acctmerg - Merges total-accounting files into an intermediary
file or a daily accounting file
acctmerg [-ahipv] [specification] [-tu] [file...]
Produces output as ASCII records. Lists column headings.
This option implies -a but is effective with the -p or -v
options. Expects input files to have ASCII records that
are converted to binary output records. Lists input but
without processing. Produces a single record that contains
the totals of all input. Summarizes by user ID
rather than by user name. This is convenient when a single
user ID is allocated to more than one user name. Produces
output in ASCII, with more precise notation for floatingpoint
The acctmerg command combines process, connect time, fee,
disk usage, and queuing (printer) total-accounting records
in tacct binary or tacct ASCII format (see the tacct
structure in the acct.h file format for a description of
this total-accounting format). The acctmerg command writes
the results of record processing to standard output. The
accounting file produced by the acctmerg command may have
entries for as many as 18 columns. Column headings are
printed only when you use the -h option. The following
table lists the column headings by number, the column
heading by label, and the purpose of the entry:
Column Label Purpose
1 UID User ID. This is the integer value of the
user ID from the /etc/passwd file.
2 LOGNAME User login name. This is the alpha user
login name from the /etc/passwd file.
3 PRI_CPU Prime-time CPU run time. This is the
total time in seconds that prime-time CPU
run time was charged to the user during
the active accounting period.
4 NPRI_CPU Nonprime-time CPU run time. This is the
total time in seconds that nonprime-time
CPU run time was charged to the named
5 NPRI_MEM Prime-time memory K-core. This is a measure
of memory usage during prime time.
This value expresses the amount of memory
used and the elapsed amount of prime time
during which it was used (K-core is the
product of total CPU time in minutes and
mean size of memory used).
6 NPRI_MEM Nonprime-time memory K-core. This is a
measure of memory usage during nonprime
7 PRI_RD/WR Prime-time read and write characters.
This is the total number of characters
transferred during prime-time operation.
8 NPRI_RD/WR Nonprime-time read and write characters.
This is the total number of characters
transferred during nonprime-time operation.
9 PRI_BLKIO Prime-time number of I/O blocks. This is
the total number of I/O blocks transferred
during prime-time read and write
operations. The number of bytes in an
I/O block is implementation dependent.
10 NPRI_BLKIO Nonprime-time number of I/O blocks. This
is the total number of I/O blocks transferred
during nonprime-time read and
11 PRI_CONNECT Prime-time connect duration. This is the
total number of prime-time seconds during
which a connection existed
12 NPRI_CONNECT Nonprime-time connect duration. This is
the total number of nonprime-time seconds
during which a connection existed.
13 DSK_BLOCKS Disk blocks used. This is the total number
of disk blocks used.
14 PRINT Number of pages printed. This is the
total number of pages queued to any
printers in the system.
15 FEES Special fee charge units. This is the
number of integer units to charge for any
special fee. This value is the one supplied
when the /usr/sbin/acct/chargefee
command is processed during the active
16 PROCESSES Number of processes. This is the total
number of processes spawned by the user
during the active accounting period
17 SESS Number of logins. This is the total number
of times the user logged in during
the active accounting period.
18 DSAMPS Number of disk-accounting samples. This
is the total number of times during the
active accounting period that the diskaccounting
command was used to get the
total number of disk blocks listed in the
DSK_BLOCKS column. When the value in the
DSK_BLOCKS column is divide by this number,
the average number of disk blocks
used during the accounting period is
Total accounting records are read from standard input and
any additional files (up to nine) you specify with the
file operand. File records are merged according to identical
keys, usually the user ID and user login name. To
optimize processing performance, output is written in
binary, unless the -a or -v option is used.
Normally the acctmerg command is called from the runacct
shell procedure, either to produce an intermediate file
(/var/adm/acct/nite/daytacct, for example) when one or
more source accounting files is full, or to merge intermediate
files into a cumulative total
(/var/adm/acct/sum/tacct, is another example). The cumulative
total daily files are the source from which the
monacct command produces an ASCII monthly summary file,
which is written to the /var/adm/acct/fiscal subdirectory.
The optional specification operand allows you to select
input or output column entries, as illustrated in Example
1. Field specifications are a comma-separated string of
field numbers. Field numbers are referenced in boldface
type in the first column of the foregoing list together
with their respective column headings. When you specify
field numbers they should be listed in the order specified
by the boldfaced heading reference numbers.
Inclusive field ranges may also be specified, with array
sizes properly taken into account except for the ta_name
number of characters. For example, -h2-3,11,15-13,2 displays
the LOGNAME (2), PRI_CPU (3), PRI_CONNECT time (11),
FEES (15), PRINT (14), DISK_BLOCKS (13), and again LOGNAME
(2), in that order, with the described column headings
(-h). The default specification is to output all 18
columns (1-18 or 1-), which produces rather wide output
records that contain all the available accounting data.
Queuing system, disk usage, or fee data can be converted
intotacct records with the acctmerge command, using the -i
option and the specification operand.
To merge inclusive fields from an ASCII disk-accounting
file called dacct into an existing total-accounting file
named tacct as binary information, but with entries for
fields 1, 2, 13, and 18 only, enter the following line:
acctmerg -i1,-2,13,18 <dacct | acctmerg tacct >output
The acctmerg command reads the columnar entries for
UID (1), LOGNAME (2), DSK_BLOCKS (13), and DSAMPS
(18) from the dacct file as input, merges this
information as tacct binary records, and writes the
result to standard output as ASCII. To repair file
jan2.rpt in inclusive tacct columnar format, enter
the following initial command, edit the jan2.tmp
file, and then enter the last command: acctmerg -v
Edit jan2.tmp as desired.... acctmerg -i
The first command redirects the content of file
jan2.rpt to file jan2.tmp, with ASCII output and
floating-point values. After you edit file
jan2.tmp, the last command redirects file jan2.tmp
as ASCII input to file jan2.rpt as output, with
output records in binary.
Specifies the command path. Accounting header files that
define formats for writing accounting files. This is
where prime time is set. Intermediate daily totalaccounting
file. Cumulative total-accounting file.
