.Sh DESCRIPTION
|
||
|
|
.Nm
|
||
|
|
reads lines from the standard input and copies them to the standard
|
||
|
|
output with a probability of 1/denominator.
|
||
|
|
The default value for
|
||
|
|
.Ar denominator
|
||
|
|
is 2.
|
||
|
|
.Pp
|
||
|
|
The options are as follows:
|
||
|
|
.Bl -tag -width Ds
|
||
|
|
.It Fl e
|
||
|
|
If the
|
||
|
|
.Fl e
|
||
|
|
option is specified,
|
||
|
|
.Nm
|
||
|
|
does not read or write anything, and simply exits with a random
|
||
|
|
exit value of 0 to
|
||
|
|
.Ar denominator Ns -1 ,
|
||
|
|
inclusive.
|
||
|
|
.It Fl r
|
||
|
|
The
|
||
|
|
.Fl r
|
||
|
|
option guarantees that the output is unbuffered.
