cron Documentation


management of regular background processing
cron is a background process (`daemon') that runs programs at regular
intervals (for example, every minute, day, week or month); which
processes are run and at what times are specified in the `crontab'.
Users may also install crontabs so that processes are run on
their behalf, though this feature can be disabled or restricted to
particular users.
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 is configured by default to do various standard
system maintenance tasks, such as ensuring that logfiles do not
grow endlessly and overflow the disk.
The lockfile-progs package is only a "Suggests" because of the poor
way that dselect handles "Recommends", but I do strongly suggest that
you install it; it prevents /etc/cron.daily/standard from running multiple
times if something gets jammed.
