Filter-Media script can run either individually after submission of an item for the instant result. Apply the following command to run filter-media,

sudo /dspace/bin/dspace filter-media

The filter-Media command can be added to Crontab to schedule the filter-media command. Add these cron settings under the Linux user account which is running Tomcat (and owns the dspace installation directory).

If the DSpace run on a 24x7 working server machine, add the following entries into the Crontab,

# Run the media filter at 03:00 am every day.
