Scheduled tasks

Anacron jobs

  • Files under /etc/cron.xyz (i. e. daily) dirs.
  • These files have to be executable, owned by root, not writable by group or other.
  • Symlinks have to point to files owned by root.
  • File names must be made up of letters, digits, underscores or hyphens only.

Test (manually run) scripts.

sudo run-parts /etc/cron.daily
  • Tested on Fedora 29.

Logging cron jobs

Redirect STDOUT and STDERR to a file.

* * * * * myjob.sh >> /var/log/myjob.log 2>&1
  • Whether cron tried to execute the job is stored in /var/log/syslog or /var/log/cron.log.
