Get the output of a jq command and iterate over them in a bash script


I have the following json that I need to parse values in a bash script.

I went with jq to parse these results but I'm stuck on how to iterate values over the output of my jq command

jq -c --raw-output '.[] | {matrixId: .matrixId, state: .state, details: .axes[].details, device: .axes[].device, webLink: .webLink} | to_entries | map({key:.key, value:.value})'

I want to get the following result

[
  {
    "key": "matrixId",
    "value": "matrix-2h44ka21lln62"
  },
  {
    "key": "state",
    "value": "FINISHED"
  },
  {
    "key": "details",
    "value": "0 test cases failed"
  },
  {
    "key": "device",
    "value": "iphone8-15.7-en-portrait"
  },
  {
    "key": "webLink",
    "value": "https://console.firebase.google.com/project/app-54934/testlab/histories/bh.388190097b1eab25/matrices/4663013071689981858/details"
  }
],
[
  {

  },
  {

  },

  }

  }
]

It returns the output as three array objects with no comma separated value which is blocking me on iterating over them

I tried to search on how can I join them through piping but it's not working as expected


Solution

  • .[] iterates over the elements in an array and returns a stream of elements. So the input [1,2,3] will be returned as 1 2 3 when filtered through .[].

    Now you could stream the array's elements, apply a transformation, and then collect them again: [.[] | f], but hold on. There's a better way: map(f).

    Applying this idea to your program gives:

    jq -c 'map({matrixId, state, details: .axes[].details, device: .axes[].device, webLink} | to_entries[])'
    

    (Not sure why you have to_entries | map({key:.key, value:.value}), because to_entries already returns objects of that form.)

    Output:

    [
      {
        "key": "matrixId",
        "value": "matrix-2h44ka21lln62"
      },
      {
        "key": "state",
        "value": "FINISHED"
      },
      {
        "key": "details",
        "value": "0 test cases failed"
      },
      {
        "key": "device",
        "value": "iphone8-15.7-en-portrait"
      },
      {
        "key": "webLink",
        "value": "https://console.firebase.google.com/project/app-54934/testlab/histories/bh.388190097b1eab25/matrices/4663013071689981858/details"
      },
      {
        "key": "matrixId",
        "value": "matrix-8hj1qx8udleaa"
      },
      {
        "key": "state",
        "value": "FINISHED"
      },
      {
        "key": "details",
        "value": "0 test cases failed"
      },
      {
        "key": "device",
        "value": "iphone8-15.7-en-portrait"
      },
      {
        "key": "webLink",
        "value": "https://console.firebase.google.com/project/app-54934/testlab/histories/bh.388190097b1eab25/matrices/5654175129805154564/details"
      },
      {
        "key": "matrixId",
        "value": "matrix-2i6y9uq9i0ext"
      },
      {
        "key": "state",
        "value": "FINISHED"
      },
      {
        "key": "details",
        "value": "0 test cases failed"
      },
      {
        "key": "device",
        "value": "iphone8-15.7-en-portrait"
      },
      {
        "key": "webLink",
        "value": "https://console.firebase.google.com/project/app-54934/testlab/histories/bh.388190097b1eab25/matrices/4958041021718608851/details"
      }
    ]
    

    If you want an array of arrays, then don't iterate to_entries and simply map to the entries array:

    jq 'map({matrixId, state, details: .axes[].details, device: .axes[].device, webLink} | to_entries)'
    

    Output:

    [
      [
        {
          "key": "matrixId",
          "value": "matrix-2h44ka21lln62"
