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