title: How do I get the directory where a Bash script is located from within the script itself?
body: <p>How do I get the path of the directory in which a <a href="http://en.wikipedia.org/wiki/Bash_%28Unix_shell%29" rel="noreferrer">Bash</a> script is located, <em>inside</em> that script?</p>
  <p>I want to use a Bash script as a launcher for another application. I want to change the working directory to the one where the Bash script is located, so I can operate on the files in that directory, like so:</p>
  <pre><code>$ ./application
  </code></pre>
