AIX Version 4.3 System Management Guide: Operating System and Devices

Accounting for BSD 4.3 System Managers

Both the AIX accounting files in the /usr/lib/acct directory and the system activity reporting tools in the /usr/lib/sa directory are identical to those available with AT&T System V Release 4 (SVR4) with the addition of 4.3 BSD accounting utilities.

Many of the accounting commands are in the /usr/lib/acct directory. To begin system accounting, use the /usr/lib/acct/startup command. If accounting is not started, commands such as lastcomm(1) cannot return information.

AIX provides these 4.3 BSD accounting facilities:

last(1) Indicates last logins of users and terminals.
lastcomm (1) Shows in reverse order the last commands executed.
acct(3) Enables and disables process accounting.
ac(8) Login accounting.
accton (8) Turns system accounting on or off.
sa(8) Generally maintains system accounting files.

AIX also provides these System V Interface Definition (SVID) Issue II accounting commands and library functions:

acctcms (1) Produces command usage summaries from accounting records.
acctcom (1) Displays selected process-accounting record summaries.
acctcon1 (1) Converts login/logoff records to session records.
acctcon2 (1) Converts login/logoff records to total accounting records.
acctdisk (1) Generates total accounting records from diskusg(1) command output.
acctmerg (1) Merges total accounting files into an intermediary file.
accton (1) Turns on accounting.
acctprc1 (1) Processes accounting information from acct(3) command.
acctprc2 (1) Processes output of acctprc1(1) command into total accounting records.
acctwtmp (1) Manipulates connect-time accounting records.
chargefee(1) Charges to login name.
ckpacct(1) Checks size of /usr/adm/pacct file.
