jqを介してJSON形式のデータから一部のデータを取得する

JSON形式のサンプルデータがあります。

[
{
    "info":{
        "disk_num":"2",
        "hostname":"hostA",
        "net":[
            "eth0",
            "eth1"
        ],
        "software":{
            "version":"1.0.0",
            "build_date":"2021-10-08",
            "commit":"bfdaee"
        },
        "kernel":"5.0.0"
    },
    "ip":"10.240.82.192",
    "status":"PASS"
},
{
    "info":{
        "disk_num":"2",
        "hostname":"hostA",
        "net":[
            "eth0",
            "eth1"
        ],
        "software":{
            "version":"1.0.0",
            "build_date":"2021-10-08",
            "commit":"bfdaee"
        },
        "kernel":"5.0.3"
    },
    "ip":"10.240.82.193",
    "status":"PASS"
},
{
    "info":{
        "disk_num":"5",
        "hostname":"hostB",
        "net":[
            "eth0",
            "eth1"
        ],
        "software":{
            "version":"1.0.2",
            "build_date":"2021-10-11",
            "commit":"935678"
        },
        "kernel":"5.0.1"
    },
    "ip":"10.240.82.194",
    "status":"PASS"
}
]

部分データを取得して別のjson FORMATを設定したいと思います。

[
    {
      "IP": "10.240.82.192",
      "STATUS": "PASS",
      "SOFTWARE": "1.0.0",
      "KERNEL": "5.0.0"
    },
    {
      "IP": "10.240.82.193",
      "STATUS": "PASS",
      "SOFTWARE": "1.0.0",
      "KERNEL": "5.0.3"
    },
    {
      "IP": "10.240.82.194",
      "STATUS": "PASS",
      "SOFTWARE": "1.0.2",
      "KERNEL": "5.0.1"
    }
]

このコマンドを試しました（サンプルデータをjson.dataに保存しました）。

cat json.data|jq -r '{IP:.[].ip,STATUS:.[].status,SOFTWARE:.[].info.software.version,KERNEL:.[].info.kernel}'

動作せず、次のように出力されます。

私が望むものを得るための正しいcliコマンドを知りたいです。

非常にありがとう

指定した4つの要素のそれぞれに対して、コマンドが各配列要素に対して繰り返されるため、3つではなく3 4 = 81個のオブジェクトが生成されます。

各オブジェクトを繰り返すには、map()次の関数を使用できます。

jq 'map({IP:.ip, STATUS:.status, SOFTWARE:.info.software.version, KERNEL:.info.kernel})' json.data

[
  {
    "IP": "10.240.82.192",
    "STATUS": "PASS",
    "SOFTWARE": "1.0.0",
    "KERNEL": "5.0.0"
  },
  {
    "IP": "10.240.82.193",
    "STATUS": "PASS",
    "SOFTWARE": "1.0.0",
    "KERNEL": "5.0.3"
  },
  {
    "IP": "10.240.82.194",
    "STATUS": "PASS",
    "SOFTWARE": "1.0.2",
    "KERNEL": "5.0.1"
  }
]
