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.
