以防万一，我的原始 json 如下所示：

{
  "taskDefinition": {
    "containerDefinitions": [
      {
        "name": "web",
        "image": "my-image",
        "environment": [
          {
            "name": "DB_HOST",
            "value": "localhost"
          },
          {
            "name": "DB_USERNAME",
            "value": "user"
          }
        ]
      }
    ]
  }
}

我想就地修改匹配键的值，如下所示：

jq '.taskDefinition.containerDefinitions[0].environment[] | select(.name=="DB_USERNAME") | .value="new"' json

我得到了输出

{
  "name": "DB_USERNAME",
  "value": "new"
}

但我想要更像就地修改或原始的整个 json 并修改新值，如下所示：

{
      "taskDefinition": {
        "containerDefinitions": [
          {
            "name": "web",
            "image": "my-image",
            "environment": [
              {
                "name": "DB_HOST",
                "value": "localhost"
              },
              {
                "name": "DB_USERNAME",
                "value": "new"
              }
            ]
          }
        ]
      }
    }

是否可以使用 …
