but note that nothing in this script sets DEST

Note also that in another thread you said you wanted the output to use a tab instead of comma to separate output fields. Your output field separator is actually a command and a space. To use tab instead change:

Code:

done < "$SRC" | awk 'ORS=NR%2?", ":RS' > $DEST

to:

Code:

done < "$SRC" | awk 'ORS=NR%2?"\t":RS' > $DEST
