    [RegEx] [Notepad++] Delete all similar 1st 3 characters string lines


    Hello guys!

    I am trying to delete lines with similar first 3 characters using RegEx

    I figured out this:

    ((?<=\n)|^)([^\n]{3})([^\n]\n)(.\n)?\2[^\n]*($|\n)

    However, it marks only 1 duplicate.

    How to let it mark all the other duplicates?

    Can somebody please fix the RegEx?

    Thanks in advance!

    Regards,

    A good example would be if I have these text:
    Code:
    abcd
    abce
    abcg
    ebgf
    ebsf
    I should select "abcd" "abce" "abcg" and mark them and delete them not only the first instance "abcd"
