⁹You can also use the operating system in order to pass random seeds to your program. Try the commands set x = ‘< /dev/urandom tr -dc "[:digit:]" | head -c9 | awk ’printf "%d",$1’‘ ; echo $x and set x = ‘perl -e ’srand();print int(100000000*rand());’‘ ; echo $x. Use the value of the variable x for a seed.
