Re^2: Reading concurrently two files with different number of lines

I don't think this would work as diff compares line by line. Meaning that if I have:

ABC a b
+ value=3.14
+ value2="name"
[download]

and

ABC a b
+ value="other"
+ value2="name"
[download]

Then I would have either 1 or 2 lines (depending if returning matched or unmatched lines), which is not what I want. I need to have the full 'line' (starting with a letter plus all the following starting by a +) if either of these are different.

Unless diff understands and deals with continuation lines, which in case I don't know that.

`diff` would not understand the continuation lines, but it doesn't necessarily have to. You can break your problem into two parts, and attack them individually: Normalize your inputs Compare your inputs The first you would do with Perl. Write a script that just handles the line continuations and normalizes your input into a "clean" format. You could then use `diff` to do the actual comparison between the two files. If `diff` doesn't meet your requirements for some reason, your comparison code would still be cleaner and simpler for not having to deal with the line continuations.

Thanks for the details. In the end, I already had my line to be compared in an array, so I just ended up using string comparison. I gave my "solution" below following my code working great here :)	[reply]
