Simple duplicate lines GREP deletion

[Gioyer07]

Although much already has been explained here about merging page numbers and duplicated lines, I can't figure out a simple syntax to eliminate a duplicated line as:

011500875 16

011500875 17

011500875 17

011500875 17

011500875 18
(where the structure is:

011500875 ^y17^p)

Thanks for help

There are a lot of GREP questions already answered about this in this very forum. Notice how many show up on the right hand side of this forum screen that appear to answer your question. Maybe this one?

Thank you. Yes you are right. I apologize but somehow my research returned only more complex cases and didn't get to the post you linked. Will refine my search criteria when facing next issue.

To be more precise, I saw the post you linked before posting anything. It is way different from my need, much more complex, how to reduce this to my issue is beyond my knowledge. So I made the question with screenshot. Thanks.

Why is this double post necessary?
Have you even tried the answer I gave you in your other thread?

To remove one following duplicate you can try something like that:

(\d+~y\d+\r)\K\1

if numbers tab numbers end of paragraph

If that does not work - please show a screenshot with visible hidden characters.

Hello. Thank also here and again sorry for the delayed reply. This was the first attempt I made to get help. I faced the fact that nobody gave an answer in a couple of days. I thought that post was not clear enough. Looked how to delete it but couldn't find. So I made a new post and provided a screenshot. In the meanwhile I had a technical problem in my office's computer and could not promptly check and reply. I really thank you and the community for this online service, I can believe it's a hard work to keep it "clean".
