huh, I'm not sure. I played with it a little and here's another
problem
here is some testing
data processor
will return 'testingdata' because the newlines get stripped out
leaving no space between the words. so..
first, replace all '-\n' with '' so we dehyphenate any hyphenated
words split by a newline. there will be some words that should be
hyphenated but lose that hyphen, however, I think that's probably a
pretty rare case and it ignores any mid-line hyphenated words. also
makes it easier to grep as we can ignore the hyphens in processor next
replace all '\n' with ' ' so that we avoid the above problem. then
replace any single-or-more occurance of ' ' with '\n' to split the
words into seperate lines and finally grep away.
tr -d '-\n' <IN | tr '\n' ' ' | tr -s ' ' '\n' | grep -B1 'Processor'
| grep -v 'Processor\|--'

there must be more. I haven't seen any perl junkies provide us with
some permutation of ($*&#^&*%^^@@Processor%^&^$%^%#$&^$%*&^% that
spits the answer right out. ^^^^----- that's not perl code BTW, just
random shifted number-row. but it looks like perl eh? hehe
