Batch file to add today's date, yesterday's date, previous day's date as extension to file name

问题

The following takes a file, MB5L.txt and compresses it into a zip file with the date as part of the file name:

@For /F "tokens=1,2,3,4 delims=/ " %%A in ('Date /t') do @(
    Set DayW=%%A
    Set Day=%%B
    Set Month=%%C
    Set Year=%%D
    Set All=%%D%%B%%C
)

"C:\Windows\CWBZIP.EXE" "c:\transfer\ziptest%All%.zip" "C:\transfer\MB5L.txt"

Today, it will take MB5L.txt and compress it to ziptest20120204.zip.

I want to take a file named MB5L201202.txt and compress it to MB5L20120202.zip where the "20120202" is a variable, thus allowing an administrator to run a batch file on Monday morning to archive files from the weekend.

Any suggestions greatly appreciated.

so you want today date or yesterday to include in the output name? If yesterday i have done one.. which can share with you!

 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

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%

: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%

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

if /I %mm% LSS 10 set mm=0%mm%
