That was really quick. Many thanks
One last question though i should have asked it earlier.
"i" does it represent the line or line counter, bit confused as you were again using to assign the value to variables u,e

i represents each field in your record separated by blank space (by default).

NF represents the number of fields or the last field, using for loop you are going through each field (incrementing i) until last field (NF) is reached.

One way is to pipe the output of this awk program to a while loop, read them and assign to shell variable.

Or you can rewrite the whole program in bash instead of awk.
