jq：json 个对象的输出数组

Question

假设我有输入：

{
    "name": "John",
    "email": "john@company.com"
}
{
    "name": "Brad",
    "email": "brad@company.com"
}

如何获得输出：

[
    {
        "name": "John",
        "email": "john@company.com"
    },
    {
        "name": "Brad",
        "email": "brad@company.com"
    }
]

我都试过了：

jq '[. | {name, email}]'

和

jq '. | [{name, email}]'

这两个都给了我输出

[
    {
        "name": "John",
        "email": "john@company.com"
    }
]
[
    {
        "name": "Brad",
        "email": "brad@company.com"
    }
]

我在文档中也没有看到数组输出的选项，感谢任何帮助

使用 slurp 模式：

  o   --slurp/-s:

      Instead of running the filter for each JSON object
      in the input, read the entire input stream into a large
      array and run the filter just once.

$ jq -s '.' < tmp.json
[
  {
    "name": "John",
    "email": "john@company.com"
  },
  {
    "name": "Brad",
    "email": "brad@company.com"
  }
]
