Laravel计划的任务不是与Cron一起运行，而是与工匠合作

I have created scheduled task and it's running smoothley with command:

php artisan schedule:run

Also I'm able to run it with command:

php /var/www/my.app/artisan schedule:run >> /dev/null 2>&1

But when I try to run

* * * * * php /var/www/my.app/artisan schedule:run >> /dev/null 2>&1

as it described in Laravel doc's here: https://laravel.com/docs/5.5/scheduling - nothing happends. If I remove

>> /dev/null 2>&1

(which is here to hide output). I'm getting:

Command not found

Thanks for any help.

Just in case I used this command to add line to cron:

(crontab -l ; echo "* * * * * php /var/www/bmon.app/artisan schedule:run >> /dev/null 2>&1")| crontab -

Add this line in your cron:

* * * * * php /var/www/my.app/artisan schedule:run >> /dev/null 2>&1
