NAME

     utx -- manage the user accounting database

SYNOPSIS

     utx boot
     utx shutdown
     utx rm identifier ...

DESCRIPTION

     The utx utility can be used to perform operations on the user accounting database, as done by pututxline(3).

     The first argument to utx indicates an action to be performed:

     boot      Write a boot time record to the user accounting database.  This option should typically only be used by rc(8).

     shutdown  Write a shutdown time record to the user accounting database.  This option should typically only be used by rc(8).

     rm        Remove stale sessions from the user accounting database, by referring to their identifier.  Stale sessions can occur if a login
	       service exits prematurely or fails to remove the session from the accounting database.

	       Utilities such as w(1) will not display the identifier corresponding with a login session, since its value is typically only of use
	       by the process managing the record.  The following command can be used to obtain all records from the user accounting database's
	       active session table, including its identifiers:

		     getent utmpx active

	       Identifiers can either be supplied in hexadecimal form as displayed by getent(1), or as a string if the identifier allows such a
	       representation.

     Because this utility requires write-access to the user accounting database, its use is limited to the super-user.

HISTORY

     The utx utility replaced utxrm in FreeBSD 10.0.

NAME

     ac -- connect time accounting

SYNOPSIS

     ac [-dp] [-t tty] [-w wtmp] [users ...]

DESCRIPTION

     If the file /var/log/utx.log exists, a record of individual login and logout times are written to it by login(1) and init(8), respectively.
     The ac utility examines these records and writes the accumulated connect time (in hours) for all logins to the standard output.

     The options are as follows:

     -d 	Display the connect times in 24 hour chunks.

     -p 	Print individual users' totals.

     -t tty	Only do accounting logins on certain ttys.  The tty specification can start with '!' to indicate not this tty and end with '*' to
		indicate all similarly named ttys.  Multiple -t flags may be specified.

     -w wtmp	Read connect time data from wtmp instead of the default file, /var/log/utx.log.

     users ...	Display totals for the given individuals only.

     If no arguments are given, ac displays the total connect time for all accounts with login sessions recorded in utx.log.

     The default utx.log file will increase without bound unless it is truncated.  It is normally truncated by the daily scripts run by cron(8),
     which rename and rotate the utx.log files, keeping a week's worth of data on hand.  No login or connect time accounting is performed if
     /var/log/utx.log does not exist.

FILES

     /var/log/utx.log  connect time accounting file

EXIT STATUS

     The ac utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     Allow times recorded in modems to be charged out at a different rate than other:

	   ac -p -t "ttyd*" > modems
	   ac -p -t "!ttyd*" > other
