if you're not after a repeatable set, seed it every time with timer value. that's pretty close to something resembling a random set of numbers.
btw there's only ever a theoretically possible set of true random numbers, and nothing like it in programming or life/nature. and the harder mathematicians and/or programmers strive to get to truly random number sets, the more they approach a truly contrived/artificial set.
just a matter of how random you want your set of numbers to appear. seeding with timer seconds or milliseconds value works for me on most occasions.
the hardest line to type correctly is: stty erase ^H
