Greetings, I'm trying to figure out a grep pattern to search for blocks of contiguous duplicate lines and eliminate the duplicate. Example:
text A text A text 1 text 2 text 3 text 1 text 2 text 3 text I text A After processing, the file should read text A text 1 text 2 text 3 text I text A The actual text is hard wrapped paragraphs, and the lines vary from ~5 to 90 characters long (or thereabouts). There is white space (3 or more spaces, as illustrated above) at the beginning of populated lines. There can be blank lines (just a return) or white space lines (lines with only space characters terminated by a return), but they should be considered of equal status as populated lines (i.e. when identifying duplicate blocks, white space is consistent and important). My current attempt is: (?s)(^.+)\1 but that matches consecutive characters at the beginning of lines in addition to desired duplicate blocks. Is there a modification to this (or another approach) that could make it only compare complete lines? Thanks for any assistance you can offer. - Todd P.S.
