Looking at the `pacct` File With `acctcom`

At any time, you can examine the contents of the /var/adm/pacctn files, or any file with records in the acct.h format, by using the acctcom program. If you don't specify any files and don't provide any standard input when you run this command, acctcom reads the pacct file. Each record read by acctcom represents information about a dead process (active processes may be examined by running the ps command). The default output of acctcom provides the following information:

Command name (pound (#) sign if it was executed with superuser privileges)
User
tty name (listed as ? if unknown)
Starting time
Ending time
Real time (in seconds)
CPU time (in seconds)
Mean size (in Kbytes)

The following information can be obtained by using options to acctcom:

State of the fork/exec flag (1 for fork without exec)
System exit status
Hog factor
Total kcore minutes
CPU factor
Characters transferred
Blocks read

The following table describes the acctcom options.

Table 32-6 acctcom Options


Option	Description
`-a`	Shows some average statistics about the processes selected. (The statistics are printed after the output is recorded.)
`-b`	Reads the files backward, showing latest commands first. (This has no effect if reading standard input.)
`-f`	Prints the `fork/exec` flag and system exit status columns. (The output is an octal number.)
`-h`	Instead of mean memory size, shows the hog factor, which is the fraction of total available CPU time consumed by the process during its execution. Hog factor = total_CPU_time/elapsed_time.
`-i`	Prints columns containing the I/O counts in the output.
`-k`	Shows total `kcore` `minutes` instead of memory size.
`-m`	Shows mean core size (this is the default).
`-q`	Prints average statistics, not output records
`-r`	Shows CPU factor: `user_time`/(`system_time + user_tim`e).
`-t`	Shows separate system and user CPU times.
`-v`	Excludes column headings from the output.
`-C` `sec`	Shows only processes with total CPU time (system plus user) exceeding `sec` seconds.
`-e` `time`	Shows processes existing at or before `time`, given in the format hr[:min[:sec]].
`-E` `time`	Shows processes starting at or before `time`, given in the format hr[:min[:sec]]. Using the same time for both `-S` and `-E`, show processes that existed at the time.
`-g` `group`	Shows only processes belonging to `group`.
`-H` `factor`	Shows only processes that exceed `factor`, where `factor` is the "hog factor" (see the `-h` option).
`-I` `chars`	Shows only processes transferring more characters than the cutoff number specified by `chars`.
`-l` `line`	Show only processes belonging to the terminal `/dev/line`.
`-n` `pattern`	Shows only commands matching `pattern` (a regular expression except that "`+`" means one or more occurrences).
`-o` `ofile`	Instead of printing the records, copys them in `acct.h` format to `ofile`.
`-O` `sec`	Shows only processes with CPU system time exceeding `sec` seconds.
`-s` `time`	Show processes existing at or after `time`, given in the format `hr`[:`min`[:`sec`]].
`-S` `time`	Show processes starting at or after `time`, given in the format `hr`[:`min`[:`sec`]].
`-u` `user`	Shows only processes belonging to `user`.
