ACCTPRC(8) Maintenance Commands and Procedures ACCTPRC(8)
NAME
acctprc, acctprc1, acctprc2 - process accounting
SYNOPSIS
/usr/lib/acct/acctprc /usr/lib/acct/acctprc1 [
ctmp]
/usr/lib/acct/acctprc2DESCRIPTION
acctprc reads the standard input and converts it to total accounting
records (see the
tacct record in
acct.h(3HEAD)).
acctprc divides CPU
time into prime time and non-prime time and determines mean memory
size (in memory segment units).
acctprc then summarizes the
tacct records, according to user IDs, and adds login names corresponding to
the user IDs. The summarized records are then written to the standard
output.
acctprc1 reads input in the form described by
acct.h(3HEAD),
adds login names corresponding to user
IDs, then writes for each
process an
ASCII line giving user
ID, login name, prime
CPU time
(tics), non-prime
CPU time (tics), and mean memory size (in memory
segment units). If
ctmp is given, it should contain a list of login
sessions sorted by user
ID and login name. If this file is not
supplied, it obtains login names from the password file, just as
acctprc does. The information in
ctmp helps it distinguish between
different login names that share the same user
ID. From the standard input,
acctprc2 reads records in the form written
by
acctprc1, summarizes them according to user
ID and name, then
writes the sorted summaries to the standard output as total
accounting records.
EXAMPLES
Example 1: Examples of acctprc.
The
acctprc command is typically used as shown below:
example% acctprc < /var/adm/pacct > ptacct
The
acctprc1 and
acctprc2s commands are typically used as shown
below:
example% acctprc1 ctmp </var/adm/pacct
example% acctprc2 > ptacct
FILES
/etc/passwd system password file

Although it is possible for
acctprc1 to distinguish among login names
that share user
IDs for commands run from a command line, it is
difficult for
acctprc1 to make this distinction for commands invoked
in other ways. A command run from
cron(8) is an example of where
acctprc1 might have difficulty. A more precise conversion can be done
using the
acctwtmp program in
acct(8).
acctprc does not distinguish
between users with identical user IDs.
A memory segment of the mean memory size is a unit of measure for the
number of bytes in a logical memory segment on a particular
processor.
During a single invocation of any given command, the
acctprc,
acctprc1, and
acctprc2 commands can process a maximum of
o 6000 distinct sessions
o 1000 distinct terminal lines
o 2000 distinct login names
If at some point the actual number of any one of these items exceeds
the maximum, the command will not succeed.
