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

不认真，直接复制你的代码，echo时没改出错了
