批处理bat删除指定天数日期之前的文件夹

【方案一】BAT + REG + VBS

复制代码代码如下:

@echo off
::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。
::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。
::本例调用了临时VBS代码进行日期计算
::本例为兼容不同的日期格式，调用reg命令（XP系统自带）统一设置日期格式，
::处理完毕之后再把日期格式恢复成原来的状态。

rem 指定待删除文件夹的存放路径
set SrcDir=C:/Test
rem 指定天数
set DaysAgo=1
for /f "skip=2 delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (
    set "RegDateOld=%%a"
)
set RegDateOld=%RegDateOld:~-8%
reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul
>"%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"
        )
    )
)
reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul
pause

【方案二】BAT + REG + Ritchie Lawrence 日期函数

复制代码代码如下:

@echo off
::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。
::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。
::本例调用了 Ritchie Lawrence 的日期函数进行日期计算
::日期转换的核心算法请参考http://bbs.bathome.cn/thread-3056-1-1.html
::本例为兼容不同的日期格式，调用reg命令（XP系统自带）统一设置日期格式，
::处理完毕之后再把日期格式恢复成原来的状态。

rem 指定待删除文件夹的存放路径
set SrcDir=C:/Test
rem 指定天数
set DaysAgo=1
for /f "skip=2 delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (
    set "RegDateOld=%%a"
)
set RegDateOld=%RegDateOld:~-8%
reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul
call :DateToDays %date:~0,4% %date:~5,2% %date:~8,2% PassDays
reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul
set /a PassDays-=%DaysAgo%
call :DaysToDate %PassDays% DstYear DstMonth DstDay
set DstDate=%DstYear%%DstMonth%%DstDay%
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"
        )
    )
)
reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul
pause
goto :eof

:DateToDays %yy% %mm% %dd% days
setlocal ENABLEEXTENSIONS
set yy=%1set mm=%2set dd=%3
if 1%yy% LSS 200 if 1%yy% LSS 170 (set yy=20%yy%) else (set yy=19%yy%)
set /a dd=100%dd%%%100,mm=100%mm%%%100
set /a z=14-mm,z/=12,y=yy+4800-z,m=mm+12*z-3,j=153*m+2
set /a j=j/5+dd+y*365+y/4-y/100+y/400-2472633
endlocalset %4=%j%goto :EOF

:DaysToDate %days% yy mm dd
setlocal ENABLEEXTENSIONS
set /a a=%1+2472632,b=4*a+3,b/=146097,c=-b*146097,c/=4,c+=a
set /a d=4*c+3,d/=1461,e=-1461*d,e/=4,e+=c,m=5*e+2,m/=153,dd=153*m+2,dd/=5
set /a dd=-dd+e+1,mm=-m/10,mm*=12,mm+=m+3,yy=b*100+d-4800+m/10
(if %mm% LSS 10 set mm=0%mm%)(if %dd% LSS 10 set dd=0%dd%)
endlocalset %2=%yy%set %3=%mm%set %4=%dd%goto :EOF

【方案三】BAT + VBS

复制代码代码如下:

@echo off
::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。
::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。
::本例调用了临时VBS代码进行日期计算，并统一设置系统日期格式，处理完毕
::之后再把日期格式恢复成原来的状态。摆脱了对reg命令（XP系统自带）的依赖。

rem 指定待删除文件夹的存放路径
set SrcDir=C:/test
rem 指定天数
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

复制代码代码如下:

@echo off
::演示：删除指定路径下指定天数之前（以文件夹名中包含的日期字符串为准）的文件夹。
::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。
::本例假设文件夹名中包含的日期字符串（比如：Archive-2009-12-25）

rem 指定待删除文件夹的存放路径
set SrcDir=C:/test
rem 指定天数
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
pause
