+.Sh NAME
+.Nm utx ,
+.Nm utxrm
+.Nd manage the user accounting database
+.Sh SYNOPSIS
+.Nm
+.Cm boot
+.Nm
+.Cm shutdown
+.Nm
+.Cm rm
+.Ar identifier
+.Ar ...
+.Nm utxrm
+.Ar identifier
+.Ar ...
+.Sh DESCRIPTION
+The
+.Nm
+utility can be used to perform operations on the user accounting
+database, as done by
+.Xr pututxline 3 .
+.Pp
+The first argument to
+.Nm
+indicates an action to be performed:
+.Bl -tag -width ".Cm shutdown"
+.It Cm boot
+Write a boot time record to the user accounting database.
+This option should typically only be used by
+.Xr rc 8 .
+.It Cm shutdown
+Write a shutdown time record to the user accounting database.
+This option should typically only be used by
+.Xr rc 8 .
+.It Cm rm
+Remove stale sessions from the user accounting
+database, by referring to their
+.Ar identifier .
+Stale sessions can occur if a login service exits prematurely or fails
+to remove the session from the accounting database.
+.Pp
+Utilities such as
+.Xr 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:
+.Pp
+.Dl getent utmpx active
+.Pp
+Identifiers can either be supplied in hexadecimal form as displayed by
+.Xr getent 1 ,
+or as a string if the identifier allows such a representation.
+.Pp
+To remain backward compatible, this action can also be invoked directly
+by using the
+.Nm utxrm
+command.
+.El
+.Pp
+.Pp
+Because this utility requires write-access to the user accounting
+database, its use is limited to the super-user.
