primes — generate primes

## Synopsis

primes | [`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 4294967295. The default value of `stop`

is 4294967295.

When the primes utility is invoked with no arguments, `start`

is read from standard input. `stop`

is taken to be 4294967295. 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.

## 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.
