 i don't think this reproduces the exact ouput as `ls /bin | random -s 8`.
 
 `random 8` will print each input line with a probability of 1/8th.
 
 `random -s 8` on the other hand will print a random line out of every 8 lines of input. this means that for a static number of input lines `random -s 8` will always produce the same number of output lines, wheras the number of lines returned by `random 8` will be different for each run.
 
 cheers
