title: Find nginx version?
body: <p>I have installed nginx on Debian 7 with the following steps</p>
  
  <pre><code>sudo apt-get update
  sudo apt-get upgrade
  sudo apt-get install nginx
  sudo service nginx start
  </code></pre>
  
  <p>I have confirmed that this starts nginx by accessing the hostip from the browser. How do I find out the version of nginx?</p>
  
  <p><code>nginx -v</code> fails with the '<code>command not found</code> error</p>
  
  <p>I verified that nginx exists in the usr/sbin directory and that directory is added to the $PATH variable</p>
