GetOptions should print a warning and return a false value in that
case. What version of Perl and Getopt::Long are you using? Try
running the following code. If it does not die, then there is a
problem outside of your code.
#!/usr/bin/perl
use strict;
use warnings;
use Getopt::Long;
for my $args ([qw/-n a/], ["-n"]) {
@ARGV = @$args;
GetOptions(
"n|name=s" => \my $name,
"a|age=s" => \my $age,
"s|sex=s" => \my $sex
) or die "bad options\n";
print "[$name] @ARGV\n";
}
