39.Ar ...
40.Sh DESCRIPTION
41The
42.Nm
43utility can be used to perform operations on the user accounting
44database, as done by
45.Xr pututxline 3 .
46.Pp
47The first argument to
48.Nm
49indicates an action to be performed:
50.Bl -tag -width ".Cm shutdown"
51.It Cm boot
52Write a boot time record to the user accounting database.
53This option should typically only be used by
54.Xr rc 8 .
55.It Cm shutdown
56Write a shutdown time record to the user accounting database.
57This option should typically only be used by
58.Xr rc 8 .
59.It Cm rm
60Remove stale sessions from the user accounting
61database, by referring to their
62.Ar identifier .
63Stale sessions can occur if a login service exits prematurely or fails
64to remove the session from the accounting database.
65.Pp
66Utilities such as
67.Xr w 1
68will not display the identifier corresponding with a login session,
69since its value is typically only of use by the process managing the
70record.
71The following command can be used to obtain all records from the user
72accounting database's active session table, including its identifiers:
73.Pp
74.Dl getent utmpx active
75.Pp
76Identifiers can either be supplied in hexadecimal form as displayed by
77.Xr getent 1 ,
78or as a string if the identifier allows such a representation.
79.El
80.Pp
81Because this utility requires write-access to the user accounting
82database, its use is limited to the super-user.
