NAME
acct: acctdisk, acctdusg, accton, acctwtmp closewtmp, utmp2wtmp -
overview of accounting and miscellaneous accounting commands
SYNOPSIS
/usr/lib/acct/acctdisk
/usr/lib/acct/acctdusg [-u file] [-p file]
/usr/lib/acct/accton [file]
/usr/lib/acct/acctwtmp "reason"
/usr/lib/acct/closewtmp
/usr/lib/acct/utmp2wtmp
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/wtmp, as described in utmp(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 Reliant UNIX 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 com-
mand usage. Current process data may be examined using acctcom(1).
Process accounting and connect time accounting (or any accounting
records in binary format) can be merged and summarized into total
accounting records by acctmerg. 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.
acctdusg reads its standard input (usually from find / -print) and
computes disk resource consumption (including indirect blocks) by
login. If -u is given, records consisting of those filenames for which
acctdusg charges no one are placed in file (a potential source for
finding users trying to avoid disk charges). If -p is given, file is
the name of the password file. This option is not needed if the pass-
word file is /etc/passwd.

accton alone turns process accounting off. If file is given, process
accounting is turned on and the kernel process accounting records to
file [see acct(2) and acct(4)].
acctwtmp writes a utmp(4) record to its standard output. The record
contains the current time and a string of characters that describe the
reason. A record type of ACCOUNTING is assigned [see utmp(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 shut-
down procedures, respectively:
acctwtmp "acctg on" >> /var/adm/wtmp
acctwtmp "acctg off" >> /var/adm/wtmp
For each user currently logged on, closewtmp puts a false DEADPROCESS
record in the /var/adm/wtmp file. runacct [see runacct(1M)] uses this
false DEADPROCESS 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/wtmp, created by runacct. Entries in
/var/adm/wtmp enable subsequent invocations of runacct to account for
connect times of users currently logged in.
