【方案一】bat + date.exe(gnu)
代码如下:
@echo off
rem 调用gnu for win32的date.exe
set gnudate=c:/test/date.exe
rem 指定月数
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
代码如下:
@echo off
rem 指定月数
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
