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. .El .Pp The following variables are used by the standard scripts that reside in .Pa /etc/periodic/daily : .Bl -tag -offset 4n -width 2n .It Va daily_clean_disks_enable .Pq Vt bool Set to .Dq Li YES if you want to remove all files matching .Va daily_clean_disks_files daily. .It Va daily_clean_disks_files .Pq Vt str Set to a list of file names to match. Wild cards are permitted. .It Va daily_clean_disks_days .Pq Vt num When .Va daily_clean_disks_enable is set to .Dq Li YES , this must also be set to the number of days old that a file's access and modification times must be before it is deleted. .It Va daily_clean_disks_verbose .Pq Vt bool Set to .Dq Li YES if you want the removed files to be reported in your daily output. .It Va daily_clean_tmps_enable .Pq Vt bool Set to .Dq Li YES if you want to clear temporary directories daily. .It Va daily_clean_tmps_dirs .Pq Vt str Set to the list of directories to clear if .Va daily_clean_tmps_enable is set to .Dq Li YES . .It Va daily_clean_tmps_days .Pq Vt num When .Va daily_clean_tmps_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 is deleted. .It Va daily_clean_tmps_ignore .Pq Vt str Set to the list of files that should not be deleted when .Va daily_clean_tmps_enable is set to .Dq Li YES .

This may not work with MTAs other than .Xr sendmail 8 . .It Va daily_status_security_enable .Pq Vt bool Set to .Dq Li YES if you want to run the security check. The security check is another set of .Xr periodic 8 scripts. The system defaults are in .Pa /etc/periodic/security . Local scripts should be placed in .Pa /usr/local/etc/periodic/security . See the .Xr periodic 8 manual page for more information. .It Va daily_status_security_inline .Pq Vt bool Set to .Dq Li YES if you want the security check output inline.

If the list is empty or not set, all zfs pools are scrubbed. .It Va daily_scrub_zfs_default_threshold .Pq Vt int Number of days between a scrub if no pool-specific threshold is set. If not set, the default value is 35, corresponding to 5 weeks. .It Va daily_scrub_zfs_ Ns Ao Ar poolname Ac Ns Va _threshold .Pq Vt int The same as .Va daily_scrub_zfs_default_threshold but specific to the pool .Ao Ar poolname Ac Ns . .It Va daily_local .Pq Vt str Set to a list of extra scripts that should be run after all other daily scripts.

This script regenerates the database used by the .Xr apropos 1 command. .It Va weekly_catman_enable .Pq Vt bool Set to .Dq Li YES if you want to run .Pa /usr/libexec/catman.local . This script processes all out of date manual pages, speeding up the .Xr man 1 command at the expense of disk space. .It Va weekly_noid_enable .Pq Vt bool Set to .Dq Li YES if you want to locate orphaned files on the system. An orphaned file is one with an invalid owner or group. .It Va weekly_noid_dirs .Pq Vt str A list of directories under which orphaned files are searched for.

Because the dependency tree may be substantially different between versions of .Fx , there may be more than one .Pa INDEX file in .Pa /usr/ports . .Pp Note, if the .Va pkg_version variable is set to .Dq Li portversion , it will also be necessary to arrange that the correct .Pa INDEX file is specified using environment variables and that .Va pkg_version_index is cleared in .Pa /etc/periodic.conf .Pq Dq Li pkg_version_index= . .It Va weekly_local .Pq Vt str Set to a list of extra scripts that should be run after all other weekly scripts.

Those scripts are usually run from daily .Pq Va daily_status_security_enable , weekly .Pq Va weekly_status_security_enable , and monthly .Pq Va monthly_status_security_enable periodic hooks. The .Va ..._period of each script can be configured as .Dq daily , .Dq weekly , .Dq monthly or .Dq NO . Note that when periodic security scripts are run from .Xr crontab 5 , they will be always run unless their .Va ..._enable or .Va ..._period variable is set to .Dq NO . .Bl -tag -offset 4n -width 2n .It Va security_status_diff_flags .Pq Vt str Set to the arguments to pass to the .Xr diff 1 utility when generating differences. The default is .Fl b u . .It Va security_status_chksetuid_enable .Pq Vt bool Set to .Dq Li YES to compare the modes and modification times of setuid executables with the previous day's values. .It Va security_status_chksetuid_period .Pq Vt str Set to either .Dq Li daily , .Dq Li weekly , .Dq Li monthly or .Dq Li NO . .It Va security_status_chkportsum_enable .Pq Vt bool Set to .Dq Li YES to verify checksums of all installed packages against the known checksums in .Pa /var/db/pkg . .It Va security_status_chkportsum_period .Pq Vt str Set to either .Dq Li daily , .Dq Li weekly , .Dq Li monthly or .Dq Li NO . .It Va security_status_neggrpperm_enable .Pq Vt bool Set to .Dq Li YES to check for files where the group of a file has less permissions than the world at large.
