acctmerg Command

Purpose

Merges total accounting files into an intermediary file or a daily report.

Syntax

/usr/sbin/acct/acctmerg [  -a [ Specification ] ] [  -h [ Specification ] ] [  -i [ Specification ] ] [  -p [ Specification ] ] [  -q Filename ] [  -v [ Specification ] ] [ -X ] [  -t ] [  -u ] [ File ... ]

Description

The acctmerg command merges process, connect-time, fee, disk-usage, and queuing (printer) total accounting records (in tacct binary or tacct ASCII format, tacctx binary, or tacctx ASCII format) and then writes the results to standard output. (See the tacct structure in the acct File Format for a description of the total accounting format or /usr/include/sys/tacct.h for a description of the tacctx format). The acctmerg command reads the total accounting records from standard input and from the additional files (up to nine) specified by the File parameter. The acctmerg command then merges the records by identical keys, usually a user ID and name. To facilitate storage, the acctmerg command writes the output in binary format unless you use either the -a, -v, or -p flag.

The acctmerg command is called by the runacct command to produce either an intermediate report when one of the input files is full, or to merge the intermediate reports into a cumulative total. The intermediate report is stored in the /var/adm/acct/nite(x)/daytacct file. The cumulative report is stored in the /var/adm/acct/sum(x)/tacct file. The cumulative total is the source from which the monacct command produces the ASCII-format monthly summary report. The monthly summary report is stored in the /var/adm/acct/fiscal file.

The Specification variable allows you to select input or output fields, as illustrated in Example 1. A field specification is a comma-separated list of field numbers, in the order specified in the tacct(x) structure in the acct File Format. Field ranges may be used, with array sizes taken into account, except for the ta_name characters. In the following example:

-h2-3,11,15-13,2

The -h flag causes column headings to display for the following types of data, in this order:

• login name (2)
• prime CPU (3)
• connect time (11)
• fee (15)
• queuing system (14, as implied in the range)
• disk usage data (13)
• the login name again (2)

The default displays all fields, otherwise specified as 1-18 or 1-, and produces wide output lines containing all the available accounting data.

Queueing system, disk usage, or fee data can be converted into tacct records by using the acctmerg -i Specification command.

The tacct fields are:

Examples

1. To merge disk accounting file dacct with field specification -i1-2,13,18 into an existing total accounting file, tacct, enter:

   acctmerg -i1-2,13,18 <dacct | acctmerg tacct >output

   The acctmerg command reads the field specifications for the user ID, login name, number of blocks, and number of disk samples (i1-2,13,18) from the dacct file, merges this information with a tacct record, and writes the result to standard output.
2. To make repairs to the tacct format file jan2.rpt, first enter:

   acctmerg  -v <Jan.2.rpt >jan2.tmp

   Now edit the file jan2.tmp as desired. This command redirects the content of Jan2.rpt to Jan2.tmp, with the output in ASCII format.
3. To redirect Jan2.tmp to Jan2.rpt, with the output in binary record format, enter the following command:

   acctmerg  -i <jan2.tmp >jan2.rpt
