title: Kill a process from website
body: <p>I have the code and everything which is:</p>
  
  <pre><code>     pkill python
  </code></pre>
  
  <p>However I wanted to run it from a php script like this:</p>
  
  <pre><code>  echo shell_exec("pkill python");
  </code></pre>
  
  <p>I get an output which says:</p>
  
  <pre><code>bash: pkill: (1503) - Operation not permitted
  </code></pre>
  
  <p>I know what the problem is, which is that pkill is su command. Anyway to change this so that the php script can run it?</p>
