 .. note::

    The :method:`Symfony\\Component\\Process\\Process::wait` method is blocking,
    which means that your code will halt at this line until the external
    process is completed.

 :method:`Symfony\\Component\\Process\\Process::wait` takes one optional argument:
 a callback that is called repeatedly whilst the process is still running, passing
 in the output and its type::

    $process = new Process('ls -lsa');
    $process->start();

    $process->wait(function ($type, $buffer) {
        if (Process::ERR === $type) {
            echo 'ERR > '.$buffer;
        }
    });
