Following may help you in same, let me know if you have any queries. EDIT: For your question setting FS before the value of array named T because while printing them(which will happen while file2 is being read) we are not giving the field separator there and as per your requirement we need it so that is why we are doing this, also one benefit of this approach is if $1 of file2 is not present in file1 so it will NOT simply print field separator, which is not your requirement.
Thanks,
