Are you on GNU/Bash version 5.1[0]? A new bash variable, SRANDOM added to GNU/Bash-5.1 release, which gets its random data from the system’s entropy engine and is not lined and cannot be reseeded to get an identical random sequence. For example:

   echo "$SRANDOM"
   for r in {1..5}; do printf "%s\n" "$SRANDOM"; done

Or something like this; echo -e "$SRANDOM"{1..5}"\n"

Er, I don't think you want that.

Do you really wanted to append digits 1, 2, 3, 4, 5 to your high-quality random numbers?
