JSON filter a JSON with wildcards and keynames-CodePudding

How to parse a JSON to when a few values are string and other are list.

I have a list like this:

{
  "abc": {
    "enabled": true
  },
  "def": {
    "enabled": false
  },
  "ghi": [
    {
      "enabled": false,
      "name": "HELLO",
      "useless": "DO NOT WANT THIS"
    }
  ],
  "jkl": [
    {
      "enabled": true,
      "name": "HI"
    }
  ],
  "mko": {
    "enabled": false,
    "something unwanted": 123
  },
  "pqr": {
    "enabled": true
  }
}

Trying to filter only by the two key(enabled and name like abc):

{
  "abc": {
    "enabled": true
  },
  "def": {
    "enabled": false
  },
  "ghi": [
    {
      "enabled": false,
      "name": "HELLO"
    }
  ],
  "jkl": [
    {
      "enabled": true,
      "name": "HI"
    }
  ],
  "mko": {
    "enabled": false
  },
  "pqr": {
    "enabled": true
  }
}

Tried several answers on SO, but nothing is giving the desired result. I am not a regular consumer of JSON so this question might sounds stupid.

jq -r '[*].enabled' file
jq: error: syntax error, unexpected '*' (Unix shell quoting issues?) at <top-level>, line 1:
[*].enabled
jq: 1 compile error

CodePudding user response：

You can use a combination of objects and arrays to select the items to update with |=, then with_entries to access the .key which can be queried with IN:

< file jq '
  (.[] | objects, (arrays[] | objects))
    |= with_entries(select(.key | IN("enabled", "name")))
'

{
  "abc": {
    "enabled": true
  },
  "def": {
    "enabled": false
  },
  "ghi": [
    {
      "enabled": false,
      "name": "HELLO"
    }
  ],
  "jkl": [
    {
      "enabled": true,
      "name": "HI"
    }
  ],
  "mko": {
    "enabled": false
  },
  "pqr": {
    "enabled": true
  }
}
