Crontab contents

The commands listed in /etc/crontab are:

  • Commands executed daily through anacron, stored in /etc/cron.daily
  • Weekly commands in /etc/cron.weekly
  • There are currently no monthly commands
  • The Backupscript, which is executed daily, but is not in /etc/cron.daily
  • A direct call to the reboot command, executed weekly
  • Scripts used by the Fedora media management application, which is probably used by the Key to Nature project (see documentation here: http://biowikifarm.net/meta/Definition_specs_for_Fedora_Ingestion_Service)

Testing the cron scripts

/etc/crontab can be tested using the run-parts command

To list the commands that would have been run daily:

run-parts --list /etc/cron.daily

To test (without executing them) the commands that would have been run daily:

run-parts --test /etc/cron.daily

To run the commands that would have been run daily, with verbose output:

run-parts -v /etc/cron.daily

Weekly and Monthly commands can be tested the same way.

Testing other scripts called in crontab

Backupscripts other commands not in /etc/cron.xxx have to be tested by hand. Please make sure that you are using the corresponding user account and have set any environment variables required.
