So I'm working on a script that will pass arguments that are text files, and I should output the total amount of lines . Like if I say

./myScript file1 file2 file3 

it will print

10 total

(let us assume that the sum of all the lines from those three files is 10)

I know how to go over all the arguments, I also know that to get the amount of lines in a file, I would say:

wc -l < fileName 

However how can I make that into an "int" that I can add to some sort of cumulative sum? Thanks friends
