批处理bat删除指定天数日期之前的文件夹

【方案一】bat + reg + vbs

@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

【方案二】bat + reg + ritchie lawrence 日期函数

@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。

【方案三】bat + vbs

@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

@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
