random — random lines from a file or random numbers

random  reads  lines from the standard input and copies them to the standard output with a probability of
       1/denominator.  The default value for denominator is 2.

       The options are as follows:

       -e      If the -e option is specified, random does not read or write anything, and simply  exits  with  a
               random exit value of 0 to denominator-1, inclusive.

       -r      The -r option guarantees that the output is unbuffered.
