I want to get the value of my field from the my environments

environments
System-Provided:
{
 "VCAP_SERVICES": {
     "mySerivce" : {
       "url" :"myValue"
      },
      "mySerivce2" : {
       "url" :"myValue2"
      }
  }
}

I want to get the value of url from System-Provided -> "VCAP_SERVICES"-> "mySerivce2" ->

I tried

cf env myApp| grep url| cut -d ':' -f2)"

bu then I got two results from all the services How I can get result only from one service ? also there are many fields in each service

`url=$(jq -r '.VCAP_SERVICES.myService.url' – Charles Duffy Feb 07 '19 at 10:27
do I need to install jq ? – user1365697 Feb 07 '19 at 11:19
can I do it without jq ? – user1365697 Feb 07 '19 at 11:37
You could use Python instead (it's not hard to just have one shell function that starts a Python interpreter inside a larger shell script). You still need *something* with a real JSON parser. The linked-duplicate question has answers covering several other options. – Charles Duffy Feb 07 '19 at 16:12
`url=$(python -c "import sys, json; print(json.load(sys.stdin)['VCAP_SERVICES']['myService']['url'])" – Charles Duffy Feb 07 '19 at 16:21
