SYNOPSIS

utx boot utx shutdown utx rm identifier ... utxrm 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.

To remain backward compatible, this action can also be invoked directly by using the utxrm command.

Because this utility requires write-access to the user accounting database, its use is limited to the super-user.
