42 Usage: $0 [-h|--help] [--sessions] [--sessdays DAYS] [-v|--verbose] [--zebraqueue DAYS] [-m|--mail] [--merged] [--import DAYS] [--logs DAYS]
44 -h --help prints this help message, and exits, ignoring all
46 --sessions purge the sessions table. If you use this while users
47 are logged into Koha, they will have to reconnect.
48 --sessdays DAYS purge only sessions older than DAYS days.
49 -v --verbose will cause the script to give you a bit more information
51 --zebraqueue DAYS purge completed zebraqueue entries older than DAYS days.
52 Defaults to 30 days if no days specified.
53 -m --mail DAYS purge items from the mail queue that are older than DAYS days.
54 Defaults to 30 days if no days specified.
55 --merged purged completed entries from need_merge_authorities.
56 --import DAYS purge records from import tables older than DAYS days.
57 Defaults to 60 days if no days specified.
58 --logs DAYS purge entries from action_logs older than DAYS days.
59 Defaults to 180 days if no days specified.
