{
"name": "ford",
"availableVersions": [
{
"version": 111,
"count": 3
},
{
"version": 122,
"count": 2
},
{
"version": 133,
"count": 3
},
{
"version": 144,
"count": 1
}
],

}
{

},
{
"version": 255,
"count": 3
} ],
"RealVersion": 120
}
I have this demo.json file now if (name == 'ford')(name can be a variable) I want to get the all the versions whose count != 3
and if all the version's count == 3 I want to get the RealVersion of ford so in this case output should be.
EXPECTED OUTPUT = [122 144 ]
I am using jq tool for parsing the json file
Now if all the version count ==3
{
"name": "ford",
"availableVersions": [
{
"version": 111,
"count": 3
},
{
"version": 122,
"count": 3
},
{
"version": 133,
"count": 3
},
{
"version": 144,
"count": 3
}
],
"RealVersion": 155
}
{
"name": "bmw",
"availableVersions": [
{
"version": 244,
"count": 1
},
{
"version": 255,
"count": 3
} ],
"RealVersion": 120
}
Now in this case all the version's count == 3 so now I want to get the real version which is 155
EXPECTED OUTPUT SHOULD BE 155
CAN ANYONE HELP ME WITH THIS?

Answer 1

The following program, when invoked with the -n command-line option, produces the expected output in both cases:
inputs
| .RealVersion as $RealVersion
| select(.name == "ford")
| .availableVersions
| map(select(.count != 3))
| if length > 0 then map(.version)
else $RealVersion
end
Specifically, in the first case, it produces a JSON array, and in the second case, the actual value of .ReadVersion.
