 1024 would
probably be nice. Make sure 1000000 is a Mr.
