1. first, you declare the variable
2. then, you pass it as Hash to the function that reads it ..
3. then, again deal with same variable in the usage()...
Is there a way I have to deal with the variable just once??
Maybe foobar(\my %hash); or foobar(my $href = {...}); can get you part of the way there.
I only glanced at them, but you might make use of Getopt::ArgvFile (specifying files that are automatically read?) or Getopt::Lucid (which talks about reading in config file in its synopsis).

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).
