Ed Schouten b30bfd4339 Add a utility, utxrm(8).
Most of the ports I broke when I imported utmpx, were simple management
utilities for the utmp database, allowing you to add/remove entries
manually.

Add a small tool called utxrm(8), which allows you to remove an entry
from the utmpx database by hand. This is useful when a login daemon
crashes or fails to remove the entry during shutdown.

.Sh NAME
.Nm utxrm
.Nd remove sessions from the user accounting database
.Sh SYNOPSIS
.Nm
.Ar identifier
.Ar ...
.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.
.Sh SEE ALSO
.Xr getent 1 ,
.Xr w 1 ,
.Xr pututxline 3 .
.Sh HISTORY
The
.Nm
utility appeared in
.Fx 9.0 .
