     sa - Shell accounting

     sa [ -abcjlnrstuv ] [ file ]

     When a user logs in, if the Shell is able to open the file
     /usr/adm/sha, then as each command completes the Shell
     writes at the end of this file the name of the command, the
     user, system, and real time consumed, and the user ID.  Sa
     reports on, cleans up, and generally maintains this and
     other accounting files.  To turn accounting on and off, the
     accounting file must be created or destroyed externally.

     Sa is able to condense the information in /usr/adm/sha into
     a summary file /usr/adm/sht 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 sha can grow by 100 blocks per day.  The
     summary file is 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; sha is the default.
     There are zillions of options:

     a  Place 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 sys-
        tem times.

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

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

     l  Separate system and user time; normally they are com-

     n  Sort by number of calls.

     r  Reverse order of sort.

     s  Merge accounting file into summary file /usr/adm/sht when

     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 day of the year, time, day of the
        week, user ID and command name.

     v  If the next character is a digit n, then type the name of
        each command used n times or fewer.  Await a reply from
        the typewriter; if it begins with ``y'', add the command
        to the category ``**junk**.''  This is used to strip out

     /usr/adm/sha    accounting
     /usr/adm/sht    summary
