acctprc, acctprc1, acctprc2 - process accounting



/usr/lib/acct/acctprc1 [ctmp]



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.


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

acctcom(1), acct(2), acct.h(3HEAD), utmpx(5), attributes(7), acct(8),
acctcms(8), acctcon(8), acctmerg(8), acctsh(8), cron(8), fwtmp(8),


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.
