DESCRIPTION


Accounting software is structured as a set of tools (consisting of
both C programs and shell procedures) that can be used to build
accounting systems. acctsh(8) describes the set of shell procedures
built on top of the C programs.


Connect time accounting is handled by various programs that write
records into /var/adm/wtmpx, as described in utmpx(5). The programs
described in acctcon(8) convert this file into session and charging
records, which are then summarized by acctmerg(8).


Process accounting is performed by the system kernel. Upon
termination of a process, one record per process is written to a file
(normally /var/adm/pacct). The programs in acctprc(8) summarize this
data for charging purposes; acctcms(8) is used to summarize command
usage. Current process data may be examined using acctcom(1).


Process accounting records and connect time accounting records (or
any accounting records in the tacct format described in
acct.h(3HEAD)) can be merged and summarized into total accounting
records by acctmerg (see tacct format in acct.h(3HEAD)). prtacct (see
acctsh(8)) is used to format any or all accounting records.


acctdisk reads lines that contain user ID, login name, and number of
disk blocks and converts them to total accounting records that can be
merged with other accounting records. acctdisk returns an error if
the input file is corrupt or improperly formatted.


acctdusg reads its standard input (usually from find / -print) and
computes disk resource consumption (including indirect blocks) by
login.


accton without arguments turns process accounting off. If filename is
given, it must be the name of an existing file, to which the kernel
appends process accounting records (see acct(2) and acct.h(3HEAD)).


acctwtmp writes a utmpx(5) record to filename. The record contains
the current time and a string of characters that describe the reason.
A record type of ACCOUNTING is assigned (see utmpx(5)) reason must be
a string of 11 or fewer characters, numbers, $, or spaces. For
example, the following are suggestions for use in reboot and shutdown
procedures, respectively:

acctwtmp "acctg on" /var/adm/wtmpx
acctwtmp "acctg off" /var/adm/wtmpx


For each user currently logged on, closewtmp puts a false
DEAD_PROCESS record in the /var/adm/wtmpx file. runacct (see
runacct(8)) uses this false DEAD_PROCESS record so that the connect
accounting procedures can track the time used by users logged on
before runacct was invoked.


For each user currently logged on, runacct uses utmp2wtmp to create
an entry in the file /var/adm/wtmpx, created by runacct. Entries in
/var/adm/wtmpx enable subsequent invocations of runacct to account
for connect times of users currently logged in.

OPTIONS


The following options are supported:

-u filename
Places in filename records consisting of those
filenames for which acctdusg charges no one (a
potential source for finding users trying to avoid
disk charges).


-p filename
Specifies a password file, filename. This option is
not needed if the password file is /etc/passwd.


ENVIRONMENT VARIABLES


If any of the LC_* variables (LC_TYPE, LC_MESSAGES, LC_TIME,
LC_COLLATE, LC_NUMERIC, and LC_MONETARY) (see environ(7)) are not set
in the environment, the operational behavior of acct for each
corresponding locale category is determined by the value of the LANG
environment variable. If LC_ALL is set, its contents are used to
override both the LANG and the other LC_* variables. If none of the
above variables are set in the environment, the "C" (U.S. style)
locale determines how acct behaves.

LC_CTYPE
Determines how acct handles characters. When LC_CTYPE is
set to a valid value, acct can display and handle text
and filenames containing valid characters for that
locale. acct can display and handle Extended Unix Code
(EUC) characters where any character can be 1, 2, or 3
bytes wide. acct can also handle EUC characters of 1, 2,
or more column widths. In the "C" locale, only characters
from ISO 8859-1 are valid.


LC_TIME
Determines how acct handles date and time formats. In the
"C" locale, date and time handling follows the U.S.
rules.


FILES


/etc/passwd
Used for login name to user ID conversions.


/usr/lib/acct
Holds all accounting commands listed in section 8
of this manual.


/var/adm/pacct
Current process accounting file.


/var/adm/wtmpx
History of user access and administration
information.
