Increment a number in a file name
Carsten Bartels
I must write a little batch file wich download a picture from the web
every 5 minutes and save it like this: pic00001.jpg, pic00002.jpg, ...
I've got the programm wget to get the picture from the URL.
I don't know how to write a loop in a batchfile with a variable wich
will be incremented and written into the output-filename of wget.
please help.
thanks in advance!

I can give only a hint. Try somthing like this:
set nmbr=1
if not exist nmbr.log goto loop
type nmbr.log | env_str nmbr /inc 1
:loop
if %nmbr%==100 goto end
echo %nbr%
wget ftp.picture pic%nmbr%.jpg
env_str nmbr /inc 1
goto loop
:end
echo %nmbr% > nmbr.log
set nbr=
env_str is a small tool to modify environment variables. the "/inc 1"
switch increments the variable nmbr. In connection with the type
statement and a pipe the variable can be initialized.
env_str is freeware anc can be downloaded from my website.

This depends entirely on the operating system in use. You posted from
NT, so I'll assume that is the one you want the code for.
set number=0
:loop
set /a %number%+1
START your command(s) here - the filename is "pic%number%.jpg"
delay program here
goto loop

Hello Carsten
This is a pure DOS approach
I tested it in Win9x.
should work in NT/2000 to.
Creates Files pic00000.pic to pic99999.pic
CODE:
picount.bat
@echo off
set z=c:\archiv
set y=c:\temp.pic
set a=if not
set b=DO %a% exist
set c=for %%K IN
set d=%c% (9 8 7 6 5 4 3 2 1 0) %b%
set e=%c% (0 1 2 3 4 5 6 7 8 9) %b%
c:\
%a% exist %z%\*.* md %z%>nul
cd %z%
set f=set c0
%d% "pic%%K9999.pic" set z0=%%K
%f%=%z0%
%d% "pic%c0%%%K999.pic" set z0=%c0%%%K
%f%=%z0%
%d% "pic%c0%%%K99.pic" set z0=%c0%%%K
%f%=%z0%
%d% "pic%c0%%%K9.pic" set z0=%c0%%%K
%e% "pic%z0%%%K.pic" call makepic.bat %y% %%K
%c% (f e d b a c0 y z) DO set %%K=
set c=
remarks:
the wget-file is "c:\temp.pic"
the pic-archive is "c:\archiv".
change these values with set z/y=
parms a to f are just cosmetic for less coding.
parms c0 and z0 do the counting
a-f and c0+z0 should not be changed.
parms z+y define path and name of the pic-archive(z)
and the temorary pic (y).
Due to the many parms environment space shuold be
increased in config.sys
Both batches must be in a %PATH%-folder.
counter checks file with "9"at the end.
none of these files should be removed later on.
------------------------------------------
CODE
makepic.bat (called by picount.bat)
@echo off
if %z0%)==) goto end
copy %1 "pic%z0%%2.pic" > nul
echo File %z%\"pic%z0%%2.pic" was copied!
set z0=
:end
-------------------------------------------

Thank you very much. (And to all other, too!)
It works! (but it must be "set /a number=%number%+1")
BTW: The code was for NT.

Oh, sorry, it's me.
Now i've got the problem that the pictures are sorted like this:
pic1.jpg pic10.jpg pic11.jpg ... pic2.jpg pic20.jpg ...
is it possible to change the script to get file-names like this?:
pic00001.jpg pic00002.jpg ...
this doesn't work: set number=00000 ... set /a number=%number%+00001
BTW: I work with WinNT
Thanks.

This only counts 0 to 9 for me.
Does it count past 9 for anyone else?
========================================
Hey Carsten, try this batch counter too.
I didn't include an environment test, but that's easily done.
Also, make sure you have CHOICE in your path!
@echo off % Tested in Windows 98 %
if %Done%'==Yes' goto end
if !!!!!==%1 goto CopyFile
if '%1==' for %%? in (count done) do set %%?=
if '%1==' echo Press any key to pause, [C] to continue, or [Q] to quit.
for %%? in (0 1 2 3 4 5 6 7 8 9) do call %0 %1! %2%%?
if '%1==' set Done=
goto end
:CopyFile
set Count=%Count%!
::Change the "1" below to 60 for a 5 min. delay.
choice /c~cq /t~,1 >nul
if errorlevel 3 set Done=Yes
if errorlevel 3 goto end
if not !!!!!'==%count%' goto CopyFile
::Do whatever here.
echo "copy PicFile.jpg Pic%2.jpg"
:end
set Count=

When it's necessary to format that precisely, I generally switch to a
language that has a printf() function (C, AWK, Perl, etc.), at least
for the part that generates the string. See:
<http://gearbox.maem.umr.edu/~batch/multilingual.html> and following
pages for somewhat related examples.
I have also done leading zero counters in pure batch, and some of the
concepts may be useful, though I have not even looked at porting the
code to NT specific batch language:
<http://gearbox.maem.umr.edu/~batch/intrin1.htm#count>.

I am sorry Mr. Vargo, but you are utterly wrong.
My aprroach works for numbers 00000 to 99999,
On Win 9x and DOS-systems.
with exactly the code I posted and the condition
I stated.

Maybe I missed something, I'll try it again.

Here is a batch routine that will patch the variable %number% with
leading zeroes until the string is five characters long. It's slow,
but since you only need to run it every five minutes, it is probably
useful:
set number=%number%X
:next
set check=%number:~5,1%
if "%check%"=="X" goto done
set number=0%number%
goto next
:done
set number=%number:~0,5%
set check=
