我试图通过id从以下json中删除重复项
这是json：
{
"Result": [
{
"name": "validation-of-art",
"id": "12",
"status": "passed",
"duration": 4740302
},
{
"name": "validation-of-art",
"id": "12",
"status": "passed",
"duration": 272320
},
{
"name": "validation-of-art",
"id": "13",
"status": "passed",
"duration": 272320
}
]
}
以下是我尝试过的内容：
jq -r 'unique_by(.Result.name)'
以及jq 'unique_by(.Result[].name)'
我收到错误 - Cannot index array with string "Result"
任何帮助将不胜感激。

.Result个unique_by(.name)个对象之外的所有对象
$ jq -M '.Result |= unique_by(.name)' data.json
{
"Result": [
{
"name": "validation-of-art",
"id": "12",
"status": "passed",
"duration": 4740302
}
]
}
如果这不是您想要的，您可以轻松地概括这一点。例如。为每个可以使用的唯一{name,id}保留一个对象
$ jq -M '.Result |= unique_by({name, id})' data.json
{
"Result": [
{
"name": "validation-of-art",
"id": "12",
"status": "passed",
"duration": 4740302
},
{
"name": "validation-of-art",
"id": "13",
"status": "passed",
"duration": 272320
}
]
}
