 .Dt PERIODIC.CONF 5
 .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
 The
 .Nm
 file
 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 Ao Ar dir Ac Ns Va _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 Li /var/log/daily.log ,
 .Dq Li /var/log/weekly.log ,
 and
 .Dq Li /var/log/monthly.log
 respectively, as
 .Xr newsyslog 8
 will rotate these files (if they exists) at the appropriate times.
 .It Ao Ar dir Ac Ns Va _show_success
 .It Ao Ar dir Ac Ns Va _show_info
 .It Ao Ar dir Ac Ns Va _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
 .Ao Ar dir Ac Ns Va _show_success
 is set to
 .Dq Li NO ,
 .Xr periodic 8
 will mask the script's output.
 If the return code of a script is
 .Sq 1
 and
 .Ao Ar dir Ac Ns Va _show_info
 is set to
 .Dq Li NO ,
 .Xr periodic 8
 will mask the script's output.
 If the return code of a script is
 .Sq 2
 and
 .Ao Ar dir Ac Ns Va _show_badconfig
 is set to
 .Dq Li NO ,
 .Xr periodic 8
 will mask the script's output.
 If these variables are set to neither
 .Dq Li YES
 nor
 .Dq Li NO ,
 they default to
 .Dq Li YES ,
 .Dq Li YES
 and
 .Dq Li NO
 respectively.
 .Pp
 Refer to the
 .Xr periodic 8
 manual page for how script return codes are interpreted.
 .It Va anticongestion_sleeptime
 .Pq Vt int
 The maximum number of seconds to randomly sleep in order to smooth bursty loads
 on a shared resource, such as a download mirror.

 weekly
 .Pq Va weekly_status_security_enable ,
 and monthly
 .Pq Va monthly_status_security_enable

 # This is defaults/periodic.conf - a file full of useful variables that
 # you can set to change the default behaviour of periodic jobs on your
 # system.  You should not edit this file!  Put any overrides into one of the
 # $periodic_conf_files instead and you will be able to update these defaults
 # later without spamming your local configuration information.
 #
 # The $periodic_conf_files files should only contain values which override
 # values set in this file.  This eases the upgrade path when defaults
 # are changed and new features are added.
 #
 # For a more detailed explanation of all the periodic.conf variables, please
 # refer to the periodic.conf(5) manual page.
