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(1M) 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(4). The programs described in
acctcon(1M) convert this file into session and charging records, which
are then summarized by acctmerg(1M).


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(1M) summarize this data for
charging purposes; acctcms(1M) 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(1M)) 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(4) 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(4)) 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(1M)) 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(5)) 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 sub-class 1M of
this manual.


/var/adm/pacct
Current process accounting file.


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