別の要素をキーとしてJSON要素を取得する方法は？

優秀のようなホストIDが含まれている必要があり、我々はあなたが望むものを知っています。さて、あなたはどの言語で働いていますか、何を試しましたか？ – JAAulde

これを行うにはシェルスクリプトを使用しています。 –

items.forEach(function(item) { 
    if (/* item.name HIVE regex */) answerArr.push(item.hostRef.hostId);

シェルスクリプトを使用して何かを提案できますか？ –

配列の反復処理に相当するシェルスクリプトを記述し、特定のフィールドで正規表現を実行し、正規表現が真であればオブジェクトから値を格納します。 – Russbear
