Add counter value in Windows cmd script - windows

My script goes similar to this:
cd <Directory>
set counter = 1
for /r %%f in (*) do (
<Do task>
echo Task completed for file<counter> >> C:\log
counter++
)
I can't figure out how to use the actual counter value. If i use counter or %counter% it simply echoes the same string. How should i modify the counter lines in this case?

SET must be used with /A if you want to evaluate mathematical expressions. You also need to enable Delayed Expansion first by typing SETLOCAL ENABLEDELAYEDEXPANSION as the first line. Evaluation inside **FOR** loop is not done until the last iteration happens. But I modified the batch file so that the value of Counter is incremented in each iteration.
SETLOCAL ENABLEDELAYEDEXPANSION
#echo off
set /a counter=1
for /r %%f in (*) do (
echo Task Completed for file !counter! >> c:\log
set /a counter=!counter!+1
)

SET /A Variable_Number Math_symbol = Step(s)
set /a Var_Num+=1 -> Num_Var = Num_Var + 1 (Step)
set /a Var_Num-=1 -> Num_Var = Num_Var - 1 (Step)
set /a Var_Num*=2 -> Num_Var = Num_Var x 2 (Steps)
set /a Var_Num/=2 -> Num_Var = Num_Var : 2 (Steps)
In a Loop:
#echo off
set counter=0
:start-loop
set /a counter+=1
echo %counter% times...
:: or/and
echo %counter% times... >> %USERPROFILE%\Desktop\log.txt
timeout /t 1 >nul
goto :start-loop
Your example: (in 'FOR' loop)
SETLOCAL ENABLEDELAYEDEXPANSION
#echo off
set /a counter=1
for /r %%f in (*) do (
echo Task Completed for file !counter! >> C:\log.txt
echo Path to File: [ %%f ] >> C:\log.txt
set /a counter+=1
)

Compare array of numbers in a batch script

I'm trying to compare a sequence of 9 numbers (separated by ,) using a batch file.
The comparison is always made by the corresponding sequence like:
mPrevious[0] <-> mCurrent[0]
mPrevious[1] <-> mCurrent[1]
I need to know if at least one sequece have changed. In the example bellow, 234 changed to 230 and 146 to 149.
The sketch I have so far is:
setlocal ENABLEDELAYEDEXPANSION
#echo off
set mPrevious=229,234,235,127,58,0,131,133,146
set mCurrent=229,230,235,127,58,0,131,133,149
for /f "tokens=1,2,3,4,5,6,7,8,9 delims=," %%a IN ('echo !mPrevious!') do (
)
The number of entries (currently 9) might change in the future. But for now they are just 9.
I'm not sure what is the proper way to do it inside a batch script.
#echo off
title <nul && title ...\%~nx0
setlocal enabledelayedexpansion
set "_mPrevious=229,234,235,127,58,0,131,133,146"
set "_mCurrents=229,230,235,127,58,0,131,133,149"
echo/!_mPrevious!|find "!_mCurrents!" >nul && (
endlocal & echo\Nothing changed^!! & goto :EOF )
