Select 不同级别的多个字段

Question

我有一个 .json 文件，看起来像 :

[
    {
        "network": "X.X.X.1",
        "defaultGateway": "X.X.X.X",
        "ipAddressTab": [
            {
                "foo1": "10.0.0.1",
                "foo2": "network",
                "foo3": "reserved",
                "foo4": null,
                "foo5": null,
                "foo6": null,
                "foo7": null,
                "foo8": null,
                "foo9": null,
                "foo10": null,
                "foo11": null
            },
            {
                "foo1": "10.0.0.2",
                "foo2": "network",
                "foo3": "reserved",
                "foo4": null,

                "foo7": null,
                "foo8": null,
                "foo9": null,
                "foo10": null,
                "foo11": null
            },
            {
                "foo1": "10.0.0.3",
                "foo2": "network",
                "foo3": "reserved",

                "foo11": null
             },
             {
                "foo1": "10.0.0.4",
                "foo3": "available"
             },
             {

                "foo3": "available"
             },
             {
                "foo1": "10.0.0.6",
                "foo3": "available"
             },
             {
                "foo1": "10.0.0.7",
                "foo3": "available"
             }
        ],
        "full": false,
        "id": "xxx"
    },
     {
        "network": "X.X.X.2",
        "defaultGateway": "X.X.X.X",
        "ipAddressTab": [
            {
                "foo1": "10.0.0.1",
                "foo2": "network",
                "foo3": "reserved",
                "foo4": null,
                "foo5": null,

                "foo7": null,

                "foo10": null,
                "foo11": null
            },
            {
                "foo1": "10.0.0.2",
                "foo2": "network",
                "foo3": "reserved",
                "foo4": null,
                "foo5": null,
                "foo6": null,
                "foo7": null,
                "foo8": null,
                "foo9": null,
                "foo10": null,
                "foo11": null
            },
            {
                "foo1": "10.0.0.3",
                "foo2": "network",
                "foo3": "reserved",
                "foo4": null,
                "foo5": null,

                "foo7": null,

                "foo10": null,
                "foo11": null
             },
             {
                "foo1": "10.0.0.4",
                "foo3": "available"
             },
             {   
                "foo1": "10.0.0.5",
                "foo3": "available"
             },
             {
                "foo1": "10.0.0.6",
                "foo3": "available"
             },
             {
                "foo1": "10.0.0.7",
                "foo3": "available"
             }
        ],
        "full": false,
        "id": "xxx"
    }
]

我尝试的第一件事就是像这样显示每个元素：

cat myfile.txt | jq '.[]| {network: .network, ipAddressTab: .ipAddressTab}'

显示文件的每一行。

现在，我想显示一些行：

网络
ipAddressTab
foo1
foo3

   {
        "network": "X.X.X.1",
        "ipAddressTab": [
            {
                "foo1": "10.0.0.1",
                "foo3": "reserved",
           
                "foo1": "10.0.0.2",
                "foo3": "reserved",
            
                "foo1": "10.0.0.3",
                "foo3": "reserved",
             
                "foo1": "10.0.0.4",
                "foo3": "available"
             
                "foo1": "10.0.0.5",
                "foo3": "available"
            
                "foo1": "10.0.0.6",
                "foo3": "available"
            
                "foo1": "10.0.0.7",
                "foo3": "available"
             }
        ],
        "full": false,
    },
     {
        "network": "X.X.X.2",
        "ipAddressTab": [
            {
                "foo1": "10.0.0.1",
                "foo3": "reserved",
           
                "foo1": "10.0.0.2",
                "foo3": "reserved",
          
                "foo1": "10.0.0.3",
                "foo3": "reserved",
            
                "foo1": "10.0.0.4",
                "foo3": "available"
             
                "foo1": "10.0.0.5",
                "foo3": "available"
          
                "foo1": "10.0.0.6",
                "foo3": "available"

                "foo1": "10.0.0.7",
                "foo3": "available"
             }
        ],
        "full": false,
    }
]

我试过类似的东西：

cat myfile.txt | jq '.[]| {network: .network, ipAddressTab: .ipAddressTab(.foo1, .foo3)}'
cat myfile.txt | jq '.[]| {network: .network, ipAddressTab: .ipAddressTab[.foo1, .foo3]}'

但是没用！

谁能告诉我如何显示我需要的每个元素？

非常感谢！

Answer 1

首先select字段，然后修改ipAddressTab。

map({network, ipAddressTab, full}
    | .ipAddressTab[] |= {foo1, foo3})

^{Online demo}

Select 不同级别的多个字段

Select multiple fields at different levels

json

projection

jq
