in reply to Assist with code

Hi

What are you trying to do? From your code you just read in both files and print the lines in the second one that are not present in the first. But you talk about "add or append" and I don't see where you want to add or append the lines to.

Also if you just want to keep track of the lines already seen in the first file you don't need to use $i++ in the assigment to the hash, you can just put the value to a defined non-zero one (like '1').

It also helps readability if you use <code> .. </code> tags.

Cheers
