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
Lists input but without processing.
-t Produces a single record that contains the totals of all input.
-u 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 floating-point
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
User ID. This is the integer value of the
user ID from the /etc/passwd file.
User login name. This is the alpha user
login name from the /etc/passwd file.
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.
Nonprime-time CPU run time. This is the
total time in seconds that nonprime-time
CPU run time was charged to the named
Prime-time memory K-core. This is a meas-
ure 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).
Nonprime-time memory K-core. This is a
measure of memory usage during nonprime
Prime-time read and write characters.
This is the total number of characters
transferred during prime-time operation.
Nonprime-time read and write characters.
This is the total number of characters
transferred during nonprime-time opera-
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.
Nonprime-time number of I/O blocks. This
is the total number of I/O blocks
transferred during nonprime-time read and
Prime-time connect duration. This is the
total number of prime-time seconds during
which a connection existed
Nonprime-time connect duration. This is
the total number of nonprime-time seconds
during which a connection existed.
Disk blocks used. This is the total
number of disk blocks used.
Number of pages printed. This is the
total number of pages queued to any
printers in the system.
Special fee charge units. This is the
number of integer units to charge for any
special fee. This value is the one sup-
plied when the /usr/sbin/acct/chargefee
command is processed during the active
Number of processes. This is the total
number of processes spawned by the user
during the active accounting period
Number of logins. This is the total
number of times the user logged in during
the active accounting period.
Number of disk-accounting samples. This
is the total number of times during the
active accounting period that the disk-
accounting 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 exam-
ple, -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 specif-
ication 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
1. 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 -i 1 -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.
2. To repair file jan2.rpt in inclusive tacct columnar format, enter the
following initial command, edit the jan2.tmp file, and then enter the
acctmerg -v <<jan2.rpt >>jan2.tmp
Edit jan2.tmp as desired....
acctmerg -i >>jan2.tmp >>jan2.rpt
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.
