      Hmm, you’ve lost me as to where you are in the process as I can’t find “prefix” in anything I’ve pointed to…

        List 2 should be entered in the “secondary view” of Notepad++, example:

          Alright i have done the secondary view and downloaded the script that you published 19 hours ago. i tried it with only a couple thousand numbers and it took the program quite a while, but the program also marked all 9s that are in list 1, together with the numbers that are in list 2.

          here i’ve done a video about that:

            It wasn’t considered that numbers in the list could be part of larger numbers. Meaning that you probably have a line with only 9 on it in your list in the secondary view?

            A similar thing would happen if you had a line of 123 and in the main view you had 1234, 61235, 7891230, etc.

            We can work around that, but some other further experimentation has shown that this might not be a viable way to do what you need. I don’t think the script logic is flawed, but I don’t have time immediately to dig in deeper to see what is truly going on.

            In light of that I suppose I’d advise you to seek an alternate solution if your need is short-term. I’d really not like to see a non-Notepad++ solution worked out in this forum, because it is off-topic, but perhaps this one time is OK (because I feel bad taking you down the N++ road only to abort) if someone has time and wants to present one of those.

                @Alan-Kilborn i have found the 9, thank you. And i believe that everything worked now. How can i delete the numbers from FILE 1 in the final stage?

                  I’m amazed you didn’t encounter any of the “weirdness” I did.
                  But I suppose that is a good thing.
                  I have a “highly scripted” setup, so perhaps that is what is causing the weirdness I see when I was experimenting?

                  But, your next step should be to right-click where I have the red dot in the following (doesn’t have to be on line 6!, just in that same vertical “bookmark margin” area), and choose the indicated command:

                    thank you! hopefully there won’t be any problems when working with the millions of numbers but i would come back in that case. for now everything went super smoothly.

                      BTW, I would be very cautious before finishing up your task, that more things similar to the 9 problem discussed earlier, might have occurred. You should check on that; let me know, there’s an easy way to avoid that.

                        I got thinking more about how this problem would be better solved.
                        If we allow ourselves to dream about features that Notepad++ maybe itself should have, here’s how I think I’d solve it:

                        1. Add a delimiter line at the bottom of the file from which lines are to be removed from (delimiter line contains data that doesn’t otherwise occur in either file)
                        2. Paste all lines from the second file (containing the list of things to be removed from the first file), below the delimiter line in the first file
                        3. Choose Delete all non-unique lines from the Edit menu’s Line Operations submenu <— special note: fantasy Notepad++ feature that does not currently exist!!
                        4. Remove the delimiter line added earlier and any lines that remain after it

                        After that the first file would contain the desired data.

                        I’m fairly certain I’ve seen a “Delete all non-unique lines” (or maybe a “Keep only unique lines”) in a different editor, but I can’t for sure remember which one. Ultraedit? Hmm.

                        Anyway, we recently have had Delete Duplicate Lines functionality added, how about the addition of another new command?

                        @PeterJones Yep, don’t say it…I will…FEATURE REQUEST

                          Hello, @m-p, @peterjones, @alan-kilborn, @troshindv and All,

                          As @peterJones said, a simple regex S/R could work for moderate files size. But with files of 2,000,000 lines about, this S/R would probably be totally wrong because of the regex engine’s overflow issue :-((

                          But all is not lost ! The problem is that, in huge files, it may occur a very large gap between a line and its first duplicate one. This problem can, luckily, be eliminated by using these following steps :

                          • First, number all the lines

                          • Then, sort the lines in an ascending order

                          • Delete all lines which exist in more than 1 copy, which should be easy as these lines are, now, consecutive

                          • Re-sort all the remaining unique lines to restore their initial list order

                          Below, I’ll try to explain these steps with a short text. However, I quite confident that this method should work with huge lists, too, minus the necessary time, of course, to perform sorts and regex search/replacements !


                          Let’s go :

                          • From the license.txt file, I extracted only the non-blank lines and shortened the others to, roughly, their first 32 characters, ending with this 42-lines text :

                              Perhaps that regex-intensive solution becomes the defacto standard way of solving this problem.

                              But, it might be nice to see in Notepad++ itself, a command to “Remove lines from primary view tab that occur in secondary view tab”, or some such less-wordy verbage.

                                The volume of data dictates its own terms.
                                PS. It is better to wrap all actions in a macro.

                                  That doesn’t make sense as the solution crafted by @guy038 was specifically considering large “volumes”.

                                  I don’t believe @guy038 's solution can be made into a macro; can you explain how you think it can be?

                                    well, there were definitely some problems. LIST 1 has got 7.4mil number whilst LIST 2 got 1.2mil numbers. I believe that this is definitely too much to deal with. I’ll try the method of @guy038 now even though im not sure if i understood it all. Let’s try it at least

                                      Hello, @m-p, @peterjones, @alan-kilborn, @troshindv and All,

                                      Oh…! Indeed, dealing with two files of 7,400,000 and 1,200,000 lines is not an easy task ! So you will have to work with a 8,600,000 lines file : good luck !

                                      Do not hesitate to ask me for more information if you encounter difficulties in implementing my method !

                                      • First, I would advice you to repeat my own tiny example, first, to get its general idea

                                      • Regarding your real example, I would say that :

                                        • The N++ sort feature is very quick, in all cases

                                        • I suppose that the numbering operation, with the column editor, should not be very long, too !

                                        • May be, the first of the three regex S/R will probably take some time. Just be patient : it should work in the end !

                                      Best Regards

                                      guy038
