title: aws s3 ls Unknown options: --recursive
body: <p>I am trying to list the contents of an Amazon S3 bucket using the following command (<a href="http://docs.aws.amazon.com/cli/latest/reference/s3/ls.html" rel="nofollow">documentation</a>):</p>
  
  <pre><code>aws s3 ls s3://mybucket --recursive
  </code></pre>
  
  <p>However, I get the following error:</p>
  
  <pre><code>Unknown options: --recursive
  </code></pre>
  
  <p>The following is the version information for my Ubuntu Linux EC2 instance:</p>
  
  <pre><code>$aws s3 ls --version
  aws-cli/1.2.9 Python/3.4.3 Linux/3.13.0-85-generic
  </code></pre>
  
  <p>How can I enable the <code>--recursive</code> option on my aws-cli? </p>
