Hi Monks of Wisdom, subject explains. I have the following code:

#!/usr/bin/perl -w
$dir = "some_dir";
@file_list = glob ("$dir/*");

GetOptions (
 "f=s" => \@file_list,
);
foreach (@file_list) { print { $_\n"; }
[download]

I want to get following behaviour: If I don't give -f option, script must assume whole list in the directory must be taken to the @file_list. If I give only the number of -f arguments, it must overwrite the default. However, it doesn't. Getopt::Long doesn't overwrite but appends the -f args. For the case:

#!/usr/bin/perl -w
$dir = "some_dir";
$file = "$dir/some_file");

GetOptions (
 "f=s" => $file,
);
[download]

... it does overwrite, rather than append. Why is the behaviour for arrays different? Is there a way to switch off append behaviour for arrays? Perl version is 5.8.0. Regards!
