## Topic Body

- JSON 데이터를 경로구조로 바꿔서 grep 했을때 위치를 쉽게 알 수 있음

- 추출한 경로구조 데이터만 다시 JSON으로 바꾸는 것도 지원

- 배열의 경우 인덱스도 표시

▶ gron "https://api.github.com/repos/tomnomnom/gron/commits?per_page=1" | fgrep "commit.author"

json[0].commit.author = {};

json[0].commit.author.date = "2016-07-02T10:51:21Z";

json[0].commit.author.email = "mail@tomnomnom.com";

json[0].commit.author.name = "Tom Hudson";

▶ gron "https://api.github.com/repos/tomnomnom/gron/commits?per_page=1" | fgrep "commit.author" | gron --ungron
