NAME

       primes — generate primes

SYNOPSIS

       primes [-dh] [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  3825123056546413050.   The  default  value  of  stop  is
       3825123056546413050.

       When the primes utility is invoked with no arguments, start is read from standard input and stop is taken
       to be 3825123056546413050.  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.

       When given the -h argument, primes prints the prime numbers in hexadecimal.

DIAGNOSTICS

       Out of range or invalid input results in an appropriate error message to standard error.
