jsonデータを整形・絞り込みできるjqコマンドをmacOSにインストールしたかったので、HomeBrewでインストールしてみました。
インストール
以下を実行します。
$ brew install jq
実行時のログは以下の様な感じでした

サンプル的に試してみる
例えば、以下の郵便番号による住所検索 API
を curl で実行して、それを jq コマンドにパイプで渡してみます（queryパラメータの postal に指定している値が郵便番号）
curl "http://geoapi.heartrails.com/api/json?method=searchByPostal&postal=1060032" | jq
実行してみると以下のようになります。
$ curl "http://geoapi.heartrails.com/api/json?method=searchByPostal&postal=1060032" | jq % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 1882 0 1882 0 0 59882 0 --:--:-- --:--:-- --:--:-- 60709 { "response": { "location": [ { "city": "港区", "city_kana": "みなとく", "town": "六本木一丁目", "town_kana": "ろっぽんぎ1ちょうめ", "x": "139.740991", "y": "35.665082", "prefecture": "東京都", "postal": "1060032" }, { "city": "港区", "city_kana": "みなとく", "town": "六本木二丁目", "town_kana": "ろっぽんぎ2ちょうめ", "x": "139.737087", "y": "35.666974", "prefecture": "東京都", "postal": "1060032" }, { "city": "港区", "city_kana": "みなとく", "town": "六本木三丁目", "town_kana": "ろっぽんぎ3ちょうめ", "x": "139.735452", "y": "35.663977", "prefecture": "東京都", "postal": "1060032" }, { "city": "港区", "city_kana": "みなとく", "town": "六本木四丁目", "town_kana": "ろっぽんぎ4ちょうめ", "x": "139.733837", "y": "35.665489", "prefecture": "東京都", "postal": "1060032" }, { "city": "港区", "city_kana": "みなとく", "town": "六本木五丁目", "town_kana": "ろっぽんぎ5ちょうめ", "x": "139.735248", "y": "35.658358", "prefecture": "東京都", "postal": "1060032" }, { "city": "港区", "city_kana": "みなとく", "town": "六本木六丁目", "town_kana": "ろっぽんぎ6ちょうめ", "x": "139.729932", "y": "35.659856", "prefecture": "東京都", "postal": "1060032" }, { "city": "港区", "city_kana": "みなとく", "town": "六本木七丁目", "town_kana": "ろっぽんぎ7ちょうめ", "x": "139.726863", "y": "35.664751", "prefecture": "東京都", "postal": "1060032" } ] } }
これだけで、JSONを見やすく整形した状態で出力してくれます
jq コマンドは、かなり色々とできるはずなので、使い方調べながらもっと使いこなせるようになりたいです。
