json - 如何使用 jq 解析 json 对象数组

Question

我需要解析一个包含很多数组的 Json 文件。

这是json源：

{
"iabVersion": "IAB_V2",
"categories": [{
    "categories": [{
        "categories": [{
            "id": "1.1.1",
            "name": "Commercial Trucks"
        },
        {
            "id": "1.1.2",
            "name": "Convertible"
        },
        {
            "id": "1.1.3",
            "name": "Coupe"
        },
        {
            "id": "1.1.4",
            "name": "Crossover"
        },
        {
            "id": "1.1.5",
            "name": "Hatchback"
        },
        {
            "id": "1.1.6",
            "name": "Microcar"
        },
        {
            "id": "1.1.7",
            "name": "Minivan"
        },
        {
            "id": "1.1.8",
            "name": "Off-Road Vehicles"
        },
        {
            "id": "1.1.9",
            "name": "Pickup Trucks"
        },
        {
            "id": "1.1.10",
            "name": "Sedan"
        },
        {
            "id": "1.1.11",
            "name": "Station Wagon"
        },
        {
            "id": "1.1.12",
            "name": "SUV"
        },
        {
            "id": "1.1.13",
            "name": "Van"
        }],
        "id": "1.1",
        "name": "Auto Body Styles"
    }
  }
}

这是所需的json：

{
"id": "1.1.1",
"name": "Commercial Trucks"
}
{
"id": "1.1.2",
"name": "Convertible"
}

如何通过 jq 解析它？

假设 JSON 输入已经更正，下面的 jq 过滤器似乎满足要求，例如：

.categories[].categories[].categories[]

这会产生一个 JSON 对象流，开始：

{
  "id": "1.1.1",
  "name": "Commercial Trucks"
}
{
  "id": "1.1.2",
  "name": "Convertible"
}
