i want to find duplicate rows in a large txt file and save them(not delete them). can you help me ?
Do you need to keep them in their original order, or can they (the duplicate lines) be sorted by the technique that would allow you to copy only them?
no it’s not necessary to be in any order
Hello Νικόλαος Κερασιώτης,
If so, just refer to the post, below :
This post shows TWO methods :
A first one which does not keep the original order of the lines
A second one, much longer, but that will keep the original order of the lines
From what you replied to Scott, I suppose that the cases
METHOD 1section should be convenient to you :-))
