[日期时间] [已解决]BAT批处理如何把前一天的日期替换成当天的日期？

@echo off
for /f "delims=" %%i in ('dir /s/b *.txt') do (
for /f "delims=" %%a in ('type "%%~fi"') do (
set "foo=%%a"
call,set foo=%%foo:15012014=%date:~8,2%%date:~5,2%%date:~0,4%%%
call,echo/%%foo%%>>"%%~fi._" 
)
 move "%%~fi._" "%%~fi" 
)
pause
exit
复制代码

@echo off
  for /f "delims=" %%i in ('dir /s/b *.txt') do (
         for /f "delims=" %%a in ('type "%%~fi"') do (
                 set "foo=%%a"
                  call,set foo=%%foo:15012014=%date:~8,2%%date:~5,2%%date:~0,4%%%
                 call,echo/%%foo%%>>"%%~fi._"
)
  move "%%~fi._" "%%~fi"
)
pause
exit

大概就差一步了

for /f "delims=" %%i in ('dir /s/b *.txt') do (

原来是前一天日期换成当天 前面没看清 重写

@echo off
set adate=%date:~,4%%date:~5,2%%date:~8,2%
set /a y=%date:~,4%,d=1%date:~8,2%-100,"m=(1%date:~5,2%-91)%%12+4,y-=m/14"
set /a "JD=1461*Y/4+153*M/5+d-5071,y=(JD*4-489)/1461,d=jd-1461*y/4,m=d*100/3061,d-=153*m/5-100,y+=m/14,m-=m/14*12-99"
set "qdate=%y%%m:~-2%%d:~-2%"
setlocal enabledelayedexpansion
for /f "delims=" %%i in ('dir /s/b *.txt') do (
    (for /f "delims=" %%a in ('type "%%~fi"') do (
        set "foo=%%a"
        set foo=!foo:%qdate%=%adate%!
        echo;!foo! 
    ))>"%%~fi._"
    move "%%~fi._" "%%~fi"
)
pause

你没仔细看吧，类似这样改

@echo off
::需要调用VBS
rem 指定天数
set DaysAgo=1
>"%temp%\MyDate.vbs" echo LastDate=date()-%DaysAgo%
>>"%temp%\MyDate.vbs" echo FmtDate=right(year(LastDate),4) ^& right("0" ^& month(LastDate),2) ^& right("0" ^& day(LastDate),2)
>>"%temp%\MyDate.vbs" echo wscript.echo FmtDate
for /f %%a in ('cscript /nologo "%temp%\MyDate.vbs"') do (
  set DstDate=%%a
)
set DstDate=%DstDate:~6,2%%DstDate:~4,2%%DstDate:~0,4%

set curdate=%date:~8,2%%date:~5,2%%date:~0,4%
setlocal enabledelayedexpansion
for /f "delims=" %%i in ('dir /s/b *.txt') do (
    (for /f "delims=" %%a in ('type "%%~fi"') do (
        set "foo=%%a"
        set foo=!foo:%dstdate%=%curdate%!
        echo,!foo!
    ))>"%%~fi._"
    move "%%~fi._" "%%~fi" 
)
pause
exit
复制代码

不认真，直接复制你的代码，echo时没改出错了

%date:~8,2%%date:~5,2%%date:~0,4% 这个是当天的日期，你要把15012014替换成当天的日期？
