RANDOM(6)
NAME
random -- random lines from a file or random numbers
SYNOPSIS
random [-er] [denominator]
DESCRIPTION
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 any
- thing, and simply exits with a random exit value of 0 to
denominator-1, inclusive. - -r The -r option guarantees that the output is unbuffered.
