You could feed your examples to the following program and see what happens...
The important part is the "o=s" telling Getopt to look for -o switches with a string argument and the array-ref telling it
to accumulate the -o arguments into an array.
use strict;
use warnings;
use Getopt::Long;
my @o_list;
unless ( GetOptions ("o=s" => \@o_list) ) {
print "GetOptions had problems parsing ARGV!\n";
}
print "List of -o things: ", join(", ", @o_list), "\n";
print "Unparsed arguments: ", join(", ", @ARGV ), "\n";

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
