If you need to generate a lot of numbers it's best to use the RANDOM shell variable: Just pick 4 4-digit random numbers and string them together:

Code:

printf "%04d%04d%04d%04d\n" $((RANDOM%10000))  $((RANDOM%10000)) $((RANDOM%10000)) $((RANDOM%10000))

Using this method you can generate a file with millions of pseudo random numbers in just a couple of minutes.

There is no one best way to generate pseudo-random numbers.
