NAME    [Toc]    [Back]

       acctdisk, acctdusg - Perform disk-usage accounting

SYNOPSIS    [Toc]    [Back]


       acctdusg [-u file] [-pfile]

OPTIONS    [Toc]    [Back]

       Searches  file  as  the alternate file for login names and
       numbers, instead of searching /etc/passwd.  Writes records
       of file names for which it does not charge into file.

DESCRIPTION    [Toc]    [Back]

       Normally  the  acctdisk  and  acctdusg commands are called
       from the dodisk shell procedure to do disk-usage  accounting.
  The  dodisk shell procedure is invoked when the cron
       daemon       executes        commands        in        the
       /usr/spool/cron/crontabs/[filename]  file.  In  the  usual
       case, the output of the diskusg command is the  redirected
       input  to  the acctdisk command. When a more thorough, but
       slower, version of disk accounting is needed, specify  the
       -o  option  with  the dodisk command. This is not normally
       done  in  the  /usr/spool/cron/crontabs/[filename]   file.
       When  the -o option is used, the acctdusg command replaces
       the diskusg command.

       Normally, the acctdisk command reads  a  temporary  output
       file  produced by the diskusg or the acctdusg command from
       standard input, converts each record into  a  total  diskaccounting
 record, and writes it to standard output. These
       records are merged with other accounting records with  the
       acctmerg command to produce a daily accounting report.

       The  acctdusg command is called when the -o option is used
       with the dodisk command. This produces  a  more  thorough,
       but  slower,  version  of disk-accounting records.  Otherwise,
 the dodisk shell procedure invokes the diskusg  command.

       The  acctdusg  command reads a list of files from standard
       input (usually piped from a find / -print  command),  computes
  the  number  of  disk  blocks  (including  indirect
       blocks) allocated to each file divided by  the  number  of
       hard  links then writes an individual record for each user
       to standard output.

       To find the user who is charged for the file, compare each
       file pathname with the login directories of the users. The
       user who has  the  longest  pathname  component  match  is
       charged  for the file. Therefore, the relevant information
       for charging users is not ownership  of  a  file  but  the
       directory where it is stored.

       The acctdusg command searches the /etc/passwd file, or the
       alternate password file specified with the -p option,  for
       login  names,  numbers  and login directories. Each output
       record has the following format:

       uid login #blocks

EXAMPLES    [Toc]    [Back]

       To start normal disk-accounting  procedures,  add  a  line
       similar       to       the      following      to      the
       /usr/spool/cron/crontabs/[filename]  file:  0  2  *  *   4

              The  foregoing  example  is a typical, periodically
              invoked command that the cron daemon reads and executes.
  The  period is expressed by a 6-field entry
              having the format: mm hh daymon  monyr  wkday  cmd.
              For  any  field requiring digits, numbers are integers.

              These six fields have the  following  significance:
              Purpose  Time variable that has the value 0 through
              59 expressing minutes past the hour.  Time variable
              for  the hour of the day in 24-hour clock notation.
              Time variable for the day of the month.  Time variable
  for month of the year.  Time variable for the
              day or days of the week,  where  0  is  Sunday  and
              inclusive  days  are  separated  with a hyphen (-).
              Command the cron daemon must execute.

              Whenever  you  write  any  of  the  time  variables
              described  in  the  foregoing table, an unspecified
              value must be noted with an * (asterisk) to  define
              an empty field.

              In  the  foregoing example, the dodisk shell procedure
 runs at 02:00 hours (2)  every  Thursday  (4).
              The  dodisk shell procedure calls the acctdusg command
 to redirect its input to a temporary file  and
              then calls the acctdisk shell procedure to redirect
              disk-usage records from the temporary file as input
              to  a /var/adm/acct/nite/[filename] file as output.
              The file stored in the /var/adm/acct/nite subdirectory
  is  a  permanent  binary record of disk usage
              for the specified period.  To  initiate  a  slower,
              more thorough disk-accounting procedure, add a line
              similar     to     the     following     to     the
              /usr/spool/cron/crontabs/[filename]  file.  0 2 * *
              0-4 /usr/sbin/acct/dodisk -o

              The dodisk shell procedure calls the acctdusg  command
  and  the acctdisk command to write disk-usage
              records  to   the/var/adm/acct/nite/[filename] file
              just  as in the previous example. The dodisk procedure
 runs at 2 a.m. every day (0-6) including  Sunday.
