    you may have to prefix your commands with `exec`_. Please read
    `Symfony Issue#5759`_ to understand why this is happening.

 Disabling Output
 ----------------

 .. versionadded:: 2.5
    The :method:`Symfony\\Component\\Process\\Process::disableOutput` and
    :method:`Symfony\\Component\\Process\\Process::enableOutput` methods were
    introduced in Symfony 2.5.

 As standard output and error output are always fetched from the underlying process,
 it might be convenient to disable output in some cases to save memory.
 Use :method:`Symfony\\Component\\Process\\Process::disableOutput` and
 :method:`Symfony\\Component\\Process\\Process::enableOutput` to toggle this feature::

    use Symfony\Component\Process\Process;

    $process = new Process('/usr/bin/php worker.php');
    $process->disableOutput();
    $process->run();

 .. caution::

    You can not enable or disable the output while the process is running.

    If you disable the output, you cannot access ``getOutput``,
    ``getIncrementalOutput``, ``getErrorOutput`` or ``getIncrementalErrorOutput``.
    Moreover, you could not pass a callback to the ``start``, ``run`` or ``mustRun``
    methods or use ``setIdleTimeout``.
