Perl Getopt Using Same Option Multiple Times

Question

In Perl getopts, is it possible to use the same option multiple times but with different values ? I want to give the user the option of entering different grid coor

Answer 1

As documented in Getopts::Long - Options with multiple values:

#!/usr/bin/perl
use strict;
use warnings;

use Getopt::Long;

GetOptions(
    "coords=s" => \my @coords,
);

print "$_\n" for @coords;

Executed using:

my_grid.pl --coords=10,12 --coords=-18,30 --coords=4,-25

Outputs:

10,12
-18,30
4,-25
