How to save/redirect output from Laravel 5 Artisan command?

I managed to get this to work using Artisan::output(), which returns the output of the latest command.

Route::get('/test', function()
{    
    Artisan::call('testCommand', array());

    return Artisan::output();
});

should do it for you.

I did this

php artisan your:command >> output.txt

worked fine for me.
