Here's a short Perl script that generates 10 distinct random numbers between NUM1 = 999,999,999,999 (12 digits) and NUM2=999,999,999,999,999,999 (18 digits). $range in the script is NUM2 - NUM1.

Code:

$
$ perl -e 'BEGIN {$min=999_999_999_999; $range=999_999_000_000_000_000; $n=0; $total=10}
           do { $x=sprintf("%18.0f\n",int(rand($range))+$min);
                if (not defined $rnd{$x}) {$rnd{$x}++; print $x; ++$n}
              } until ($n == $total)'
