Batch file stumper

I am trying to write a command in a batch file that looks in a folder for the highest sequencial number, and renames it as the date.

IE, my backup program saves a file called BACKUP_000436.xml in a folder, and tomorrows will be BACKUP_000437.xml

Is there a command, that will look for the highest number, and when found, changes its name to the current date? such as BACKUP_032707, or even just the date.

Thanks

Try this from the directory where the files exist:

@echo off

setlocal

call :GETDATEPARTS "%date%"

set filePrefix=BACKUP_
set fileExt=.xml

set newFile=%filePrefix%%mm%%dd%%yy:~2%%fileExt%

if exist "%newFile%" echo File %newFile% has already been created for today.&goto :EOF

set fileMask=%filePrefix%*%fileExt%

for /f "tokens=*" %%a in ('dir /o-n /b /a-d "%fileMask%" 2^>NUL') do (
  echo Renaming %%a %newFile%
  ren "%%a" "%newFile%"
  goto :EOF
)

echo Could not locate any files matching %fileMask%

goto :EOF

:GETDATEPARTS

set dt=%~1
set tok=1-3

if "%dt:~0,1%" GTR "9" set tok=2-4

set yyyy=

for /f "tokens=%tok% delims=.:/-, " %%a in ('echo %~1') do (
  for /f "skip=1 tokens=2-4 delims=/-,()." %%x in ('echo.^|date') do set %%x=%%a&set %%y=%%b&set %%z=%%c
)

if not "%yyyy%"=="" set yy=%yyyy%

if 1%yy% LSS 1000 (if %yy% LSS 70 (set yy=20%yy%) else (set yy=19%yy%))
if 1%mm% LSS 100 set mm=0%mm%
if 1%dd% LSS 100 set dd=0%dd%

goto :EOF

Good Luck,
Steve

I tested it out on my XP/Pro machine and it worked fine.

What version of Windows do you have?

Did it issue any messages?

Please remove all debugging information you have placed in the batch processing.

I see you have changed certain aspects of the file, specifically filePrefix.

Please post the batch file as you are running it without the debugging information.

Also, please post any output without, if any.

We'll start from there.

I found a work around, Thanks for all the help

echo %date%
if %date:~0,1% GTR 9 echo %date% appears to have the 'day' && goto :Daydate
echo %date% doesn't have the dayname...
SET FDATE=%DATE:~0,2%-%DATE:~3,2%-%DATE:~6%
goto :setup
:Daydate
SET FDATE=%DATE:~4,2%-%DATE:~7,2%-%DATE:~10%
:setup

REN "BEX_CNTYBACKUP_*.xml" DailyBackup%FDATE%.xml

copy DailyBackup%FDATE%.xml Z:\
