Select row and element in awk

Question

I learned that in awk, $2 is the 2nd column. How to specify the ith line and the element at the ith row and jth column?

Answer 1

To expand on Dennis's answer, use awk's -v option to pass the i and j values:

# print the j'th field of the i'th line
awk -v i=5 -v j=3 'FNR == i {print $j}'
