This option would act like -o, except it would omit all the line contents instead of just the non-matching part. Seems like a bit of a specialized use, though. Can't you get something close to what you want, by asking the editor to search for the matching lines? For vi, you can do the following, and I assume your editor has a similar option: vi +/PATTERN $(grep -l PATTERN FILES)
