Suggestion - there must be an observable pattern to this, not just line numbers. We would have to have a huge list of line numbers, or try to calculate offsets to attempt what you ask as it stands.
Using patterns allows for things like, 'Oops, the first line to delete is not 62 but 63 lines from the top'. In other words, you applied some kind of logic to your data. To do this in a reasonable way we need to understand the layout and logic behind it.
Alternatively, you need to generate a file that is made of ranges of line numbers and verify there are no Oops moments in there. Otherwise it is likely this exercise will turn your file into hash. You don't want to have to verify 50000 lines by hand. And if verification is simple - that means there is a pattern we can use.
