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 account-
     ing records. 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 binary
     records are written to standard output.

OPTIONS
     -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 binary 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

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.

FILES
