NAME
       sa, accton - system accounting

SYNOPSIS
       /etc/sa  [ -abcdDfijkKlnrstuv ] [ -S savacctfile ] [ -U usracctfile ] [
       file ]

       /etc/accton [ file ]

DESCRIPTION
       With an argument naming an existing file, accton causes system account‐
       ing  information  for every process executed to be placed at the end of
       the file.  If no argument is given, accounting is turned off.

       Sa reports on, cleans up, and generally maintains accounting files.

       Sa is able to condense the information in /usr/adm/acct into a  summary
       file  /usr/adm/savacct  which  contains  a count of the number of times
       each command was called and the time resources consumed.  This  conden‐
       sation is desirable because on a large system /usr/adm/acct can grow by
       100 blocks per day.  The summary  file  is  normally  read  before  the
       accounting file, so the reports include all available information.

       If a file name is given as the last argument, that file will be treated
       as the accounting file; /usr/adm/acct is the default.

       Output fields are labeled: “cpu” for the sum of  user+system  time  (in
       minutes),  “re” for real time (also in minutes), “k” for cpu-time aver‐
       aged core usage (in 1k units), “avio” for average number of i/o  opera‐
       tions  per  execution.  With options fields labeled “tio” for total i/o
       operations, “k*sec” for cpu storage integral (kilo-core  seconds),  “u”
       and “s” for user and system cpu time alone (both in minutes) will some‐
       times appear.

       There are near a googol of options:


       a      Print all command names, even those containing unprintable char‐
              acters  and  those used only once.  By default, those are placed
              under the name ‘***other.’

       b      Sort output by sum of user and system time divided by number  of
              calls.  Default sort is by sum of user and system times.

       c      Besides total user, system, and real time for each command print
              percentage of total time over all commands.

       d      Sort by average number of disk i/o operations.

       D      Print and sort by total number of disk i/o operations.

       f      Force no interactive threshold compression with -v flag.

       i      Don’t read in summary file.

       j      Instead of total minutes time for each  category,  give  seconds
              per call.

       k      Sort by cpu-time average memory usage.

       K      Print and sort by cpu-storage integral.

       l      Separate system and user time; normally they are combined.

       m      Print  number  of  processes  and number of CPU minutes for each
              user.

       n      Sort by number of calls.

       r      Reverse order of sort.

       s      Merge accounting file into summary  file  /usr/adm/savacct  when
              done.

       t      For  each  command  report ratio of real time to the sum of user
              and system times.

       u      Superseding all other flags,  print  for  each  command  in  the
              accounting file the user ID and command name.

       v      Followed  by  a  number n, types the name of each command used n
              times or fewer.  Await a reply from the terminal; if  it  begins
              with  ‘y’,  add  the command to the category ‘**junk**.’ This is
              used to strip out garbage.

       S      The following filename is  used  as  the  command  summary  file
              instead of /usr/adm/savacct.

       U      The  following  filename  is used instead of /usr/adm/usracct to
              accumulate the per-user statistics printed by the -m option.

FILES
       /usr/adm/acct       raw accounting
       /usr/adm/savacct    summary
       /usr/adm/usracct    per-user summary

BUGS
       The number of options to this program is absurd.
