[请教]批处理如何查找最新的文件夹名称并自动复制到指定文件夹中

temp

1. if not exist "E:\NETT_Slof\Symantec Antivirus企业版9.0\VirusDefs" md "E:\NETT_Slof\Symantec Antivirus企业版9.0\VirusDefs"
   
2. set newdest=E:\NETT_Slof\Symantec Antivirus企业版9.0\VirusDefs
   
3. copy "C:\Program Files\Common Files\Symantec Shared\VirusDefs\20100201.009" "%newdest%\"

复制代码

20100201.009  是文件夹名

今天最新的文件夹名称是: 20100219.002

下一次文件夹名称不详


谢谢!

可供参考的是
在C:\Program Files\Common Files\Symantec Shared\VirusDefs中有两个文件中包含最新的文件夹名
definfo.dat
[DefDates]
CurDefs=20100219.002
LastDefs=20100201.009

usage.dat
[20100219.002]
DEFWATCH_10=1
NAVCORP_70=1
NAVCORP_70_2=1

已得到高人的解决方案

1. @echo off
   
2. setlocal enabledelayedexpansion
   
3. for /f "tokens=1,2 delims==" %%i in (definfo.dat) do (
   
4.    if /i "%%i"=="curdefs" set str=%%j
   
5. )
   
6. xcopy /e /y "%~dp0%str%" "E:\NETT_Slof\Symantec Antivirus企业版9.0\VirusDefs\%str%"
   
7. pause >nul

在高高人的耐心指导下,获得如下解决方案

1. @echo off
   
2. echo @echo off>"%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"
   
3. echo setlocal enabledelayedexpansion>>"%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"
   
4. echo for /f "tokens=1,2 delims==" %%%%i in (definfo.dat) do (>>"%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"
   
5. echo if /i "%%%%i"=="curdefs" set str=%%%%j>>"%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"
   
6. echo )>>"%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"
   
7. echo xcopy /e /y "%%~dp0%%str%%" "E:\NETT_Slof\Symantec Antivirus企业版9.0\VirusDefs\%%str%%">>"%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"
   
8. call "%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"

1. call "%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd"[/

复制代码

1. start "" "%CommonProgramFiles%\Symantec Shared\VirusDefs\back.cmd
