让JSON输出grep-able？

Question

我的JSON输出看起来像这样;

{  
   "1":{  
      "state":{  
         "on":false,
         "bri":124,
         "hue":14985,
         "sat":252,
         "effect":"none",
         "xy":[  
            0.5182,
            0.4363
         ],
         "ct":480,
         "alert":"none",
         "colormode":"xy",
         "reachable":true
      },
      "type":"Extended color light",
      "name":"Slaapkamer rechts",
      "modelid":"LCT001",
      "manufacturername":"Philips",
      "uniqueid":"00:17:88:01:00:dc:36:68-0b",
      "swversion":"66013187"
   },
   "2":{  
      "state":{  
         "on":false,
         "bri":125,
         "hue":14984,
         "sat":252,
         "effect":"none",
         "xy":[  
            0.5182,
            0.4363
         ],
         "ct":480,
         "alert":"none",
         "colormode":"xy",
         "reachable":true
      },
      "type":"Extended color light",
      "name":"Slaapkamer links",
      "modelid":"LCT001",
      "manufacturername":"Philips",
      "uniqueid":"00:17:88:01:00:dc:33:99-0b",
      "swversion":"66013187"
   }
}

有谁知道一个简单的方法来使这个输出grep-able？或者将输出放在一行上的任何其他方法,以便我可以在json输出上使用像grep,awk等工具？如果我现在在'hue'这个词上做一个grep然后我得到2行;

"hue":14985,
"hue":14984,

虽然我有时只想在第一个或第二个上涂鸦.

有任何想法吗？

用jq:

jq '.["1"].state.hue' file

输出:

14985

不可能使用,'.1.state.hue'因为数字是一种特殊情况.

jq '.["2"].state.hue' file

输出:

14984

jq '.[].state.hue' file

输出:

14984
14985
