in order to call shell from your controller function you need to do this in your controller function :

namespace App\Controller;

use App\Controller\AppController;
use Cake\Console\ShellDispatcher; //use this shell dispacher

/**
* Example Controller
*
*/
class ExampleController extends AppController
{

/**
 * Index method
 *
 * @return \Cake\Network\Response|null
 */
public function index()
{
    $shell = new ShellDispatcher(); //create object of your Shell Dispatcher
    $output = $shell->run(['cake', 'foo']); //here foo is your shell name

    if (0 === $output) {
        $this->Flash->success('Success from shell command.');
    } else {
        $this->Flash->error('Failure from shell command.');
    }

    return $this->redirect('/');
  }
}
