title: How to echo the current directory via . in Linux?
body: <p>In Linux <code>.</code> is used to refer to the current directory, but I need to know instead using <code>pwd</code> what is the current directory via <code>.</code>.</p>
  
  <p>I tried <code>echo $(.)</code> and<code>echo .</code> but doesn't work... any solution to get the same output as <code>pwd</code> but using <code>.</code>?</p>
