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.
This script is run daily. It currently does the following:
ROOTBACKUP
must be
set. For example, the following can be added to
/etc/daily.local:
ROOTBACKUP=1
/dev/wd0j /altroot ffs xx 0
0
CALENDAR
is set to 0 in /etc/daily.local or the host is a
yp(8) client.CHECKFILESYSTEMS
is set to 1 in
/etc/daily.local, runs
fsck(8) with the no-write
flag (-n
).This script is run weekly. It currently does the following:
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.This script is run monthly. It currently does the following:
The following variables can be set in /etc/daily.local:
CALENDAR
CHECKFILESYSTEMS
ROOTBACKUP
VERBOSESTATUS
The following variables can be set in /etc/weekly.local:
LOGINACCOUNTING
MAKEWHATISARGS
calendar(1), crontab(1), df(1), locate(1), netstat(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)
The daily
, weekly
,
and monthly
scripts first appeared in
4.3BSD-Reno. This manual page first appeared in
OpenBSD 3.4.
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.
