设置昨天批处理文件

Question

如果这给了我今天的日期......

SET TODAY=%date:~7,2%.%date:~-10,2%.%date:~-4,4% 

...我怎样才能获得昨天的日期？我能以相同的风格获得它吗？

感谢您的帮助！

Answer 1

更改三个变量在第三顺序最后一行适合你：

:: yesterdays date 
@echo off 
set day=-1 
echo >"%temp%\%~n0.vbs" s=DateAdd("d",%day%,now) : d=weekday(s) 
echo>>"%temp%\%~n0.vbs" WScript.Echo year(s)^& right(100+month(s),2)^& right(100+day(s),2) 
for /f %%a in ('cscript /nologo "%temp%\%~n0.vbs"') do set "result=%%a" 
del "%temp%\%~n0.vbs" 
set "YYYY=%result:~0,4%" 
set "MM=%result:~4,2%" 
set "DD=%result:~6,2%" 
set "date-yesterday=%yyyy%-%mm%-%dd%" 

echo Yesterday was "%date-yesterday%" 
pause 

Answer 2

参照link。你将不得不调整剧本，以获得所需的格式（DD.MM.YYYY）

Answer 3

这里是一个脚本，我写这样做：

@echo off 
setlocal 

Call :GetDateTime Year Month Day 
Call :SubtractDate %Year% %Month% %Day% -1 Ret 
echo %Ret% 
pause 


:SubtractDate Year Month Day <+/-Days> Ret

setlocal & set a=%4 
set "yy=%~1"&set "mm=%~2"&set "dd=%~3" 
set /a "yy=10000%yy% %%10000,mm=100%mm% %% 100,dd=100%dd% %% 100" 
if %yy% LSS 100 set /a yy+=2000 &rem Adds 2000 to two digit years 
set /a JD=dd-32075+1461*(yy+4800+(mm-14)/12)/4+367*(mm-2-(mm-14)/12*12)/12-3*((yy+4900+(mm-14)/12)/100)/4 
if %a:~0,1% equ + (set /a JD=%JD%+%a:~1%) else set /a JD=%JD%-%a:~1% 
set /a L= %JD%+68569,  N= 4*L/146097, L= L-(146097*N+3)/4, I= 4000*(L+1)/1461001 
set /a L= L-1461*I/4+31, J= 80*L/2447, K= L-2447*J/80,  L= J/11 
set /a J= J+2-12*L,  I= 100*(N-49)+I+L 
set /a YYYY= I, MM=100+J, DD=100+K 
set MM=%MM:~-2% & set DD=%DD:~-2% 
set ret=%DD: =%.%MM: =%.%YYYY: =% 
endlocal & set %~5=%ret% 
exit /b
