OpenSuSE: location of cron jobs

Posted by jpluimers on 2020/01/20

When you look at how to find listed cron jobs, usually the answer is cron -l or cron -u username -l.

However, on OpenSuSE systems, cron jobs can be in different places, and the sysconfig settings have influence on them too.

These files and directories all influence cron:





Most are available for other Linux distributions as well, but each one might have slightly different configurations (especially for the directories). Some background reading:

Some details:

  • The crontab -l will only list what is in /etc/crontab.
  • These directories are influenced by/etc/sysconfig/cron, especially the DAILY_TIME variable (see below) for the daily jobs.
    All of the directories are checked every 15 minutes through /usr/lib/cron/run-crons:/etc/cron.daily/
  • That script then uses these files for checking when to run:/var/spool/cron/lastrun/cron.weekly

The DAILY_TIME variable:

## Type: string
## Default: ""
# At which time cron.daily should start. Default is 15 minutes after booting
# the system. Example setting would be "14:00".
# Due to the fact that cron script runs only every 15 minutes,
# it will only run on xx:00, xx:15, xx:30, xx:45, not at the accurate time
# you set.
