RANDOM(6)

NAME
random - select lines randomly from a file

SYNOPSIS
/usr/games/random [ -er ] [ divisor ]

DESCRIPTION

random acts as a text filter, randomly selecting lines from its standard input to write to the standard output. The probability that a given line is selected is normally 1/2; if a divisor is specified, it is treated as a floating-point number, and the probability is 1/divisor instead.

OPTIONS

-e  Don't read the standard input or write to the standard output. Instead, exit with a random exit status between 0 and 1, or between 0 and divisor-1 if divisor is specified.

-r  Don't buffer the output. If -r is not used, output is buffered in blocks, or line-buffered if the standard output is a terminal.
