acctcon1, acctcon2 - Display connect-time accounting summaries
acctcon1 [-l file] [-o file] [-p] [-t]
Writes line-usage format from the input file (usually
/var/adm/wtmp) to file for the accounting period during
which the file /var/adm/wtmp is active.
The following example shows the ASCII line-usage heading format:
TOTAL DURATION: 57 MINUTES
LINE MINUTES PERCENT # SESS # ON # OFF
pty/ttyp4 37 64 3 3 7
console 26 45 2 2 4
pty/ttyp5 7 11 1 1 3
pty/ttyp6 0 0 0 0 2
TOTALS 69 - 6 6 16
TOTAL DURATION specifies the total number of minutes used for connect
sessions during the accounting period during which the
/var/adm/wtmp file is active.
The columns specify the line name, the number of session minutes used,
the percentage of total elapsed time used for the sessions, the number
of sessions charged, the number of logins, and the number of logouts.
The last line in the line-usage file totals the entries for each column.
The line-usage format helps to track line usage and identify bad
All hangups, terminations of the login command, and terminations
of the login shell cause the system to write logout records, so that
the number of logouts is often greater than the number of sessions.
Writes an overall-record format to file from the input file
(usually /var/adm/wtmp) for the accounting period during which
the /var/adm/wtmp file is active.
The following example shows the overall-record format:
from mon day date hh:mm:ss yyyy tz
to mon day date hh:mm:ss yyyy tz
2 date changes Number of times the date was changed.
21 acctg off Number of times accounting functions
were turned off.
25 run-level S Number of times accounting functions
ran in single-user mode.
108 system boot Number of times the system was rebooted.
21 acctg on Number of times accounting functions
were turned on.
21 acctcon1 Number of times the acctcon1 command
The first lines specify the date and time stamp, including time zone,
of the accounting period start time and end time.
Writes the input file (usually /var/adm/wtmp) to the default

The output columnar format lists the line reference name, the login
name, the time in seconds since January 1, 1970, 0 hours, 0 minutes, 0
seconds, the date, the 24-hour clock time, the year, and the time zone.
Uses the last time found in the input file as the ending time for any
This time, rather than current time, is necessary to have reasonable
and repeatable values for noncurrent files.
The output format is the same as the default output format.
The acctcon1 command also maintains a list of ports on which
users are logged in.
When the acctcon1 command reaches the end of its input, a
session record is written for each port that still appears to be
The acctcon1 command assumes that the input source is the
current file and uses current time as the ending time for each session
still in progress.
The acctcon1 and acctcon2 commands are described
The acctcon1 command is invoked by the runacct shell
procedure to write a sequence of login and logout records.
One record for each connect session is written to the specified
destination as a sequence of login session records.
The /var/adm/wtmp source file should be directed as input to the

The columns contain the following information:
Device address, expressed as a decimal equivalent of the
major/minor device address at which the connection was activated.
User ID assigned for the connect-session record.
Login name under which the session took place.
Total number of prime-time seconds for the connect session.
Total number of nonprime-time seconds for the connect session.
Seconds since the date 0 hours, 0 minutes 0 seconds, 1 January 1970.
Month, day of the month, connect-session starting time, year, and time zone.
The order of date and time information is locale dependent.
The timestamps shown use the default format for date and time values;
however, you can define the NLTIME environment variable to change
The acctcon2 command is invoked by the runacct shell
It converts a sequence of login session records produced by the
acctcon1 command into connect-time total accounting records.
These records are often merged with other total accounting records
with the acctmerg command to produce a daily report.
The following example converts login records to a default format login
session record report:
acctcon1 -t /var/adm/lineuse -o /var/adm/reboots \
< /var/adm/wtmp > /var/adm/logsess
The previous example generates three files.
The /var/adm/logsess file lists ending date and 24-hour
timestamp records that correspond with the last time that input was
obtained with the -t flag.
For the accounting period covered by the /var/adm/wtmp file, the
/var/adm/lineuse line-usage summary file is generated by the
-l flag, and the /var/adm/reboots overall record file is
obtained with the -o flag.
The following example converts a series of login session records in the
/var/adm/logsess file to a total accounting record in the
/var/adm/logacct binary file:
acctcon2 < /var/adm/logsess > /var/adm/logacct
