[-dh] [start
[stop]] |
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.
Out of range or invalid input results in an appropriate error message to standard error.
Originally by Landon Curt Noll, extended to some 64-bit primes by Colin Percival.
This primes program won't get you a world
