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
