4.8 EASYCRON - Time-based Job Scheduling

This package was inititated by Stefan Manske email: fli4l@stephan.manske-net.de and adapted to version 2.1 by the fli4l-team.

4.8.1 Configuration

By using OPT_EASYCRON it is possible to execute commands at designated times by adding them to the config-file.

The following entries are supported:

OPT_EASYCRON

OPT_EASYCRON='yes' activates the package

Default setting: OPT_EASYCRON='no'

EASYCRON_MAIL

Avoid the sending of unwanted mails by crond.

Default setting: EASYCRON_MAIL='no'

EASYCRON_N

The number of commands to be executed by cron.

EASYCRON_x_CUSTOM

Those familiar with the settings in crontab may define additional settings for each entry (like MAILTO, PATH...). Entries have to be separated by \\. You should be really familiar with cron to use this option.

Default setting: EASYCRON_CUSTOM=''

EASYCRON_x_COMMAND

Specify the command to be executed in EASYCRON_x_COMMAND, for example:

        EASYCRON_1_COMMAND='echo 1 '>' /dev/console'

EASYCRON_x_TIME

specifies execution times according to the cron syntax.

4.8.2 Examples

The computer outputs ``Happy new year!'' to the console

        EASYCRON_1_COMMAND = 'echo Happy new year! > /dev/console'
        EASYCRON_1_TIME    = '0 0 31 12 *'

xxx will be executed Monday to Friday from 7AM to 8PM Uhr every full hour.

        EASYCRON_1_COMMAND = 'xxx'
        EASYCRON_1_TIME    = '0 7-20 0 * 1-5'

The router terminates the DSL internet connection each night at 03:40AM and reestablishes it after 5 seconds. Device names to be used: pppoe, ippp[1-9], ppp[1-9].
