If I try to use for %%f in (*.txt) do(...), it doesnt seems to process all the text files in the folder, rather it repeats the same file to do the processing.

for e.g if I have 2 text files(One.txt, Two.txt) in a folder, it repeats 2 times since it received 2 text entries, but the funniest part is it ALWAYS look for either One or Two. Even I tried to rename the first file it is processing, but the program doesnt go into 2 text file. instead it stopped the whole process.

Any idea how to get rid of this problem?

Alternatly I've an idea but not sure how to code it:

Simply create a text file by re-directing the output of dir /s command to a text file:
then read the text file and process the entry one by one.

Any one can help how to read a text file line by line until EOF.

Thanks a lot for any help

Cheers/RajaI USED these PIECE of code and found bug with For loop:

for %%f in (*.txt) do (
REM get the filemname
SET var=
set var=%%f

REM echo.%var%

REM so the rename
ren %var% xxx

REM I wanted to check which file is modified, hence I paused before I proceed to next text file
pause

move xxx archived/%var%

rem reset var before go to next file
rem set var=
)

I've tested with One.txt and Two.txt, the processing is unpredictable, either it takes only One.txt or Two.txt. Scary man.

Thanks for your assistance.Code: [Select]@echo off
REM example of for loop in batch file

REM write 4 lines to a file
echo line 1 > readme.txt
echo line 2 >> readme.txt
echo line 3 >> readme.txt
echo line 4 >> readme.txt

REM read them back in a loop
for /F "delims==" %%a in (readme.txt) do (
echo %%a
)

You need to put FOR /F. It indicates to FOR that whatever is between the parentheses is the source
of a series of lines of data to be read and processed.

without the "/F", what is between the parentheses is interpreted as a
series of ITEMS.

Code: [Select]for "delims==" %%a in (Apples Pears Oranges) do (
echo %%a
)

Output...

Apples
Pears
Oranges

single-quotes within the parentheses indicates that the data lines are
sourced from the output of a command. Without the single-quotes, FOR /F
tries to read a (text-)file named (whatever is within the parentheses)

To use wild cards like *.txt use double quotes.

Sometimes I use the output of

dir /b *.txt


My example:

Code: [Select]@echo off

REM write 4 lines to a file
echo line 1 > readme.txt
echo line 2 >> readme.txt
echo line 3 >> readme.txt
echo line 4 >> readme.txt


REM read them back in a loop


REM FOR EACH ITEM FOUND BY dir /b....
for /F "delims==" %%a in ('dir /b *.txt') do (

REM OR THIS LINE DOES SAME THING
REM note double quotes
REM for /F "delims==" %%a in ("*.txt") do (


REM echo file NAME
echo %%a

REM show file CONTENTS
type %%a

)

Hope this helps.

I suspect that as you are iterating around all files and you are changing the files, it will get confused (ie changing the order it encounters the files)
.
Your idea of putting the filelist into a text file is a good one as it will isolate you from the effect of these changes

GrahamHi Folks.

Thanks for helping me:

Here is the piece of code that is working(to benefit to others who require such a piece of code)

REM=============================================
@echo off
REM example of for loop in batch file

REM write all *.txt into readme(in sorting order by date)
dir *.txt /W/B/OD > readme

REM read them back in a loop
for /F "delims==" %%a in (readme) do (

echo %%a
rename %%a xxx.txt
pause
REM You can call other batch to process the file then rename back to original file
rename xxx.txt %%a
)
