使用LUA脚本搜索n个子文件夹中的文件

local lfs = require("lfs")

-- 定义搜索函数
local function searchFiles(folder, pattern, result)
    for file in lfs.dir(folder) do
        if file ~= "." and file ~= ".." then
            local filePath = folder .. "/" .. file
            local attr = lfs.attributes(filePath)
            if attr.mode == "directory" then
                -- 递归搜索子文件夹
                searchFiles(filePath, pattern, result)
            elseif attr.mode == "file" then
                -- 判断文件名是否符合搜索条件
                if string.match(file, pattern) then
                    table.insert(result, filePath)
                end
            end
        end
    end
end

-- 搜索n个子文件夹中的文件
local function searchInSubfolders(parentFolder, pattern, numSubfolders)
    local result = {}
    for i = 1, numSubfolders do
        local folder = parentFolder .. "/subfolder" .. i
        searchFiles(folder, pattern, result)
    end
    return result
end

-- 调用搜索函数并打印结果
local parentFolder = "/path/to/parent/folder"
local pattern = "%.txt$"  -- 搜索以".txt"结尾的文件
local numSubfolders = 5
local files = searchInSubfolders(parentFolder, pattern, numSubfolders)
for i, file in ipairs(files) do
    print(file)
end
