NAME

     primes — generate primes

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.
