$0: Remove unused authority records
|
|
|
|
This script removes authority records that do not have any biblio
|
|
records attached to them.
|
|
|
|
If the --aut option is supplied, only authority records of that
|
|
particular type will be checked for usage. --aut can be repeated.
|
|
|
|
If --aut is not supplied, all authority records will be checked.
|
|
|
|
Use --test to perform a test run. This script does not ask the
|
|
operator to confirm the deletion of each authority record.
|
|
|
|
parameters
|
|
--aut|authtypecode TYPE the list of authtypes to check
|
|
--test or -t test mode, don't delete really, just count
|
|
--help or -h show this message.
