They take care of some basic administrative tasks. Their output, if any, is mailed to root. .Pp .Sy Note : The scripts are all run as part of root's .Xr crontab 5 . However, it is strongly suggested that the root mail account be an alias that forwards messages to a real user or set of users. Otherwise, root's mail will simply accumulate in .Pa /var/mail until the partition holding it runs out of space. See .Xr newaliases 8 for further details. .Pp These scripts should not be altered. Local additions should be made to the files .Pa /etc/daily.local , .Pa /etc/weekly.local , and .Pa /etc/monthly.local , which will be executed by .Pa /etc/daily , .Pa /etc/weekly , and .Pa /etc/monthly , respectively. The .Pa *.local files are executed first, which makes it convenient to do any necessary cleanup and backup and to define any required shell variables before the script is run. .Ss /etc/daily This script is run daily. It currently does the following: .Bl -dash .It Runs the script .Pa /etc/daily.local , if it exists. .It Removes scratch and junk files from .Pa /tmp and .Pa /var/tmp . .It Removes stale files from the .Xr rwhod 8 database. .It Removes system messages older than 21 days for the .Xr msgs 1 utility. .It Purges accounting records from .Pa /var/account , if they exist. See .Xr accton 8 and .Xr sa 8 . .It Creates a backup root file system which is updated daily. This only happens if the following conditions are met: .Bl -enum -offset indent .It The environment variable .Ev ROOTBACKUP must be set. For example, the following can be added to .Pa /etc/daily.local : .Pp .Dl ROOTBACKUP=1 .It The mount directory .Pa /altroot must exist, and there must be an .Pa /etc/fstab entry specifying a configured disk device, the file system type .Sq ffs , and .Sq xx for the mount options, e.g. .Pp .Dl /dev/wd0j /altroot ffs xx 0 0 .El .It Checks disk status. Reports on the amount of disk used/available via .Xr df 1 . Reports on which file systems need to be dumped via .Xr dump 8 . .It Reports on the status of the mail queue via .Xr mailq 8 . .It Reports networking statistics via .Xr netstat 1 . .It Gives an uptime for every machine which exists in .Pa /var/rwho , via the .Xr ruptime 1 utility. .It Runs the .Xr calendar 1 utility unless the environment variable .Ev CALENDAR is set to 0 in .Pa /etc/daily.local or the host is a .Xr yp 8 client. .It If .Ev CHECKFILESYSTEMS is set to 1 in .Pa /etc/daily.local , runs .Xr fsck 8 with the no-write flag .Pq Fl n . .It If the file .Pa /etc/Distfile exists, runs the .Xr rdist 1 utility. .It Runs the system security check script, .Pa /etc/security . See .Xr security 8 for further details. .El .Ss /etc/weekly This script is run weekly. It currently does the following: .Bl -dash .It Runs the script .Pa /etc/weekly.local , if it exists. .It Rebuilds the .Xr locate 1 database, if there is an existing .Pa /var/db/locate.database file. .It Rebuilds the .Xr whatis 1 database(s) via .Xr makewhatis 8 . .It If .Ev LOGINACCOUNTING is set to 1 in .Pa /etc/weekly.local and the .Pa /var/log/wtmp file exists, show individual users' login via the .Xr ac 8 utility. .El .Ss /etc/monthly This script is run monthly. It currently does the following: .Bl -dash .It Runs the script .Pa /etc/monthly.local , if it exists. .El .Sh ENVIRONMENT The following variables can be set in .Pa /etc/daily.local : .Pp .Bl -tag -width "CHECKFILESYSTEMS" -compact .It Ev CALENDAR If set to 1, run .Xr calendar 1 . .It Ev CHECKFILESYSTEMS If set to 1, run .Xr fsck 8 with the no-write flag. .It Ev ROOTBACKUP If set to 1, make a backup of the root file system. .It Ev VERBOSESTATUS If set to 0, .Xr df 1 , .Xr dump 8 , .Xr netstat 1 , and .Xr ruptime 1 are skipped. Consequently, if none of the other commands produce any output, no mail will be sent to root. .El .Pp The following variables can be set in .Pa /etc/weekly.local : .Pp .Bl -tag -width "CHECKFILESYSTEMS" -compact .It Ev LOGINACCOUNTING If set to 1, run .Xr ac 8 to report login accounting. .El .Sh FILES .Bl -tag -width "/var/cron/tabs/root" -compact .It Pa /etc/daily Daily maintenance script. .It Pa /etc/daily.local Site specific daily maintenance script. .It Pa /etc/weekly Weekly maintenance script. .It Pa /etc/weekly.local Site specific weekly maintenance script. .It Pa /etc/monthly Monthly maintenance script. .It Pa /etc/monthly.local Site specific monthly maintenance script. .It Pa /var/cron/tabs/root Root .Xr crontab 5 . .El .Sh SEE ALSO .Xr calendar 1 , .Xr crontab 1 , .Xr df 1 , .Xr locate 1 , .Xr msgs 1 , .Xr netstat 1 , .Xr rdist 1 , .Xr ruptime 1 , .Xr rwho 1 , .Xr whatis 1 , .Xr crontab 5 , .Xr ac 8 , .Xr accton 8 , .Xr cron 8 , .Xr dump 8 , .Xr fsck 8 , .Xr mailq 8 , .Xr makewhatis 8 , .Xr sa 8 , .Xr security 8 , .Xr yp 8 .Sh HISTORY This manual page first appeared in .Ox 3.4 . .Sh CAVEATS If the host machine is not running 24/7, these scripts may never be run. Adjusting the time fields in the system .Xr crontab 5 may partially alleviate this problem. .Pp Be careful when adding local additions. Services such as .Qq www have their own users, and should be run as such, not as root. It may be more appropriate to create a separate .Xr crontab 5 for such services.
