NAME

acctcom - search and print process accounting files

SYNOPSIS

acctcom [-abfhikmqrtv] [-C sec] [-e time] [-E time] 
    [-g group] [-H factor] [-I chars] [-l line] 
    [-n pattern] [-o output-file] [-O sec] [-s time] 
    [-S time] [-u user] [filename]...

DESCRIPTION

The acctcom utility reads filenames, the standard input, or /var/adm/pacct, in the form described by acct.h(3HEAD) and writes selected records to standard output. Each record represents the execution of one process. The output shows the COMMAND NAME, USER, TTYNAME, START TIME, END TIME, REAL (SEC), CPU (SEC), MEAN SIZE (K), and optionally, F (the fork()/exec() flag: 1 for fork() without exec()), STAT (the system exit status), HOG FACTOR, KCORE MIN, CPU FACTOR, CHARS TRNSFD, and BLOCKS READ (total blocks read and written).

A `#' is prepended to the command name if the command was executed with super-user privileges. If a process is not associated with a known terminal, a `?' is printed in the TTYNAME field.

If no filename is specified, and if the standard input is associated with a terminal or /dev/null (as is the case when using `&' in the shell), /var/adm/pacct is read; otherwise, the standard input is read.

If any filename arguments are given, they are read in their respective order. Each file is normally read forward, that is, in chronological order by process completion time. The file /var/adm/pacct is usually the current file to be examined; a busy system may need several such files of which all but the current file are found in /var/adm/pacctincr.

OPTIONS

The following options are supported:

-a

: Show some average statistics about the processes selected. The statistics will be printed after the output records.

-b

: Read backwards, showing latest commands first. This option has no effect when standard input is read.

-f

: Print the fork()/exec() flag and system exit status columns in the output. The numeric output for this option will be in octal.

-h

: Instead of mean memory size, show the fraction of total available CPU time consumed by the process during its execution. This "hog factor" is computed as (total CPU time)/(elapsed time).

-i

: Print columns containing the I/O counts in the output.

-k

: Instead of memory size, show total kcore-minutes.

-m

: Show mean core size (the default).

-q

: Do not print any output records, just print the average statistics as with the -a option.

-r

: Show CPU factor (user-time/(system-time + user-time)).

-t

: Show separate system and user CPU times.

-v

: Exclude column headings from the output.

-C sec

: Show only processes with total CPU time (system-time + user-time) exceeding sec seconds.

-e time

: Select processes existing at or before time.

-E time

: Select processes ending at or before time. Using the same time for both -S and -E shows the processes that existed at time.

-g group

: Show only processes belonging to group. The group may be designated by either the group ID or group name.

-H factor

: Show only processes that exceed factor, where factor is the "hog factor" as explained in option -h above.

-I chars

: Show only processes transferring more characters than the cutoff number given by chars.

-l line

: Show only processes belonging to terminal /dev/term/line.

-n pattern

: Show only commands matching pattern that may be a regular expression as in regcmp(3C), except + means one or more occurrences.

-o output-file

: Copy selected process records in the input data format to output-file; suppress printing to standard output.

-O sec

: Show only processes with CPU system time exceeding sec seconds.

-s time

: Select processes existing at or after time, given in the format hr[:min[:sec]].

-S time

: Select processes starting at or after time.

-u user

: Show only processes belonging to user. The user may be specified by a user ID, a login name that is then converted to a user ID, `#' (which designates only those processes executed with superuser privileges), or `?' (which designates only those processes associated with unknown user IDs).
