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 for-
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 ses-
sion 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 lines.
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.
-p Writes the input file (usually /var/adm/wtmp) to the default output
device. For example:
pty/ttyp1 hoff 616883748 Jul 19 16:35:48 1990 EST
pty/ttyp1 hoff 616883825 Jul 19 16:37:05 1990 EST
pty/ttyp1 LOGIN 616883833 Jul 19 16:37:13 1990 EST
pty/ttyp1 tom 616883837 Jul 19 16:37:17 1990 EST
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.
-t Uses the last time found in the input file as the ending time for any
current processes. 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
active. 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 separately.
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 following example shows the default ASCII columnar output format:

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
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 this format.
The acctcon2 command is invoked by the runacct shell procedure. 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
1. 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
This 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 option. For the account-
ing period covered by the /var/adm/wtmp file, the /var/adm/lineuse
line-usage summary file is generated by the -l option, and the
/var/adm/reboots overall record file is obtained with the -o option.
2. 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
