acctprc, acctprc1, acctprc2 - process accounting
acctprc reads standard input, in the form described by acct(4), and
converts it to total accounting records (see the tacct record in
acct(4)). acctprc divides CPU time into prime time and nonprime 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 standard output. acctprc1 reads input in the form described by
acct(4), adds login names corresponding to user IDs, then writes for each
process an ASCII line giving user ID, login name, prime CPU time (tics),
nonprime CPU time (tics), and mean memory size (in memory segment units).
If ctmp is given, it is expected to 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
sharing the same user ID.
From 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.
acctprc1 checks the environment variable ACCT_A_SSIZE to figure out the
maximum number of sessions that it might need to report in one accounting
All three of these commands check the environment variable ACCT_A_USIZE
to figure out the maximum number of distinct login names that need to be
reported in one accounting run.
The acctprc command is typically used as shown below:
acctprc < /var/adm/pacct > ptacct
The acctprc1 and acctprc2 commands are typically used as shown below:
acctprc1 ctmp < /var/adm/pacct | acctprc2 > ptacct
acct(1M), acctcms(1M), acctcom(1), acctcon(1M), acctmerg(1M), acctsh(1M),
cron(1M), fwtmp(1M), runacct(1M), acct(2), acct(4), utmp(4).
Although it is possible for acctprc1 to distinguish among login names
that share user IDs for commands run normally, it is difficult to do this
for those commands run from cron(1M), for example. A more precise
conversion can be done using the acctwtmp program in acct(1M). 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.
