Cron jobs are added separately for each user through the cPanel and WHM web interface, namely cPanel “Advanced” -> “Cron Jobs“.
Through the WHM panel “Home” -> “Server Configuration” -> “Configure cPanel Cron Jobs“.
But there are also system tasks that can not be seen through the panel.
They can be seen by connecting through SSH to the server and running the command from the root user:
crontab -e
or from another user via sudo:
sudo crontab -e
In the nano editor, the shortcut Ctrl+X is used to exit, and y/n to save or discard the changes.
The file itself with the tasks is located on the path /var/spool/cron/root
If an annoying report is sent to an e-mail when executing an assignment, you can hide the output of the task by adding the following code to the end of the command:
>/dev/null 2>&1
To restart the Cron service, use the command:
service crond restart