for %%i in (!_mPrevious!)do set /a "_i+=1+0" && call set "_mPrev_!_i!=%%~i"
for %%j in (!_mCurrents!)do set /a "_j+=1+0" && call set "_mCurr_!_j!=%%~j"
if !_i! neq !_j! endlocal & echo\Varyables have different lengths^!! & goto :EOF
for /L %%L in (1 1 !_j!)do if !_mPrev_%%~L! neq !_mCurr_%%~L! echo\!_mPrev_%%~L! updated to: !_mCurr_%%~L!
endlocal && goto :EOF
Outputs:
234 updated to: 230
146 updated to: 149
One simple way to do this only if necessary and only if both variable has same length:
Make a first comparison if the variables are the same, there was a change in the values:
echo/!_mPrevious!|find "!_mCurrents!" >nul && (
endlocal & echo\Nothing changed^!! & goto :EOF )
And a second if they continue with the same length:
if !_i! neq !_j! endlocal & echo\Variables have different lengths^!! & goto :EOF
Obs.: 1. I prefer replace [ ] to one simple _
Obs.: 2. Also, change i+= to _i+=1+0, where no need predefined set command: set i=0
The FOR token delimiters are: <SPACE> <TAB> <NBSP> , ; =
Therefore, you can put it into a FOR loop, but it would fail if the content contained * or ?.
#echo off
====SETLOCAL EnableDelayedExpansion EnableExtensions
set/a"#=cnt=0"
::Define lists
set "mPrevious=229,234,235,127,58,0,131,133,146"
set "mCurrent=229,230,235,127,58,0,131,133,149"
FOR %%P in (!mPrevious!) do (
FOR %%C in (!mCurrent!) do (
if !cnt! equ !#! echo(%%P %%C
set/a"cnt+=1"
)
set/a"cnt=0,#+=1"
)
This is an approach using some self-expanding code:
#echo off
setlocal EnableDelayedExpansion
rem // Define constants here:
set "mPrevious=229,234,235,127,58,0,131,133,146"
set "mCurrents=229,230,235,127,58,0,131,133,149"
rem // Initialise auxiliary variables and indexes:
set "nPrevious=,%mPrevious%" & set /A "i=0"
set "nCurrents=,%mCurrents%" & set /A "j=0"
rem // Convert lists to arrays using self-expanding code:
set "_=%nPrevious:,=" & set /A "i+=1" & set "nPrevious[!i!]=%"
set "_=%nCurrents:,=" & set /A "j+=1" & set "nCurrents[!j!]=%"
rem // Verify availability of arrays:
> nul 2>&1 set nPrevious[ || set /A "i=0"
> nul 2>&1 set nCurrents[ || set /A "j=0"
rem // Determine minimal and maximal count:
if %j% gtr %i% (set /A "k=i, l=j" & set "_=#") else (set /A "k=j, l=i" & set "_=")
rem // Compare corresponding elements:
for /L %%K in (1,1,%k%) do if !nPrevious[%%K]! neq !nCurrents[%%K]! (
echo [%%K]: !nPrevious[%%K]! -^> !nCurrents[%%K]!
)
rem // Return removed or added elements:
set /A "k+=1" & for /L %%K in (!k!,1,%l%) do if defined _ (
echo [%%K]: --- -^> !nCurrents[%%K]!
) else (
echo [%%K]: !nPrevious[%%K]! -^> ---
)
endlocal
Sample output, relying on the data of the question:
[2]: 234 -> 230
[9]: 146 -> 149

