example:
1 = chinese
2 = sushi
3 = pizza

  • change seq 1 3 for a bigger array size.
  • decreasing the count= parameter will take longer, with higher randomization.
  • you can also change the blocksize bs= parameter, if you wish to.

update:

this is a sh/bash compliant version (output is not as nice though):

while :; do for i in `seq 1 3`; do if ( echo -n 'bit match: '; dd if=/dev/urandom count=128 bs=1 | grep -c '1' ); then echo -e "\n\nyour match: $i" && break 2; fi; done; done
