Question

我只想找到一种使用shellcript搜索jq的方法，让我们更好地解释一下：

我有这个json文件：

   {
      "meta": {
        "limit": 200,
        "next": null,
        "offset": 0,
        "previous": null,
        "total_count": 2
      },
      "objects": [
        {

          "service_type": "conference",
          "signalling_node": "192.168.20.11",
          "source_alias": "h323:192.168.51.153",
          "system_location": "CUSTOMER-JG-LAN",
          "vendor": "TANDBERG (Tandberg 529)"
        },
        {
          "bandwidth": 1280,
          "call_direction": "in",

          "is_presenting": false,
          "is_streaming": false,
          "license_count": 1,
          "license_type": "port",
          "media_node": "172.24.25.106",
          "parent_id": "",
          "participant_alias": "John",
          "protocol": "WebRTC",
          "remote_address": "179.65.15.9",

          "service_type": "conference",
          "signalling_node": "172.24.25.106",
          "source_alias": "John",
          "vendor": "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36"
        }
      ]
    }

我希望在“会议”Json TAG中找到一个元素，当我找到会议名称时，我想知道在找到会议价值后如何带来“connect_time”：

这是一个例子，我的意思是：会议“：”JOG1_VMR6“

我想找到解决这个问题的“connect_time”是什么，所以我在下面构建了这部分代码：

time=$(cat service.html 2>/dev/null | jq  '.objects[] | select(.conference=='JOG1_VMR6')' | jq  ".connect_time" |  grep -o "[^\"]*" | grep -o "[^T][0-9].*" | grep -o "[0-9]\{2\}:[0-9]\{2\}:[0-9].")

但是select（.conference =='JOG1_VMR6'）'在shell中显示编译错误，不会给我带来“connect_time”：“2017-01-26T19：20：01.096940”所以我不能解析它是正确的。

Answer 1

这里成功的关键是简单。只需调用一次jq：

jq  '.objects[] | select(.conference=="JOG1_VMR6") | .connect_time'

所有这些grep调用也可以大大简化或完全取消 - 例如考虑：

jq -n -r '"2017-01-26T19:20:01.096940" | sub(".*T(?<t>..:..:..).*"; .t)'
19:20:01

或只是：

jq -n -r '"2017-01-26T19:20:01.096940" | .[11:19]'
19:20:01

Shell脚本更复杂的jq选择
