UTX(8)							    BSD System Manager's Manual 						    UTX(8)

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.
