【方案一】BAT + date.exe(GNU)
復(fù)制代碼 代碼如下:
@echo off
rem 調(diào)用GNU for Win32的date.exe
set "gnuDate=C:/test/date.exe"
rem 指定月數(shù)
set MonthsAgo=1
for /f %%a in ('%gnuDate% -d "%MonthsAgo% months ago" "+%%Y-%%m-01"') do (
set "DstDate=%%a"
)
)
echo,%DstDate%
pause
【方案二】BAT + VBS
復(fù)制代碼 代碼如下:
@echo off
rem 指定月數(shù)
set MonthsAgo=2
>"%temp%/DateCalculate.vbs" echo strLastDate=DateAdd("m", -%MonthsAgo%, Date)
>>"%temp%/DateCalculate.vbs" echo strFmtDate=Right(Year(strLastDate),4) ^ Right("0" ^ Month(strLastDate),2) ^ "01"
>>"%temp%/DateCalculate.vbs" echo WScript.Echo strFmtDate
for /f %%a in ('cscript /nologo "%temp%/DateCalculate.vbs"') do (
set "DstDate=%%a"
)
set DstDate=%DstDate:~0,4%-%DstDate:~4,2%-%DstDate:~6,2%
echo,%DstDate%
pause
