.Os
|
|
.Sh NAME
|
|
.Nm periodic.conf
|
|
.Nd periodic job configuration information
|
|
.Sh DESCRIPTION
|
|
The file
|
|
.Nm
|
|
contains a description of how daily, weekly and monthly 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 executed 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
|
|
For an unattended machine, suitable values for
|
|
.Va daily_output ,
|
|
.Va weekly_output ,
|
|
and
|
|
.Va 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 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 executed 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
