Hi

I have run a script which lists all the cron jobs for all users. I am running AlmaLinux 8.6 with the Plesk Control panel. Most of the cron jobs listed are owned by psaadm - they have been set up by Plesk and i see them in the Plesk scheduler.

But - in addition to this there are scripts in e.g. /etc/cron.daily - which do not appear to be listed when I output all the cron jobs for all users. (this script loops through /etc/passwd and runs crontab -u $user for each user).

Do these scripts in /etc/cron.daily run? I have seen that they may be run by anacron? How could I check? And why are they not listed by the method above?

Thanks.

Anything in /etc is a system cron job. /etc/crontab, /etc/cron.hourly, /etc/cron.weekly, /etc/cron.daily, /etc/cron.mounthly and /etc/cron.d. Typically System Administrators jobs are scheduled there and jobs required by specific daemons like logrotate. User's cron jobs are located in /var/spool/cron

cron basically assumes the computer runs 24/7. If the computer is off when a job is scheduled to run there is no mechanism to automatically make sure it runs at next boot. anacron will run certain jobs if scheduled regardless of when the computer is running. Some distributions will make sure that certain jobs run regardless based on either cron or anacron.

Have you looked at /etc/anacrontab?

They are not listed because those jobs are not run directly by a user in /etc/passwd (they are not a crontab job).
