seek works with byte positions; length counts characters. If your file is in text mode, a newline is two bytes on windows, but one byte on linux; it's one character in either case.

Technically, when your file is not in binary mode, you shouldn't pass anything to seek that's not the result of tell. So you might a) do a tell before you read the line, or b) binmode the file.
