title: php shell_exec permission denied
body: <p><code>shell_exec("touch /Users/Nerses/Downloads/ads.txt 2&gt;&amp;1")</code></p>
  
  <p>I have a problem with the PHP exec(shel_exec) function. It says that I do not have permissions to execute the command.</p>
  
  <p>How can I open these permissions?</p>
