acctcon converts a sequence of login/logoff records to total accounting
records (see the tacct format in acct(4)
). The 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.
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 below, as well
as with the -p and -t 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.
- -l lineuse
- lineuse 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 reboot
- reboot is filled with an overall record for the accounting period,
giving starting time, ending time, number of reboots, and number of date
changes.
The acctcon command is typically used as follows: example%
acctcon -l lineuse -o reboots < tmpwtmp > ctacct
The acctcon1 and acctcon2
commands are typically used as follows:
example% acctcon1 -l lineuse -o reboots
< tmpwtmp | sort +1n +2 > ctmp
example% acctcon2 < ctmp > ctacct

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.
The acctcon, acctcon1, and acctcon2 commands can process a maximum
of
6000 distinct sessions
1000 distinct terminal lines
2000 distinct login names
during a single invocation of any given command. If at some point the actual
number of any one of these items exceeds the maximum, the command will
not succeed.
