### if the oscam config directory is not found, then use the "/tmp" directory, to avoid a possible error in the variable below:

#OSCAM_SRVID="/tmp/oscam_-_merged-kingofsat.srvid"
OSCAM_SRVID="${OSCAM_CFGDIR}/oscam.srvid"

### create temporary ".srvid" files

create_srvid_file "https://www.satelitnatv.sk/frekvencie/freesat-sk/" "FreeSAT" "0D97,0653,0B02"

### merge all generated ".srvid" files into one file + write this new file to the Oscam config-dir:
echo "$HEADER" > $OSCAM_SRVID
echo -e "### File creation date: $(date '+%Y-%m-%d %H:%M:%S')\n" >> $OSCAM_SRVID
cat /tmp/oscam__* >> $OSCAM_SRVID
