of the x11 based games. I'm not going to tag the originals with bsd_44_lite and do this in two stages since it's just not worth it for this collection, and I've got directory renames to deal with that way. Bleah. Submitted by: jkh

|
.SH NAME
|
|
factor, primes \- factor a number, generate primes
|
|
.SH SYNOPSIS
|
|
.B factor
|
|
[ number ] ...
|
|
.PP
|
|
.B primes
|
|
[ start [ stop ]]
|
|
.SH DESCRIPTION
|
|
The
|
|
.I factor
|
|
utility will factor integers between -2147483648 and 2147483647 inclusive.
|
|
When a number is factored, it is printed, followed by a ``:'',
|
|
and the list of factors on a single line.
|
|
Factors are listed in ascending order, and are preceded by a space.
|
|
If a factor divides a value more than once, it will be printed
|
|
more than once.
|
|
.PP
|
|
When
|
|
.I factor
|
|
is invoked with one or more arguments,
|
|
each argument will be factored.
|
|
.PP
|
|
When
|
|
.I factor
|
|
is invoked with no arguments,
|
|
.I factor
|
|
reads numbers, one per line, from standard input, until end of file or error.
|
|
Leading white-space and empty lines are ignored.
|
|
Numbers may be preceded by a single - or +.
|
|
Numbers are terminated by a non-digit character (such as a newline).
|
|
After a number is read, it is factored.
|
|
Input lines must not be longer than 255 characters.
|
|
.PP
|
|
The
|
|
.I primes
|
|
utility prints primes in ascending order, one per line, starting at or above
|
|
.B start
|
|
and continuing until, but not including
|
|
.B stop.
|
|
The
|
|
.B start
|
|
value must be at least 0 and not greater than
|
|
.B stop.\&
|
|
The
|
|
.B stop
|
|
value must not be greater than 4294967295.
|
|
The default value of
|
|
.B stop
|
|
is 4294967295.
|
|
.PP
|
|
When the
|
|
.I primes
|
|
utility is invoked with no arguments,
|
|
.B start
|
|
is read from standard input.
|
|
.B Stop
|
|
is taken to be 4294967295.
|
|
The
|
|
.B start
|
|
value may be preceded by a single +.
|
|
The
|
|
.B start
|
|
value is terminated by a non-digit character (such as a newline).
|
|
The input line must not be longer than 255 characters.
|
|
.SH DIAGNOSTICS
|
|
Out of range or invalid input results in `ouch' being
|
|
written to standard error.
|
|
.SH BUGS
|
|
.I Factor
|
|
cannot handle the ``10 most wanted'' factor list,
|
|
.I primes
|
|
won't get you a world record.
