No, I just put a dash there temporarily so I can then extract all the lines that contain it.

It doesn't even matter what symbol. (could be a "!,@,$, etc...). It's just added to the lines I do want so there is something that all the lines I want have in common - and therefore be used to be extracted.

So no it's not what I'm looking for in my end result or anything.

Once I do get all the ones I want in front of me, with a no longer needed dash in front of every one: I have another online tool that instantly gets rid of all the dashes. So that's not a problem.
