DESCRIPTION

Crontab is the program used to let users install, deinstall or list recurrent jobs in the legacy cron format.
Each user can have their own crontab, and though these are files in /var/spool/cron/crontabs, they are not intended to be edited directly.
These jobs are then automatically translated in systemd Timers & Units by systemd-crontab-generator.

FILES

Directory for users crontabs.

/etc/cron.allow

/etc/cron.deny

list of users that aren’t allowed to use crontab
(by default, only root can use crontab)

LIMITATIONS

SELinux is not supported.
Some extra settings can only be tweaked with

systemctl edit cron-<schedule>.[timer|service]
see systemd.cron(7) for more details.
