In jq, I can select an item in a list fairly easily:
$ echo \'[\"a\",\"b\",\"c\",\"d\",\"e\"]\' | jq \'.[] | select(. == (\"a\",\"c\"))\'
I'm sure it is not the most simple solution, but it works :)
$ echo '["a","b","c","d","e"]' | jq '.[] | select(test("[^ac]"))'
Edit: one more solution - this is even worse :)
$ echo '["a","b","c","d","e"]' | jq '.[] | select(. != ("a") and . != ("b"))'
