Lua中遍历文件操作代码实例

--[[检查所有.txt文件比如A.txt中第一行规定有20列，但是在X行中多输入一个Tab，则输出:A表的X行填写不规范，行末有多余填写]] getinfo = io.popen('dir ..//file /b /s')all = getinfo:read('*all') local filenameList = io.open("filename.txt", "wb")filenameList:write("Path/n")filenameList:close() filenameList = io.open("filename.txt", "a")filenameList:write(all)io.close(filenameList)io.close(getinfo)  local filenameList = tab.Open([[../filename.txt]], "Path", false) for index, Row in ipairs(filenameList) dolocal pathlist = Row["Path"]local rowString = string.find(pathlist, ".txt")if rowString ~= nil and rowString ~="" thenmoon.CheckRowlength(pathlist, pathlist)endend io.popen('dir /b /s')是windows下的，通过执行命令行dir获得io.popen('ls')是linux下的
