带我做甚

脚本支持通配符，功能:查找文件、目录位置。下面放源代码

function QZQZ()
local n=0
os.execute("touch /mnt/sdcard/xxxx/namm.txt")
if getText(DEFAULT_WINDOW_NAME,"UI_WJMC")=="" or getText(DEFAULT_WINDOW_NAME,"UI_WJFW")=="" then
setText(DEFAULT_WINDOW_NAME,"UI_WJLJ","重新输入")
goto A
end
local bb=" "..getText(DEFAULT_WINDOW_NAME,"UI_WJFW")
local aa=" "..getText(DEFAULT_WINDOW_NAME,"UI_WJMC")
aa="su -c find"..bb.." -name "..aa.." > /mnt/sdcard/xxxx/namm.txt"
aa=string.format(aa)
os.execute(aa)
local file=io.open("/mnt/sdcard/xxxx/namm.txt","r")
repeat
local sdata=file:read()
if sdata==nil and n==0 then setText(DEFAULT_WINDOW_NAME,"UI_WJLJ","没有找到") goto A end
if sdata~=nil then
sdata=string.sub(sdata,2,-1)
n=n+1
str=string.format("%s",n)
newLine()
createEditText("UI_WJLJ"..str,"文件路径",EDIT_TYPE_TEXT)
setText(DEFAULT_WINDOW_NAME,"UI_WJLJ"..str,sdata)
end
until sdata==nil or n>=1000
setText(DEFAULT_WINDOW_NAME,"UI_WJLJ","找到"..str.."个")
file:close()
--os.execute("rm /mnt/sdcard/xxxx/namm.txt")
::A::
end
-- 创建脚本界面入口
function createUI()
showLoopSetting(false)
mk,nk = getResolutionRatio();
createTextView("UI_TZ","可以输入通配符*?等.本工程在/mnt/sdcard/xxxx用了1个监时文件,namm.txt xxxx/下有这个文件的请改名要不会被删除的")
newLine()
createTextView("UI_TZ2","输入查找范围",math.floor(300*mk/720))
newLine()
createEditText("UI_WJFW","/mnt",EDIT_TYPE_LINE,math.floor(600*mk/720))
newLine()
createTextView("UI_TZ1","输入文件或目录名称",math.floor(300*mk/720))
newLine()
createEditText("UI_WJMC","",EDIT_TYPE_LINE,math.floor(600*mk/720))
newLine()
createEditText("UI_WJLJ","",EDIT_TYPE_TEXT)
setText(DEFAULT_WINDOW_NAME,"UI_WJLJ","输完后请按确认")
newLine()
createButton("UI_QZQZ","确认","QZQZ")
end
-- 脚本执行入口
function main()
end

行么，file报错
