SYNOPSISprimes [-d ] [start [stop ] ]
DESCRIPTIONThe 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.
DIAGNOSTICSOut of range or invalid input results in an appropriate error message being written to standard error.
