Because the 4th and the 5th column has A G for both File1 and 2. If File1 has A G at 4th and at 5th column, then I want to select only those which as A A or G G in File2. The logic is if in File 1, there is "X" in column 4 and "Y" in column 5, I want to select only those which has "X" "X" or "Y" "Y" in File 2 at 4th and 5th column.
