So at each $mismatch

I don't understand "being at a variable".

I will have a series of line extracted let's say 1000000 for $mismatch =1.

How do you determine how many lines to extract?

Then when mismatch changes to 2, another set of lines will be extracted. let's say 700000.

What causes $mismatch to change?

I will have a series of line extracted

I don't understand "extracting a line". Do you mean "reading a line"? What do with the lines you've extracted?
