This script lets you manage the indexer daemon for your Koha instances.

Usage:

$scriptname [--start|--stop|--restart] [--quiet|-q] instancename1 [instancename2...]

$scriptname -h|--help

    --start               Start the indexer daemon for the specified instances

    --stop                Stop the indexer daemon for the specified instances

    --restart             Restart the indexer daemon for the specified instances

    --quiet|-q            Make the script quiet about non existent instance names

    --help|-h             Display this help message
