  • Are you sure that hunspell-en exists? Anyway, you can use apt-cache policy and grep for ^$PACKAGENAME:. Commented Dec 26, 2017 at 23:02
  • @AlexP these are only examples hunspell-en does not exist because they package with country names, hunspell-ar does exist and there are no country-name packages. I need to find the most accurate package for a given country and language. Commented Dec 26, 2017 at 23:03

    find is just like apt-cache in this respect - useless return code, success is based on output. Commented Dec 27, 2017 at 3:00

    Yes, I agree they're both stemming from the same problem. The chosen answer mentions there mentions -z which sadly isn't a solution here so the use-case-specific problem isn't applicable. And there is no mention of an idiom or constructing a pipeline without using null-termination (not an option on apt-cache) Commented Dec 27, 2017 at 3:21

    @EvanCarroll the null termination is entirely optional. I only used it because it's the safest way to deal with filenames, so one would expect find to be used with -print0 and so grep with -z. Since apt-cache isn't giving null-terminated output, you don't need -z. Commented Dec 27, 2017 at 3:55
