in thread diff not working as it should

Play with the STYLE option, or simply apply a grep or a regexp m!(^\|\||^\*)! to the output line by line

Re^4: diff not working as it should

    Not seeing much on the STYLE option.
    I can use the regex m/(^\*)/ and that gives me what I need for the most part.
    But where in the code can I use this regex? That is, can it be used as part of the diff command, as in { sub (m/(^\*)/) } ? (yes, I know this is not syntactically correct but you get the idea.)
    Cheers!

      you have two lines of code, so it should be easy to choose... start just in the third line

      open the output file
enter a loop reading line by line
print only the matching lines
close and reopen 
send it again to the file
and you have it.

        Yes, I understand -- and have gone ahead -- and did the regex with some extra code after the diff(). And I thank you for your input.
        I was just wondering if there was some way to do the regex within the diff command or diff command options (I don't see anything at first glance.)
        Cheers!
