object - 将几个对象与 jq slurp 合并在一起而不覆盖重复键

Question

我有这两个 json 文件:
ubuntubionic.json :

  {
    "ubuntu": {
      "os_ver": "bionic",
      "image": "abcdef",
      "image_tag": "3.33.3",
      "docker_compiler_image": "abc",
      "image_compiler_tag": "4.44.4"
    }
  }

和 ubuntufocal.json :

cat ubuntubionic.json
  {
    "ubuntu": {
      "os_ver": "focal",
      "image": "xxxx",
      "image_tag": "3.33.3",
      "docker_compiler_image": "xxxx",
      "image_compiler_tag": "4.44.4"
    }
  }`

我想将这两个文件合并为 1 个文件以获得如下所示的输出:

{
    "ubuntu": {
      "os_ver": "focal",
      "image": "abcdef",
      "image_tag": "3.33.3",
      "docker_compiler_image": "abc",
      "image_compiler_tag": "4.44.4"
    },
      "os_ver": "bionic",
      "image": "xxxx",
      "image_tag": "3.33.3",
      "docker_compiler_image": "xxxx",
      "image_compiler_tag": "4.44.4"

  }

我试过 jq -s 添加 ubuntufocal.json ubuntubionic.json > all_os.json
但我知道仿生正在覆盖焦点

cat all_os.json
{
  "ubuntu": {
    "os_ver": "bionic",
    "image": "xxxx",
    "image_tag": "3.33.3",
    "docker_compiler_image": "xxxx",
    "image_compiler_tag": "4.44.4"
  }
}

如何解决？完全迷失在 JQ 手册页中

要使其成为文件内容的数组，您不需要 add内置为 -s flag 已经将它们放在一个数组中

jq -s . ubuntubionic.json ubuntufocal.json

[
  {
    "ubuntu": {
      "os_ver": "bionic",
      "image": "abcdef",
      "image_tag": "3.33.3",
      "docker_compiler_image": "abc",
      "image_compiler_tag": "4.44.4"
    }
  },
  {
    "ubuntu": {
      "os_ver": "focal",
      "image": "xxxx",
      "image_tag": "3.33.3",
      "docker_compiler_image": "xxxx",
      "image_compiler_tag": "4.44.4"
    }
  }
]

如果要拔出ubuntu字段名称，并将每个对象的值(恰好也是对象)合并到一个数组中，也使用 map内置:

jq -s '{ubuntu: map(.ubuntu)}' ubuntubionic.json ubuntufocal.json

或者

jq -s '{ubuntu: map(add)}' ubuntubionic.json ubuntufocal.json

{
  "ubuntu": [
    {
      "os_ver": "bionic",
      "image": "abcdef",
      "image_tag": "3.33.3",
      "docker_compiler_image": "abc",
      "image_compiler_tag": "4.44.4"
    },
    {
      "os_ver": "focal",
      "image": "xxxx",
      "image_tag": "3.33.3",
      "docker_compiler_image": "xxxx",
      "image_compiler_tag": "4.44.4"
    }
  ]
}
