尝试使用jq更新具有变量路径的值

{
  "person": {
    "name": "John",
    "age": 30
  }
}

echo '{"person": {"name": "John", "age": 30}}' | jq '.person.name = "Jane"'

{
  "person": {
    "name": "Jane",
    "age": 30
  }
}

path=".person.name"
value="Jane"
echo '{"person": {"name": "John", "age": 30}}' | jq --arg p "$path" --arg v "$value" '$p = $v'

{
  "person": {
    "name": "Jane",
    "age": 30
  }
}

{
  "people": [
    {
      "name": "John",
      "age": 30
    },
    {
      "name": "Jane",
      "age": 25
    }
  ]
}

echo '{"people": [{"name": "John", "age": 30}, {"name": "Jane", "age": 25}]}' | jq '.people[1].name = "Alice"'

{
  "people": [
    {
      "name": "John",
      "age": 30
    },
    {
      "name": "Alice",
      "age": 25
    }
  ]
}
