【方案一】bat + reg + vbs

代碼如下:

@echo off

::演示：刪除指定路徑下指定天數(shù)之前（以文件夾的最后修改日期為準）的文件夾。

::如果演示結(jié)果無誤，把rd前面的echo去掉，即可實現(xiàn)真正刪除。

::本例調(diào)用了臨時vbs代碼進行日期計算

::本例為兼容不同的日期格式，調(diào)用reg命令（xp系統(tǒng)自帶）統(tǒng)一設(shè)置日期格式，

::處理完畢之后再把日期格式恢復(fù)成原來的狀態(tài)。

【方案二】bat + reg + ritchie lawrence 日期函數(shù)

代碼如下:

@echo off

::演示：刪除指定路徑下指定天數(shù)之前（以文件夾的最后修改日期為準）的文件夾。

::如果演示結(jié)果無誤，把rd前面的echo去掉，即可實現(xiàn)真正刪除。

::本例調(diào)用了 ritchie lawrence 的日期函數(shù)進行日期計算

::日期轉(zhuǎn)換的核心算法請參考http://bbs.bathome.cn/thread-3056-1-1.html

::本例為兼容不同的日期格式，調(diào)用reg命令（xp系統(tǒng)自帶）統(tǒng)一設(shè)置日期格式，

::處理完畢之后再把日期格式恢復(fù)成原來的狀態(tài)。

【方案三】bat + vbs

代碼如下:

@echo off

::演示：刪除指定路徑下指定天數(shù)之前（以文件夾的最后修改日期為準）的文件夾。

::如果演示結(jié)果無誤，把rd前面的echo去掉，即可實現(xiàn)真正刪除。

::本例調(diào)用了臨時vbs代碼進行日期計算，并統(tǒng)一設(shè)置系統(tǒng)日期格式，處理完畢

::之后再把日期格式恢復(fù)成原來的狀態(tài)。擺脫了對reg命令（xp系統(tǒng)自帶）的依賴。

rem 指定待刪除文件夾的存放路徑

set srcdir=c:/test

rem 指定天數(shù)

set daysago=1

>%temp%/backupdate.vbs echo set wshshell = wscript.createobject(wscript.shell)

>>%temp%/backupdate.vbs echo wscript.echo wshshell.regread (hkey_current_user/control panel/international/sshortdate)

for /f %%a in ('cscript /nologo %temp%/backupdate.vbs') do (

set regdateold=%%a

)

>%temp%/unifydate.vbs echo set wshshell = wscript.createobject(wscript.shell)

>>%temp%/unifydate.vbs echo wshshell.regwrite hkey_current_user/control panel/international/sshortdate, yyyy-m-d, reg_sz

cscript /nologo %temp%/unifydate.vbs

>%temp%/dstdate.vbs echo lastdate=date()-%daysago%

>>%temp%/dstdate.vbs echo fmtdate=right(year(lastdate),4) ^& right(0 ^& month(lastdate),2) ^& right(0 ^& day(lastdate),2)

>>%temp%/dstdate.vbs echo wscript.echo fmtdate

for /f %%a in ('cscript /nologo %temp%/dstdate.vbs') do (

set dstdate=%%a

)

set dstdate=%dstdate:~0,4%-%dstdate:~4,2%-%dstdate:~6,2%

for /d %%a in (%srcdir%/*.*) do (

if %%~ta leq %dstdate% (

if exist %%a/

echo rd /s /q %%a

)

)

)

>%temp%/recoverdate.vbs echo set wshshell = wscript.createobject(wscript.shell)

>>%temp%/recoverdate.vbs echo wshshell.regwrite hkey_current_user/control panel/international/sshortdate, %regdateold%, reg_sz

cscript /nologo %temp%/recoverdate.vbs

pause

【方案四】字符串截取

代碼如下:

@echo off

::演示：刪除指定路徑下指定天數(shù)之前（以文件夾名中包含的日期字符串為準）的文件夾。

::如果演示結(jié)果無誤，把rd前面的echo去掉，即可實現(xiàn)真正刪除。

::本例假設(shè)文件夾名中包含的日期字符串（比如：archive-2009-12-25）

rem 指定待刪除文件夾的存放路徑

set srcdir=c:/test

rem 指定天數(shù)

set daysago=1

>%temp%/dstdate.vbs echo lastdate=date()-%daysago%

>>%temp%/dstdate.vbs echo fmtdate=right(year(lastdate),4) ^& right(0 ^& month(lastdate),2) ^& right(0 ^& day(lastdate),2)

>>%temp%/dstdate.vbs echo wscript.echo fmtdate

for /f %%a in ('cscript /nologo %temp%/dstdate.vbs') do (

set dstdate=%%a

)

set dstdate=%dstdate:~0,4%-%dstdate:~4,2%-%dstdate:~6,2%

setlocal enabledelayedexpansion

for /d %%a in (%srcdir%/*.*) do (

if %%~ta leq %dstdate% (

set folderdate=%%~na

set folderdate=!folderdate:~8,10!

if !folderdate! leq %dstdate% (

if exist %%a/ (

echo rd /s /q %%a

)

)

)

)

endlocal
