#!/bin/sh


#### shell-script to download userbouquet file from the internet, and then overwrite local userbouquet file - if both files are different (tested for file content differences)


#### it isn't based on "init 4" and "init 3" commands to fast restart of Enigma2 (as the most reliable method for all Enigma distributions),
#### but it is based on the OpenWebif reload services !!!


#### CRON config example - check and download new userbouquet file - every day, at 05:15 :
####      15 05 * * *        /bin/sh -c "/usr/script/bouquetx.sh download"
