Hi,

Is it possible to output symbols which constitute non-matched parts of text=
? For instance, I expect

printf "banana\napple" | grep --invert-match --only-matching '=
;ban'

to produce

ana
apple

or

apple

, but it doesn't produce anything.

I need -o because I grep multiline pattern with -z.

Unfortunately the -v and -o options don't currently combine in that way. Perhaps they should, or perhaps another option could be added to do what you want. I'll mark this as a wishlist item.
