如何正确执行cron作业？

I'm trying to run a cron job in my laravel project. I run the following command

* * * * * cd c:/PaginasWeb/intranet php artisan schedule:run >> /dev/null 2>&1

and I miss the error

The system can not find the path specified

But that's the route where my project is located, It's the first time I try to do a cron job, and I do not know if I'm doing wrong. The command is executed from c: /
