DAILY(8)

NAME    [Toc]    [Back]

     daily, weekly, monthly - periodic system maintenance

SYNOPSIS    [Toc]    [Back]

     /etc/daily
     /etc/weekly
     /etc/monthly

DESCRIPTION    [Toc]    [Back]

     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.   The  results  are
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 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 and /var/tmp.

     -   Removes stale files from the rwhod(8) database.

     -   Checks for core dumps.

     -   Removes system messages older than 21 days for  the  msgs(1) utility.

     -   Purges accounting records from /var/account, if they exist.  See
         accton(8) and sa(8).

     -   Creates a backup root file system which is updated  daily.  This only
         happens if the following conditions are met:

               1.    ROOTBACKUP  must  be set to 1.  It should be
added to root's
                    crontab(5):

                          ROOTBACKUP=1

               2.   The mount directory /altroot must exist,  and
there must be
                    an  /etc/fstab  entry specifying `xx' for the
mount options,
                    e.g.

                          /dev/wd0j /altroot ffs xx 0 0

     -   Checks disk status.   Reports  on  the  amount  of  disk
used/available via
         df(1).   Reports on which file systems need to be dumped
via dump(8).

     -   Reports on the status of the mail queue via mailq(8).

     -   Reports networking statistics via netstat(1).

     -   Gives an  uptime  for  every  machine  which  exists  in
/var/rwho, via the
         ruptime(1) utility.

     -    Runs  the  calendar(1)  utility  unless the environment
variable CALENDAR
         is set to 0 in root's crontab(5) or the host is a  yp(8)
client.

     -    If CHECKFILESYSTEMS is set to 1 in root's crontab, runs
fsck(8) with
         the no-write flag (-n).

     -   If the file  /etc/Distfile  exists,  runs  the  rdist(1)
utility.

     -    Runs  the  system security check script, /etc/security.
See
         security(8) for further details.

   /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).

   /etc/monthly
     This script is run monthly.  It currently does  the  following:

     -   Runs the script /etc/monthly.local, if it exists.

ENVIRONMENT    [Toc]    [Back]

     CALENDAR          Determines whether to run calendar(1).

no-write
                       flag.
     ROOTBACKUP        Determines whether to make a backup of the
root file
                       system.

HISTORY    [Toc]    [Back]

     This manual page first appeared in OpenBSD 3.4.

CAVEATS    [Toc]    [Back]

     If the host machine is not running 24/7, these  scripts  may
never be run.
     The  `@reboot'  field  in 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.
