    DESCRIPTION

           sa summarizes information about previously executed commands as
           recorded in the acct file.  In addition, it condenses this data into a
           summary file named savacct which contains the number of times the
           command was called and the system resources used.  The information can
           also be summarized on a per-user basis; sa will save this information
           into a file named usracct.
    
           If no arguments are specified, sa will print information about all of
           the commands in the acct file.
    
           If called with a file name as the last argument, sa will use that file
           instead of the system's default acct file.
    
           By default, sa will sort the output by sum of user and system time.  If
           command names have unprintable characters, or are only called once, sa
           will sort them into a group called '***other'.  If more than one
           sorting option is specified, the list will be sorted by the one
           specified last on the command line.
    
           The output fields are labeled as follows:
    
           cpu     sum of system and user time in cpu minutes
    
           re      "elapsed time" in minutes
    
           k       cpu-time averaged core usage, in 1k units
    
           avio    average number of I/O operations per execution
    
           tio     total number of I/O operations
    
           k*sec   cpu storage integral (kilo-core seconds)
    
           flags like '--print-seconds' and '--sort-num-calls' when printing out
           commands when combined with the '--user-summary' or '--print-users'
           flags.  GNU sa pays attention to these flags if they are applicable.
           Also, MIPS' sa stores the average memory use as a short rather than a
           double, resulting in some round-off errors.  GNU sa uses double the
           whole way through.
    
    
    

    OPTIONS

           The availability of these program options depends on your operating
           system.  In specific, the members that appear in the struct acct of
           your system's process accounting header file (usually acct.h )
           determine which flags will be present.  For example, if your system's
           struct acct doesn't have the 'ac_mem' field, the installed version of
           sa will not support the '--sort-cpu-avmem', '--sort-ksec', '-k', or
           '-K' options.
    
           In short, all of these flags may not be available on your machine.
    
           -a, --list-all-names
                  Force sa not to sort those command names with unprintable
                  characters and those used only once into the ***other group.
           -b, --sort-sys-user-div-calls
                  Sort the output by the sum of user and system time divided by
                  the number of calls.
           -c, --percentages
                  Print percentages of total time for the command's user, system,
                  and real time values.
           -d, --sort-avio
                  Sort the output by the average number of disk I/O operations.
           -D, --sort-tio
                  Print and sort the output by the total number of disk I/O
                  operations.
           -f, --not-interactive
                  When using the '--threshold' option, assume that all answers to
                  interactive queries will be affirmative.
           -i, --dont-read-summary-file
                  Don't read the information in the system's default savacct file.
           -j, --print-seconds
                  Instead of printing total minutes for each category, print
                  seconds per call.
           -k, --sort-cpu-avmem
                  Sort the output by cpu time average memory usage.
           -K, --sort-ksec
                  Print and sort the output by the cpu-storage integral.
           -l, --separate-times
                  Print separate columns for system and user time; usually the two
                  are added together and listed as 'cpu'.
           -m, --user-summary
                  Print the number of processes and number of CPU minutes on a
                  per-user basis.
           -n, --sort-num-calls
                  Sort the output by the number of calls.  This is the default
                  too small to report--the sum is zero--'*ignore*' will appear in
                  this field.
           -u, --print-users
                  For each command in the accounting file, print the userid and
                  command name.  After printing all entries, quit.  *Note*: this
                  flag supersedes all others.
           -v num --threshold num
                  Print commands which were executed num times or fewer and await
                  a reply from the terminal.  If the response begins with 'y', add
                  the command to the '**junk**' group.
           --separate-forks
                  It really doesn't make any sense to me that the stock version of
                  sa separates statistics for a particular executable depending on
                  whether or not that command forked.  Therefore, GNU sa lumps
                  this information together unless this option is specified.
           --ahz hz
                  Use this flag to tell the program what AHZ should be (in hertz).
                  This option is useful if you are trying to view an acct file
                  created on another machine which has the same byte order and
                  file format as your current machine, but has a different value
                  for AHZ.
           --debug
                  Print verbose internal information.
           -V, --version
                  Print the version number of sa.
           -h, --help
                  Prints the usage string and default locations of system files to
                  standard output and exits.
           --sort-real-time
                  Sort the output by the "real time" field.
           --other-usracct-file filename
                  Write summaries by user ID to filename rather than the system's
                  default usracct file.
           --other-savacct-file filename
                  Write summaries by command name to filename rather than the
                  system's default SAVACCT file.
           --other-file filename
                  Read from the file filename instead of the system's default ACCT
                  file.
    
    

    FILES

           acct   The raw system wide process accounting file. See acct(5) (or
                  pacct(5)) for further details.
           savacct
                  A summary of system process accounting sorted by command.
           usracct

    BUGS

           There is not yet a wide experience base for comparing the output of GNU
           sa with versions of sa in many other systems.  The problem is that the
           data files grow big in a short time and therefore require a lot of disk
           space.
