Performs process-accounting procedures.
/usr/sbin/acct/acctprc1 [ InFile ]
/usr/sbin/acct/accton [ OutFile ]
The three acctprc commands, acctprc1, acctprc2, and accton, are called by the runacct command to perform process-accounting shell procedures.
The acctprc1 command reads records from standard input that are in the acct format, adds the login names that correspond to user IDs, and then writes an ASCII record to standard output. This record contains the user ID, login name, prime CPU time, nonprime CPU time, the total number of characters transferred (in 1024-byte units), the total number of blocks read and written, and mean memory size (in 64-byte units) for each process.
If specified, the InFile parameter contains a list of login sessions in utmp format, sorted by user ID and login name. If the File parameter is not specified, acctprc1 gets login names from the/etc/passwd password file. The information in the InFile parameter helps distinguish among different login names that share the same user ID.
The acctprc2 command reads (from standard input) the records written by the acctprc1 command, summarizes them by user ID and name, and writes the sorted summaries to standard output as total accounting records.
When the accton command is used without parameters, process accounting is turned off. If you specify the OutFile parameter (an existing file), process accounting is turned on, and the kernel adds records to that file. You must specify the OutFile parameter for process accounting to start. The OutFile parameter is not created by the accton command. The file specified by the OutFile parameter must already exist with the proper group, owner, and permissions. Many shell scripts expect the /var/adm/pacct file.
Access Control: These commands should grant execute (x) access only to members of the adm group.
/usr/sbin/acct/acctprc1 < /var/adm/pacct >out.file
/usr/sbin/acct/acctprc2 < out.file > \ /var/adm/acct/nite/daytacct
The resulting file is a binary total accounting file in tacct format, containing individual records sorted by user ID. The file /var/adm/acct/nite/daytacct is merged with other total accounting records by the acctmerg command to produce the daily summary record in the /var/adm/acct/sum/tacct file.
