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 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.
