cron - 3.0pl1-137pureos1 main

The cron daemon is a background process that runs particular programs at
particular times (for example, every minute, day, week, or month), as
specified in a crontab. By default, users may also create crontabs of
their own so that processes are run on their behalf.
.
Output from the commands is usually mailed to the system administrator
(or to the user in question); you should probably install a mail system
as well so that you can receive these messages.
.
This cron package does not provide any system maintenance tasks. Basic
periodic maintenance tasks are provided by other packages, such
as checksecurity.
