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.

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.
