acctcms - command summary from per-process accounting records
/usr/lib/acct/acctcms [-a [-p] [-o]] [-c] [-j] [-n] [-s] [-t] files
acctcms reads one or more files, normally in the form described in
acct(4). It adds all records for processes that executed identically
named commands, sorts them, and writes them to the standard output,
normally using an internal summary format. The options are:
-a Print output in ASCII rather than in the internal summary format.
The output includes command name, number of times executed, total
kcore minutes, total CPU minutes, total real minutes, mean size (in
kilobytes), mean CPU minutes per invocation, hog factor, characters
transferred, and blocks read and written, as in acctcom(1). Output
is normally sorted by total kcore minutes.
-c Sort by total CPU time, rather than by total kcore minutes.
-j Combine all commands invoked only once under ``***other.''
-n Sort by number of command invocations.
-s Any filenames encountered hereafter are already in internal summary
-t Process all records as total accounting records. The default
internal summary format splits each field into prime- and nonprimetime
parts. This option combines the prime- and nonprime-time parts
into a single field that is the total of both and provides upward
compatibility with old-style (that is, pre-UNIX System V Release
4.0) acctcms internal summary format records.
The following options can be used only with the -a option.
-p Output a prime-time-only command summary.
-o Output a nonprime-time only (offshift) command summary.
When -p and -o are used together, a combination prime- and nonprime-time
report is produced. All the output summaries are total usage except
number of times executed, CPU minutes, and real minutes, which are split
into prime and nonprime.
acctcms checks the environment variable ACCT_CSIZE to figure out the
maximum number of distinct commands it might need to report.
A typical sequence for performing daily command accounting and for
maintaining a running total is:
acctcms file ... > today
cp total previoustotal
acctcms -s today previoustotal > total
acctcms -a -s today
acct(1M), acctcom(1), acctcon(1M), acctmerg(1M), acctprc(1M), acctsh(1M),
fwtmp(1M), runacct(1M), acct(2), acct(4), utmp(4).
Unpredictable output results if -t is used on new-style internal summary
format files or if it is not used with old-style internal summary format
