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) do
local pathlist = Row["Path"]
local rowString = string.find(pathlist, ".txt")
if rowString ~= nil and rowString ~="" then
moon.CheckRowlength(pathlist, pathlist)
end
end
 
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
