php app / console stops working

After a slight modification of my units, I wanted the update with a simple php app/console doctrine: update --force. But no action executed and in addition no response. I then did a php app/check.php meaning me no problems (Your system is ready to run Symfony2 projects). I do not understand and it doesn't provide an error. Here's what I've done:

Command: ********: ***** ProjetSymphony $ php app / console***
Answer (none): ******* **** $ ProjetSymphony***

If someone has an idea.
