 print $process->getOutput();
 echo $process->getOutput();

 The component takes care of the subtle differences between the different platforms
 when executing the command.
 :method:`Symfony\\Component\\Process\\Process::clearErrorOutput` clears
 the contents of the error output.

 .. versionadded:: 2.5
    The ``mustRun()`` method was introduced in Symfony 2.5.

 The ``mustRun()`` method is identical to ``run()``, except that it will throw
 a :class:`Symfony\\Component\\Process\\Exception\\ProcessFailedException`
 if the process couldn't be executed successfully (i.e. the process exited
 with a non-zero code)::

    use Symfony\Component\Process\Exception\ProcessFailedException;
    use Symfony\Component\Process\Process;

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

    try {
        $process->mustRun();

        echo $process->getOutput();
    } catch (ProcessFailedException $e) {
        echo $e->getMessage();
    }

 Getting real-time Process Output
 --------------------------------

 .. versionadded:: 2.4
   The :method:`Symfony\\Component\\Process\\Process::setIdleTimeout` method
   was introduced in Symfony 2.4.


 In contrast to the timeout of the previous paragraph, the idle timeout only
 considers the time since the last output was produced by the process::

   use Symfony\Component\Process\Process;


   $process = new Process('something-with-variable-runtime');
   $process->setTimeout(3600);
   $process->setIdleTimeout(60);
   $process->run();


 In the case above, a process is considered timed out, when either the total runtime
 exceeds 3600 seconds, or the process does not produce any output for 60 seconds.
