合并特定文件夹中的所有JSON文件

I have a folder with a number of JSON files within it.

我有一个包含许多JSON文件的文件夹。

I want to take all .json files, where the filename ends with _LAST.json, and combine them into one JSON file. Each of the files that are to be processed are named like:

我想获取所有.json文件，其中文件名以_LAST.json结尾，并将它们合并为一个JSON文件。要处理的每个文件都命名为：

Bill_LAST.json
Jane_LAST.json
Kitty_LAST.json

Bill_LAST.json looks like:

Bill_LAST.json看起来像：

[{

    "Date": "2012-11-19",
    "Name": "Bill",
    "Age": 54,
    "Sex": "M"

}]
