title: Use proxy with wget on the fly
body: <p>I know that if I want to use a proxy with <code>wget</code>, I have to edit <code>/etc/wgetrc</code> or <code>~/.wgetrc</code> file and set there the proxy address and port.</p>
  
  <p>What I want to know if is there any option to use <code>wget</code> and use a proxy BUT without editing any config file.</p>
  
  <p>That's all. Thanks.</p>
