random - random lines from a file or random numbers
random [-er] [denominator]
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.
