vyatta-cron

Vyatta cron configuration templates and scripts

Depends on cron package (installed by default).

Configuration commands:

system
    task-scheduler
        task <name>
            crontab-spec <UNIX cron time spec>
            executable
                arguments <arguments string>
                path <path to executable>
            interval
                <int32>[mhd]    

Example:

system
    task-scheduler
        task mytask
            executable
                path /config/scripts/mytask
                arguments "arg1 arg2 arg3"
        task anothertask
            crontab-spec "* * * 1 *"
            executable
                path /config/scripts/anothertask

interval

set system task-scheduler task <name> interval <value><suffix>

Sets the task to execute every N minutes, hours, or days. Suffixes:

• m -- minutes
• h -- hours
• d -- days

If suffix is omitted, minutes are implied.

Examples:

Run every five minutes:

set system task-schedule task TEST interval 5

or

set system task-schedule task TEST interval 5m

Run every two hours:

set system task-schedule task TEST interval 2h

Run every 7 days:

set system task-schedule task TEST interval 7d

cron-spec

This is usual UNIX cron time spec. For the cases "interval" is not enough.

set system task-scheduler task TEST crontab-spec "* * * 1 *"

executable

Path and arguments of the executable to run.

set system task-schedule task TEST executable path /config/scripts/myscript
set system task-schedule task TEST executable arguments "arg1 arg2"

Technical details

This package is just a wrapper for UNIX crontab, nothing more.

Configuration is written to /etc/cron.d/vyatta-crontab.

On reboot it is removed before config load and re-created if related configuration exists.
