# random man page

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 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.
