Jak uzyskać wczorajszą datę w pliku wsadowym?

Question

używam poniżej kod, aby uzyskać dzisiejszą datę i miesiąc (0411)

For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set FileNameDatePrefix=%%a%%b) 

Ale chcę, aby uzyskać datę wczorajszą w FileNameDatePrefix.

Nie jestem pewien, jak możemy to zrobić. Wszelkie sugestie są mile widziane.

Answer 1

Oto jeden sposób:

@echo off 
setlocal 

Call :GetDateTime Year Month Day 
Echo %Year% %Month% %Day% 
Call :AddSubtractDate %Year% %Month% %Day% -1 Ret 
echo %Ret% 
exit /b 


:AddSubtractDate Year Month Day <+/-Days> Ret 
::Adapted from DosTips Functions:: 
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=%YYYY: =%%MM: =%%DD: =% 
endlocal & set %~5=%ret% 
exit /b 

:GetDateTime Year Month Day Hour Minute Second 
@echo off & setlocal 
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a" 
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"

    IF "%~6" NEQ "" set "%~6=%Sec%" 
) 
exit /b

Oto metoda plik wsadowy przy użyciu VBS, który jest mocny w każdej lokalizacji

:: 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 "data=%yyyy%-%mm%-%dd%" 

echo Yesterday was "%data%" 
pause

można spróbować to:

@echo off 

set yyyy= 

set $tok=1-3 
for /f "tokens=1 delims=.:/-, " %%u in ('date /t') do set $d1=%%u 
if "%$d1:~0,1%" GTR "9" set $tok=2-4 
for /f "tokens=%$tok% delims=.:/-, " %%u in ('date /t') do (
for /f "skip=1 tokens=2-4 delims=/-,()." %%x in ('echo.^|date') do (
set %%x=%%u 
set %%y=%%v 
set %%z=%%w 
set $d1= 
set $tok=)) 

if "%yyyy%"=="" set yyyy=%yy% 
if /I %yyyy% LSS 100 set /A yyyy=2000 + 1%yyyy% - 100 

set CurDate=%mm%/%dd%/%yyyy% 
set dayCnt=%1 

if "%dayCnt%"=="" set dayCnt=1 

REM Substract your days here 
set /A dd=1%dd% - 100 - %dayCnt% 
set /A mm=1%mm% - 100 

:CHKDAY 
if /I %dd% GTR 0 goto DONE 
set /A mm=%mm% - 1 
if /I %mm% GTR 0 goto ADJUSTDAY 
set /A mm=12 
set /A yyyy=%yyyy% - 1 

:ADJUSTDAY 
if %mm%==1 goto SET31 
if %mm%==2 goto LEAPCHK 
if %mm%==3 goto SET31 
if %mm%==4 goto SET30 
if %mm%==5 goto SET31 
if %mm%==6 goto SET30 
if %mm%==7 goto SET31 
if %mm%==8 goto SET31 
if %mm%==9 goto SET30 
if %mm%==10 goto SET31 
if %mm%==11 goto SET30 
REM ** Month 12 falls through 

:SET31 
set /A dd=31 + %dd% 
goto CHKDAY 

:SET30 
set /A dd=30 + %dd% 
goto CHKDAY 

:LEAPCHK 
set /A tt=%yyyy% %% 4 
if not %tt%==0 goto SET28 
set /A tt=%yyyy% %% 100 
if not %tt%==0 goto SET29 
set /A tt=%yyyy% %% 400 
if %tt%==0 goto SET29 

:SET28 
set /A dd=28 + %dd% 
goto CHKDAY 

:SET29 
set /A dd=29 + %dd% 
goto CHKDAY 

:DONE 
if /I %mm% LSS 10 set mm=0%mm% 
if /I %dd% LSS 10 set dd=0%dd% 

REM Set IIS and AWS date variables 
set IISDT=%yyyy:~2,2%%mm%%dd% 
set AWSDT=%yyyy%-%mm%-%dd% 
echo %IISDT% 
echo %AWSDT% 
pause

Answer 4

Ten kod działa tylko w systemie Vista i nowszych wersjach, ponieważ robocopy służy do pobierania aktualnej daty. Ale uniknie problemu z formatami lokalnymi w zmiennej %date%, wymaganej przez administratora dla wmic i tymczasowego pliku VBScript. W każdym razie podprogram, który otrzymuje dzisiejszą datę, można zastąpić innym kodem. :getYesterdayDate zajmie się wszystkimi kalikami, aby odjąć jeden dzień od dzisiaj.

@echo off 
setlocal enableextensions enabledelayedexpansion 

    call :getYesterdayDate yesterday 
    echo %yesterday% 

    exit /b 

:getYesterdayDate returnVar 
    setlocal enableextensions disabledelayedexpansion 
    call :getTodayDate today 
    for /f "tokens=1-3 delims=/ " %%a in ("%today%") do set /a "y=%%a", "m=1%%b-100", "d=1%%c-100" 
    if %d% gtr 1 (set /a "d-=1") else (
     if %m% equ 1 (set /a "y-=1" , "m=12") else (set /a "m-=1") 
     set /a "d=30+((m+m/8) %% 2)" 
     if %m%==3 set /a "d=d-2+!(y%%4)-!(y%%100)+!(y%%400)" 
    ) 
    set "d=0%d%" & set "m=0%m%" 
    endlocal & set "%~1=%y%/%m:~-2%/%d:~-2%" & exit /b 

:getTodayDate returnVar 
    setlocal enableextensions disabledelayedexpansion 
    set "today=" & for /f %%a in ('robocopy "|" . /njh') do if not defined today set "today=%%a" 
    endlocal & set "%~1=%today%" & exit /b
