[Koha] Reservoir records deletion

[Mark Alexander]

> I want to delete all biblio records from my koha but they are still appearing in reservoir. How to remove them? I have deleted them from catalogue and they are not imported so I cant clean the batch.

This is how I did it:

  koha-shell LIB  # LIB is your Koha instance name
  /usr/share/koha/bin/cronjobs/cleanup_database.pl --import 60 -v

Here is what the --help option says about this:

   --import DAYS      purge records from import tables older than DAYS days.
                      Defaults to 60 days if no days specified.
