brian 4484d23ba7 Another overhaul of the periodic stuff. 
All periodic sub-scripts <larf> now have their return codes interpreted
by periodic(8).  Output may be masked based on variable values in
periodic.conf.

It's also now possible to email periodic output to arbitrary addresses,
or to send it to a log file, examples of which can be found in
newsyslog.conf.

The upshot of it all should be no discernable changes to the default
behaviour of periodic(8).

.Sh NAME
.Nm periodic.conf
.Nd periodic job configuration information.
.Sh DESCRIPTION
The file
.Nm periodic.conf
contains a description of how daily, weekly and montly system maintenance
jobs should run.
It resides in the
.Pa /etc/defaults
directory and parts may be overridden by a file of the same name in
.Pa /etc ,
which itself may be overridden by the
.Pa /etc/periodic.conf.local
file.
.Pp
.Nm
is actually sourced as a shell script from each of the periodic scripts
and is intended to simply provide default configuration variables.
.Pp
The following variables are used by
.Xr periodic 8
itself:
.Bl -tag -offset 4n -width 2n
.It Ar local_periodic
(str) List of directories to search for periodic scripts.
This list is always prefixed with
.Pa /etc/periodic ,
and is only used when an argument to
.Xr periodic 8
is not an absolute directory name.
.It Ar dir Ns No _output
(path or list) What to do with the output of the scripts envoked from
the directory
.Ar dir .
If this variable is set to an absolute path name, output is logged to
that file, otherwise it is taken as one or more space seperated email
addresses and mailed to those users.
If this variable is not set, it defaults to
.Dq root .
.Pp
For an unattended machine, suitable values for
.Ar $daily_output ,
.Ar $weekly_output ,
and
.Ar $monthly_output
might be
.Dq /var/log/daily.log ,
.Dq /var/log/weekly.log ,
and
.Dq /var/log/monthly.log
respectively, as
.Xr newsyslog 8
will rotate these files (if they exists) at the appropriate times.
.It Ar dir Ns No _show_success
.It Ar dir Ns No _show_info
.It Ar dir Ns No _show_badconfig
(bool) These variables control whether
.Xr periodic 8
will mask the output of the envoked scripts based on their return code
(where
.Ar dir
is the base directory name in which each script resides).
If the return code of a script is
.Sq 0
and
.Ar dir Ns No _show_success is set to
.Dq NO ,
.Xr periodic 8
will mask the script's output.
If the return code of a script is
.Sq 1
and
.Ar dir Ns No _show_info is set to
.Dq NO ,
.Xr periodic 8
will mask the script's output.
If the return code of a script is
.Sq 2
and
.Ar dir Ns No _show_badconfig is set to
.Dq NO ,
.Xr periodic 8
will mask the script's output.
If these variables are set to neither
.Dq YES
nor
.Dq NO ,
the default to
.Dq YES ,
.Dq YES
and
.Dq NO
respectively.
.Pp
Refer to the
.Xr periodic 8
man page for how script return codes are interpreted.
