.Sh NAME
.Nm periodic.conf
.Nd periodic job configuration information
.Sh DESCRIPTION
The file
.Nm
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 Va local_periodic
.Pq Vt 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 Va dir Ns No _output
.Pq Vt path No or Vt 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 separated email
addresses and mailed to those users.
If this variable is not set or is empty, output is sent to standard output.
.Pp
.It Va dir Ns No _show_success
.It Va dir Ns No _show_info
.It Va dir Ns No _show_badconfig
.Pq Vt 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
.Va 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
.Va 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
.Va 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 ,
they 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.
.El
.Pp
The following variables are used by the standard scripts that reside in
.Bl -tag -offset 4n -width 2n
.Pa /etc/periodic/daily :
.It Va daily_clean_logs_enable
.Pq Vt bool
Set to
.Dq YES
if you want to clear log directories daily.
.It Va daily_clean_logs_dirs
.Pq Vt str
Set to the list of directories to clear if
.Va daily_clean_logs_enable
is set to
.Dq YES .
.It Va daily_clean_logs_days
.Pq Vt num
When
.Va daily_clean_logs_enable
is set, this must also be set to the number of days old that a file's access
and modification times must be before it's deleted.
.It Va daily_clean_logs_ignore
.Pq Vt str
Set to the list of files that should not be deleted when
.Va daily_clean_logs_enable
is set to
.Dq YES .
Wild card characters are permitted.
.It Va daily_clean_logs_verbose
.Pq Vt bool
Set to
.Dq YES
if you want the removed files to be reported in your daily output.
.Sh FILES
.Bl -tag -width /etc/defaults/periodic.conf
.It Pa /etc/defaults/periodic.conf
The default configuration file.
This file contains all default variables and values.
.It Pa /etc/periodic.conf
The usual system specific variable override file.
.It Pa /etc/periodic.conf.local
