Modify Prefab in batches in Unity editor

I recently wrote some small tools, record and share them

tool

  [MenuItem("Assets/工具/赋值")]
    public static void SetSelectedPrefabsValue()
    {
    
    
        Debug.Log($"数量{
      
      Selection.gameObjects.Length}");
        if (Selection.gameObjects.Length == 0)return;
        foreach (var obj in Selection.gameObjects)
        {
    
    
            GameObject go = obj;
          
            /*
            ScriptA a= go.GetComponent<ScriptA>();
            ScriptB b= go.GetComponentInChildren<ScriptB>();
            a.fireOutLine = effect;
            */
            PrefabUtility.SavePrefabAsset(go);

        }
    }

Nanny tutorial:
Write the operation you want to perform in the comment area. For example, here is to find b from the sub-object and assign it to the fireOutLine attribute of a.
It is used when there are a large number of prefabs with the same script that need to be mounted on nodes, or when a large number of prefabs of the same type need to perform the same operation.
Instructions for use: Select all Prefabs that need to be modified, right-click Tools/Assignment Execute

Inspector mounting attribute, and Find attribute in Start

Mounting properties improves code readability and maintainability, and is often faster than using Find.

How to display Private properties in Inspector
