使用 jq 从 JSON 获取单个值

Question

我试图了解正确使用 jq 来解析。json output
我有这个文件：

{

    "collections":[
        {
            "id":"XXXXX-XXXX-XXXXX-XXXXX-XXXXXXX",
            "name":"Collection One",
            "owner":"me",
            "uid":"10020232-XXXXX-XXXX-XXXXX-XXXXX-XXXXXXX",
            "isPublic":false
        },
        {
            "id":"YYYYY-YYYY-YYYYY-YYYYY-YYYYYYY",
            "name":"Collection Two",
            "owner":"me",
            "uid":"10020232-YYYYY-YYYY-YYYYY-YYYYY-YYYYYYY",
            "isPublic":false
        },
        {
            "id":"ZZZZZ-ZZZZ-ZZZZZ-ZZZZZ-ZZZZZZZ",
            "name":"Collection Three",
            "owner":"me",
            "uid":"ZZZZZ-ZZZZ-ZZZZZ-ZZZZZ-ZZZZZZZ",
            "isPublic":false
        },
}

我可以以某种方式获得带有“名称”的集合的“uid”：“Collecion Three”
任何类似 SELECT uid FROM collections WHERE "name" = "Collection Three"

谢谢大家

jq有一个select过滤器：

.collections[] | select(.name == "Collection Three").uid
