SYNOPSIS¶
| primes |
[-d]
[start
[stop]] |
DESCRIPTION¶
The
primes utility prints primes in ascending order, one per
line, starting at or above
start and continuing until,
but not including
stop. The
start
value must be at least 0 and not greater than
stop. The
stop value must not be greater than the maximum possible
value of unsigned integer types on your system (4294967295 for 32-bit systems
and 18446744073709551615 for 64-bit systems). The default value of
stop is 4294967295 on 32-bit and 18446744073709551615 on
64-bit.
When the
primes utility is invoked with no arguments,
start is read from standard input.
stop is taken to be 4294967295 on 32-bit and
18446744073709551615 on 64-bit. The
start value may be
preceded by a single ‘+’. The
start value is
terminated by a non-digit character (such as a newline). The input line must
not be longer than 255 characters. When given the
-d
argument,
primes prints the difference between the current
and the previous prime.
DIAGNOSTICS¶
Out of range or invalid input results in an appropriate error message being
written to standard error.
BUGS¶
primes won't get you a world record.
