**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.
