NAME
       sa, accton - system accounting

SYNOPSIS
       sa [ -abcdDfijkKlnrstu ] [ -v threshold ] [ -S savacctfile ] [ -U usracctfile ] [ file ]

       accton [ file ]

DESCRIPTION
       With  an argument naming an existing file, accton causes system accounting 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 condensation 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 averaged core usage (in 1k units), "avio"
       for average number of i/o operations 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 sometimes appear.

       There are near a googol of options:

       a      Print all command names, even those containing  unprintable  characters  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 cat-
	      egory `**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

SEE ALSO
       ac(8), acct(2)

BUGS
       The number of options to this program is absurd.
