DAILY(8) FreeBSD System Manager's Manual DAILY(8) NAME daily, weekly, monthly - periodic system maintenance DESCRIPTION The three files /etc/daily, /etc/weekly, and /etc/monthly are shell scripts run on a periodic basis by the clock daemon, cron(8). They take care of some basic administrative tasks. Their output, if any, is mailed to root. Note: The scripts are all run as part of root's 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 /var/mail until the partition holding it runs out of space. See newaliases(8) for further details. These scripts should not be altered. Local additions should be made to the files /etc/daily.local, /etc/weekly.local, and /etc/monthly.local, which will be executed by /etc/daily, /etc/weekly, and /etc/monthly, respectively. The *.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. /etc/daily This script is run daily. It currently does the following: - Runs the script /etc/daily.local, if it exists. - Removes scratch and junk files from /tmp. - Purges accounting records from /var/account, if they exist. Processes that were killed due to pledge or memory access violations, or had file access prevented by unveil, are reported in the daily mail. See accton(8), lastcomm(1), and sa(8). - Creates a backup root file system which is updated daily. This only happens if the following conditions are met: 1. The environment variable ROOTBACKUP must be set. For example, the following can be added to /etc/daily.local: ROOTBACKUP=1 2. The mount directory /altroot must exist, and there must be an /etc/fstab entry specifying a configured disk device, the file system type `ffs', and `xx' for the mount options, e.g. /dev/wd0j /altroot ffs xx 0 0 - Checks daemon status. Lists any daemons which are enabled in rc.conf.local(8) but which are not actually running. - Reports on which file systems need to be dumped via dump(8). - Runs the calendar(1) utility unless the environment variable CALENDAR is set to 0 in /etc/daily.local or the host is a yp(8) client. - If CHECKFILESYSTEMS is set to 1 in /etc/daily.local, runs fsck(8) with the no-write flag (-n). - If the file /etc/Distfile exists, runs the rdist(1) utility. - Runs the system security(8) check script. /etc/weekly This script is run weekly. It currently does the following: - Runs the script /etc/weekly.local, if it exists. - Rebuilds the locate(1) database, if there is an existing /var/db/locate.database file. - Rebuilds the whatis(1) database(s) via makewhatis(8). - If LOGINACCOUNTING is set to 1 in /etc/weekly.local and the /var/log/wtmp file exists, show individual users' login via the ac(8) utility. /etc/monthly This script is run monthly. It currently does the following: - Runs the script /etc/monthly.local, if it exists. ENVIRONMENT The following variables can be set in /etc/daily.local: CALENDAR If set to 0, do not run calendar(1). CHECKFILESYSTEMS If set to 1, run fsck(8) with the no-write flag. ROOTBACKUP If set to 1, make a backup of the root file system. The following variables can be set in /etc/weekly.local: LOGINACCOUNTING If set to 1, run ac(8) to report login accounting. MAKEWHATISARGS Arguments for makewhatis(8); empty by default. FILES /etc/daily Daily maintenance script. /etc/daily.local Site specific daily maintenance script. /etc/weekly Weekly maintenance script. /etc/weekly.local Site specific weekly maintenance script. /etc/monthly Monthly maintenance script. /etc/monthly.local Site specific monthly maintenance script. /var/cron/tabs/root Root crontab(5). SEE ALSO calendar(1), crontab(1), locate(1), rdist(1), whatis(1), crontab(5), ac(8), accton(8), cron(8), dump(8), fsck(8), makewhatis(8), sa(8), security(8), yp(8) HISTORY The daily, weekly, and monthly scripts first appeared in 4.3BSD-Reno. This manual page first appeared in OpenBSD 3.4. CAVEATS If the host machine is not running 24/7, these scripts may never be run. Adjusting the time fields in the system crontab(5) may partially alleviate this problem. Be careful when adding local additions. Services such as "www" have their own users, and should be run as such, not as root. It may be more appropriate to create a separate crontab(5) for such services.
