Name
       sa, accton - print process accounting statistics

Syntax
       /etc/sa [ options ] [ file ]

       /etc/accton [ file ]

Arguments
       file    With  an	 argument  naming  an  existing	 file,	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.

Description
       The command reports on, cleans up, and generally	 maintains  accounting
       files.

       The  is	able  to condense the information in into a summary file 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 can grow by 100 blocks per day.  The summary file is  nor‐
       mally  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.	The file is the default.

       Output  fields  are  labeled: “cpu” for the sum of user+system time (in
       cpu seconds), “re” for real time (also in cpu seconds),	“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 sec‐
       onds), “u” and “s” for user and system cpu time alone (both in cpu sec‐
       onds) will sometimes appear.

Options
       -a      List  all  command names including those containing unprintable
	       characters and those used only once.  By	 default,  places  all
	       command	names containing unprintable characters and those used
	       only once 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 option.

       -i      Do not read in summary file.

       -j      Instead of total minutes 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 when done.

       -t      For each command, report ratio of real time to the sum of  user
	       and  system  times.  If the sum of user and system times is too
	       small to report, `*ignore*' appears in this field.

       -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.

Restrictions
       Accounting is suspended when there is less than 2% free space on	 disk.
       Accounting resumes when free space rises above 4%.

Files
       Raw accounting
