##############
Task Scheduler
##############
The task scheduler allows you to execute tasks on a given schedule. It makes
use of UNIX cron_.
.. note:: All scripts excecuted this way are executed as root user - this may
be dangerous. Together with :ref:`command-scripting` this can be used for
automating (re-)configuration.
.. cfgcmd:: set system task-scheduler task <task> interval <interval>
Specify the time interval when `<task>` should be executed. The interval
is specified as number with one of the following suffixes:
* ``none`` - Execution interval in minutes
* ``m`` - Execution interval in minutes
* ``h`` - Execution interval in hours
* ``d`` - Execution interval in days
.. note:: If suffix is omitted, minutes are implied.
.. cfgcmd:: set system task-scheduler task <task> crontab-spec <spec>
Set execution time in common cron_ time format. A cron `<spec>` of
``30 */6 * * *`` would execute the `<task>` at minute 30 past every 6th hour.
.. cfgcmd:: set system task-scheduler task <task> executable path <path>
Specify absolute `<path>` to script which will be run when `<task>` is
executed.
.. cfgcmd:: set system task-scheduler task <task> executable arguments <args>
Arguments which will be passed to the executable.
