acctcon(1M)                                                     acctcon(1M)


   NAME
         acctcon, acctcon1, acctcon2 - connect-time accounting

   SYNOPSIS
         /usr/lib/acct/acctcon [options]

         /usr/lib/acct/acctcon1 [options]

         /usr/lib/acct/acctcon2

   DESCRIPTION
         acctcon converts a sequence of login/logoff records to total
         accounting records (see the tacct format in acct(4)).  login/logoff
         records are read from standard input.  The file /var/adm/wtmp is
         usually the source of the login/logoff records, however, because it
         may contain corrupted records or system date changes, it should first
         be fixed using wtmpfix.  The fixed version of file /var/adm/wtmp can
         then be redirected to acctcon.  The tacct records are written to
         standard output.  Here are the options for acctcon:

         -l file   file is created to contain a summary of line usage showing
                   line name, number of minutes used, percentage of total
                   elapsed time used, number of sessions charged, number of
                   logins, and number of logoffs.  This file helps track line
                   usage, identify bad lines, and find software and hardware
                   oddities.  Hangup, termination of login(1) and termination
                   of the login shell each generate logoff records, so that
                   the number of logoffs is often three to four times the
                   number of sessions.  See init(1M) and utmp(4).
         -o file   file is filled with an overall record for the accounting
                   period, giving starting time, ending time, number of
                   reboots, and number of date changes.

         acctcon is a combination of the programs acctcon1 and acctcon2.
         acctcon1 converts login/logoff records, taken from the fixed
         /var/adm/wtmp file, to ASCII output.  acctcon2 reads the ASCII
         records produced by acctcon1 and converts them to tacct records.
         acctcon1 can be used with the -l and -o options, described above, as
         well as with the following options:

         -p    Print input only, showing line name, login name, and time (in
               both numeric and date/time formats).

         -t    acctcon1 maintains a list of lines on which users are logged
               in.  When it reaches the end of its input, it emits a session
               record for each line that still appears to be active.  It
               normally assumes that its input is a current file, so that it
               uses the current time as the ending time for each session still
               in progress.  The -t flag causes it to use, instead, the last
               time found in its input, thus assuring reasonable and
               repeatable numbers for non-current files.

   acctcon(1M)                                                     acctcon(1M)


   EXAMPLES
         The acctcon command is typically used as follows:
           acctcon -l lineuse -o reboots < tmpwtmp > ctacct

         The acctcon1 and acctcon2 commands are typically used as follows:
           acctcon1 -l lineuse -o reboots < tmpwtmp | sort +1n +2 > ctmp
           acctcon2 < ctmp > ctacct

   FILES
         /var/adm/wtmp

   NOTES
         The line usage report is confused by date changes.  Use wtmpfix (see
         fwtmp(1M)), with the /var/adm/wtmp file as an argument, to correct
         this situation.
