body: <p>I'm new to bash and trying to understand what the script below is doing, i know <code>-e</code> is exit but i'm not sure what <code>-se</code> or what the <code>$delimiter</code> is for?</p>
  
  <pre><code>$delimiter = 'EOF-MY-APP';
  
  $process = new SSH(
      "ssh $target 'bash -se' &lt;&lt; \\$delimiter".PHP_EOL
          .'set -e'.PHP_EOL
