|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
utility can be used to 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
|
||
|
|
Because this utility requires write-access to the user accounting
|
||
|
|
database, its use is limited to the super-user.
