Posted at

こんなJSONの中から特定のキーだけ取得したJSONを再作成する

sample.json
{
    "userList": [
        {
            "userID": 1,
            "nickname": "taro",
            "height": 175.7,
            "_disabled": false
        },
        {
            "userID": 3,
            "nickname": "hanoko",
            "_disabled": false
        },
        {
            "userID": 4,
            "nickname": "momoko",
            "weight": 45,
            "_disabled": true
        }
    ]
}

userIDと_disabledだけ取得

$ cat sample.json | jq -r '{userList: [.userList[] | { userID: .userID, _disabled: ._disabled}]}'
{
  "userList": [
    {
      "userID": 1,
      "_disabled": false
    },
    {
      "userID": 3,
      "_disabled": false
    },
    {
      "userID": 4,
      "_disabled": true
    }
  ]
}
