I'm have a laravel5.5 project up on shared hosting and trying to run cron job to execute the command "schedule:run" but it just won't execute I think I'm writing the command wrong:

```
/usr/local/bin/php home/schoolco/prototype/artisan schedule:run >> /dev/null 2>&1

```

where prototype in the name of my laravel project. 
the command works in this directory using ssh. 
please if you have any observation or thought share it.
