        ok, but why results are inconsistent (with large datasets)?

        Various reasons, sometimes a regular expression approach to this needs to be refined to match the data better before it works well. If you search up some other threads on this topic you can trace through the evolution of a regex approach on certain datasets. However, I suspect you just want to get a workable solution and move on…and I fully endorse that. I’m tired of trying to use regex for this kind of thing. :)

        BTW, @Claudia-Frank going the extra mile…installing UE trial version just to track this down…nice!

          … boots are made for walking … :-)

          I’m confused about how UE does sort and delete duplicates.
          Used default settings.

          Only sorting

          Sorting and deleting duplicates

          There is obviously something wrong about UEs algorithm, isn’t it?
          And the version I used cut the list to 63732 lines.

          Cheers

                so the issue is: which result is the correct?

                  Hello, @patrickdrd, and All,

                  First of all, I quite pleased to be back on our N++ forum ! Indeed, I was away because of a general failure of my laptop hard drive C:, which, you could imagine, highly annoyed me and needed immediate care :-(((

                  So, after more than a week, a software purchase of EaseUS Recovery Wizard to restore my data ( the only one which could identify all my files, although Windows could not see the C: partition ), the fact that my first 32 Gb USB key did not work, either, ( Windows cannot format it !!), the re-install of the system on an other hard-disk, the Services Pack, the .NET versions, the different updates, some software installations and the total re-organization of my data structure, I can, now, close that bloody sub-routine !! ( Just note that, if I haven’t been able to get all my files back, I still had a last general backup, performed on the 04/13/18 )


                  Now, @patrickdrd, you said, in a post above :

                  guy038 regular expression results in 28109 lines

                  So, I download the list, from your link, in a new N++ tab :

                  https://easylist.to/easylist/easylist.txt

                  Notice that I, personally, found 69889 lines

                  Now, without any change on that text, I simply performed a sort with the N++ command Edit > Line Operations > Sort Lines Lexicographically Ascending, on that raw text

                  Then, I used the regex S/R, that I spoke in my previous post :

                  SEARCH : (?-s)(^.+\R)\1+

                  REPLACE : \1

                  I obtained a file of 69790 lines => The difference of 99 lines ( the duplicate ones ) were suppressed, almost immediately !

                  So, may be, I’m missing something ?

                  Cheers,

                  guy038

                    I can’t say for sure, is there any tool that can tell us how many the unique lines are?

                      Ok - the difference of the total amount of lines in TextFX /python and regex
                      can be explained, the different usage of caseing(not sure if this is the right word).

                      Regex search/replace is insensitive whereas python script is sensitive.
                      Once we use the same, the result is the same.

                      For the provided example list, I assume, insensitive search and deletion is ok
                      but for other cases, sensitive search/replaces might be important.

                      Btw. I also used sort and uniq command line tools from linux with same results as python and regex.

                      Cheers
                      Claudia

                        thanks for clarifying, in terms of speed?

                        can python script be made to ignore case?

                        I want to ignore case and I want it fast (useful for large files) too

                            yes

                            I want to ignore case

                            Understood! :-D

                            and I want it fast (useful for large files) too

                            Ok, so what is “fast”? PS is in general going to be slower than some other methods, but unless you sort “large files”–also not well defined-- constantly why is speed all that important?

                            As an example, I took @Claudia-Frank 's PS one-liner above and ran it on the “easylist” data file, and for me it took 3.94 seconds…would that be defined as “fast” or “slow” or…?

                            And on the topic of “large” files, when you get too large (which honestly isn’t really big) you get into trouble with Notepad++ itself dealing with the files…

                              yes, with python we could do almost everything :-D

                              Is it important to keep the original lines untouched?
                              I mean, having two lines like

                              Test_line_content
                              test_Line_content
                              

                              could result in either

                              test_line_content
                              

                              or

                              Test_line_content
                              

                              I will post a performance optimized script later today.

                                3.94 for a 60k lines file is ok,
                                I mean I show much more time needed, if I remember correctly it should be with regular expressions

                                sorting is ok too, I want them sorted each time, if that’s what you ask scott

                                @claudia, if possible, make them “accent insensitive” too

                                  sorry, don’t know the term “accent insensitive” , what does it mean?
                                  For example that è is the same as e?

                                  Can you provide example data (just need a couple of lines) to see if it is working correctly?

                                    I can envision the following specification for a general purpose script (goes beyond what @patrickdrd has asked for):

                                    • sort lines case sensitive, keep duplicate lines
                                    • sort lines case sensitive, remove duplicate lines
                                    • sort lines case sensitive, keep duplicate lines, reverse order on the sort
                                    • sort lines case sensitive, remove duplicate lines, reverse order on the sort
                                    • sort lines case insensitive, keep duplicate lines
                                    • sort lines case insensitive, remove duplicate lines
                                    • sort lines case insensitive, keep duplicate lines, reverse order on the sort
                                    • sort lines case insensitive, remove duplicate lines, reverse order on the sort
                                    • no sort, remove duplicate lines (case sensitive)
                                    • no sort, remove duplicate lines (case insensitive)

                                    A selection active when invoking should define:

                                    • lines to be affected (only those touched by selection vertically); act on all lines if no selection
                                    • columns to be used as the sort key (if rectangular selection use the selected columns as the sort key; if zero-width rect selection consider the key to start at the selection column out to the end of the variable-length lines)

                                    Probably I’ve forgotten something important to this “sort” of thing…

                                    :-D

                                          …the following spec…

                                          Hey Scott! You did forget some things! How about when removing duplicates, we need the options to:

                                          • keep one occurrence of a duplicated line (when sorting)
                                          • keep no occurrences of a duplicated line (when sorting or not sorting)
                                          • keep LAST occurrence of a duplicated line (when not sorting)
                                          • keep FIRST occurrence of a duplicated line (when not sorting)
