Yes, that's cool! First slurp, then split on paragraph chunks, and finally simply match against keywords in the block. That's nice. Could you have not done that without the zero-width positive look-behind? Seems like that would be the best way, but I still wonder...

    You could simplify the split to \n\n+ or something similar, but then you need to modify something else to keep the records newline separated. I'm willing to go to pretty extreme lengths to keep print if /RAM socket/ && !/Not Installed/ clean just because of personal taste. TIMTOWTDI.

    dmidecode | perl -e 'undef $/;/RAM socket/ && !/Not Installed/ && s/$/\n\n/ && print for split /\n\n+/, <>'


    #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

      That's another good example. Less clear than your first, but still much less ugly than my original line-by-line cherry picker.
