"domain": "test4.test.com",
"name": "test4"
}
],
"success": true,
"errors": [],
"messages": []
}

выполняю jq --arg param domain '.result[].domain' config.json - получаю все домены ( как и ожидаемо )
выполняю jq --arg param domain '.result[].$param' config.json - получаю синтаксическую ошибку
jq: error: syntax error, unexpected '$', expecting FORMAT or QQSTRING_START (Unix shell quoting issues?) at <top-level>, line 1:
.result[].$param
что делаю не так ?
