I have created some commands and scheduled them to work periodically. A few months later I noticed that there is no cron job running but commands run without problem.
In the documentation, it says that I need to set a cron job in the operating system for scheduled commands to run. I couldn't find any. But artisan
Basically, when a cron job is created, the associated crontab file is generated for each user that ran the actual command. When this particular artisan cron was generated, it was created by the
www-data user, which was why you couldn't find it as easily.
Each crontab is stored as
/var/spool/cron/crontabs/<username>, and should be open to something like Grep, or other commands to inspect their contents.
Once you find the correct crontab that needs to be adjusted, you can change the file by running
sudo crontab -e -u <username>.
