Hi,

This could be a very simple question but I was trying to super search this question in perlmonk but could not find the answer. Also, I tried to search the Getopt::Long documentation but to no avail.

Basically, I want the code to give an exit if the value to the optional argument was not supplied. I have this code. 
#!/usr/bin/perl

use warnings;
use strict;
use Getopt::Long;

my ($option_test);
GetOptions( "test=s" => \$option_test );

print 'option is not defined.' if ( ! $option_test );

See below what happens when I run the code above. 
$ test.pl
option is not defined.

$ test.pl -t
Option test requires an argument
option is not defined.

[download]
So, the 2 tests above shows that if I do not supply a proper argument to the -t option, then it is as if I did not use the -t option at all.

What I want is for Getopt::Long to exit if it gives this message "Option test requires an argument".

Thanks in advance.
