acctcon, acctcon1, acctcon2 - connect-time accounting
/usr/lib/acct/acctcon [-l lineuse] [-o reboot]
/usr/lib/acct/acctcon1 [-p] [-t] [-l lineuse] [-o reboot]
acctcon converts a sequence of login/logoff records to total
accounting records (see the tacct format in acct(3HEAD)).
The login/logoff records are read from standard input. The
file /var/adm/wtmpx is usually the source of the
login/logoff records; however, because it might contain cor-
rupted records or system date changes, it should first be
fixed using wtmpfix. The fixed version of file
/var/adm/wtmpx can then be redirected to acctcon. The tacct
records are written to standard output.
acctcon is a combination of the programs acctcon1 and acct-
con2. acctcon1 converts login/logoff records, taken from the
fixed /var/adm/wtmpx 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
-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 pro-
gress. 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.
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, ter-
mination 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 utmpx(4).
reboot is filled with an overall record for the
accounting period, giving starting time, ending time,
number of reboots, and number of date changes.
Example 1: Using the acctcon command.
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
example% acctcon1 -l lineuse -o reboots < tmpwtmp | sort +1n +2 > ctmp
example% acctcon2 < ctmp > ctacct

System Administration Guide: Basic Administration
The line usage report is confused by date changes. Use
wtmpfix (see fwtmp(1M)), with the /var/adm/wtmpx file as an
argument, to correct this situation.
During a single invocation of any given command, the acct-
con, acctcon1, and acctcon2 commands can process a maximum
o 6000 distinct session
o 1000 distinct terminal lines
o 2000 distinct login names
If at some point the actual number of any one of these
items exceeds the maximum, the command will not succeed.