Batch Script Iterative form

I have a batch script which :
check the files in a directory and check if it exists in another
directory and it should not exists there
count each file with a specific format, there should be just one of each
if both of the above statement is true then generate a success file.
Below is my code which is working fine:
SET /A file1=file2=Val=0
SET /A FileE=1
set /a flagname=1
for %%A in (*ABC*.txt) do set /a file1+=1
for %%A in (*XYZ*.txt) do set /a file2+=1
for %%i in ("*") do if exist "Processed\%%~nxi" SET /A FileE=0
SET /A Val=%file1%*%file2%*%FileE%
if %Val% EQU 1 (
echo SUCESS>Sucess.txt
SET Flag=Sucess
echo %Flag%) else (
if %file1% EQU 0 ( echo Missing ABC.txt files >> Error.txt)
if %file1% GTR 1 ( echo More than 1 ABC.txt files >> Error.txt)
if %file2% EQU 0 ( echo Missing XYZ.txt files >> Error.txt)
if %file2% GTR 1 ( echo More than 1 XYZ.txt files >> Error.txt)
(for %%i in ("*") do if exist "Processed\%%~nxi" echo(File Exists in
Processed
Folder %%~i)>>Error.txt
SET Flag=FAILURE
echo %Flag%)
My problem is how to transform above code to iterate over a list of number of files like 100 ? Below is the code which I tried :
#echo off
setlocal enable delayed expansion
Set Filen[0]=ABC*.txt
Set Filen[1]=XYZ*.txt
SET /A Val=1
SET /A File1=0
FOR /l %%G in (0,1,1) Do (
echo !Filen[%%G]! hi
set File1=0
echo %file1% Count
for %%A in (!Filen[%%G]! ) do (
set File1=!File1!+1
echo %%A %file1%)
)
Put your search words in a string and iterate over it:
Set "Search=ABC DEF XYZ"
For %%A in (%Search%) do (
Or in a file and read one by one
For /f "usebackq" %%A in ("Search.txt") Do (
With this file Search.txt
ABC
DEF
XYZ
In the environment
> tree a:\ /F
Auflistung der Ordnerpfade für Volume RamDisk
A:\
└───Test
│ ABC_123.txt
│ DEF_456.txt
│ Search.txt
│
└───Processed
The following batch
:: Q:\Test\2018\07\01\SO_51120147.cmd
#Echo off & Setlocal EnableDelayedExpansion
Set "BaseDir=A:\Test"
Set Err=^>^> "Error.txt" Call Echo=[%%date%% %%time%%]
PushD "%BaseDir%" || (%Err% can't locate %BaseDir% & Pause &Goto :Eof)
%Err% Job %~f0 started by %USERNAME%
Set " Flag=Sucess"
:: Uncomment for string variant
:: Set "Search=ABC DEF XYZ"
:: For %%A in (%Search%) do (
:: use the file variant
For /f "usebackq" %%A in ("Search.txt") Do (
Set Cnt=0
For %%B in (%%A*.txt) Do Set /A Cnt=1
if !Cnt! NEQ 1 (
%Err% Count of %%A*.txt file=[!Cnt!]
SET Flag=FAILURE
)
)
For %%A in (*) do if exist "Processed\%%~nxA" (
%Err% File %%A does exist in Processed Folder
Set Flag=FAILURE
)
%Err% Job %~f0 terminated with %Flag%
Yields this output:
> type A:\Test\Error.txt
[2018-07-01 13:10:34,43] Job Q:\Test\2018\07\01\SO_51120147.cmd started by LotPings
[2018-07-01 13:10:34,45] Count of XYZ*.txt file=[0]
[2018-07-01 13:10:34,47] Job Q:\Test\2018\07\01\SO_51120147.cmd terminated with FAILURE
EDIT: Explanation of the somehow tricky line:
Set Err=^>^> "Error.txt" Call Echo=[%%date%% %%time%%]
To not have to pre/append every line which should go to the error log with
the redirection and a (fixed) file name I put these together with the
echo command and a [date time] stamp into a variable.
To avoid immediate interpretation when setting the variable, the '>' have to
be esaped with a caret, and to delay the expansion of the %-signs these have
to be doubled. (otherwise each log entry had the same date time)
To force expansion of date time when echoing the (pseudo) call is neccessary.

How to use % or ! in batch script

I write script like this:
#ECHO OFF
setlocal EnableDelayedExpansion
set "remove=ABC"
echo. %remove%
Set FILENAME="456_789_ABC00011092_789_EFGHIK_56893.mpg"
for %%a in (%FILENAME:_=" "%) do (
set TEN=%%a
echo. %AB%
set "remove_1=ABC"
echo. %remove_1%
Set _TEN=!TEN:%remove%=!
echo. %_TEN%
Set i=0
IF !_TEN! NEQ !TEN! (
set /A i+=1
set "String[!i!]=%%~a"
)
)
pause
exit
Why echo. %AB% echo. %remove_1% result is
I replace % by !. It's work fine but command Set _TEN=!TEN:!remove_1!=! not run
Edit - (from the additional question currently posted as an answer)
When I use FindStr command like this:
for %%a in (%FILENAME:_=" "%) do (
echo %%a | findstr /I /R /C:"ABC" >nul
ECHO %errorlevel%
if "%errorlevel%" equ "0" (
set /A i+=1
set "String[!i!]=%%~a"
)
)
Why errorlevel always = 0
%AB% has not been defined within your posted script, so as it has no value will not be echoed, you will just get an empty line due to the . after echo. Because remove_1 is being set within the loop, (code block), you should be using the delayed expansion syntax, Echo !remove_1!. It is the same for echo. %_TEN%, i.e. Echo !_TEN!, and would have been Echo !AB! had it previously been defined. In order to get the double expansion needed to Set your _TEN variable, you could use a pseudo Call:
#Echo Off
SetLocal EnableDelayedExpansion
Set "FILENAME=456_789_ABC00011092_789_EFGHIK_56893.mpg"
For %%A In ("%FILENAME:_=" "%") Do (
Set "TEN=%%A"
Echo. !AB!
Set "remove_1=ABC"
Echo !remove_1!
Call Set "_TEN=!TEN:%%remove_1%%=!"
Echo !_TEN!
Set "i=0"
If "!_TEN!" NEq "!TEN!" (
Set /A i+=1
Set "String[!i!]=%%~A"
)
)
Pause
Exit /B
In your second related question, initially posted as an answer and now added as an edit to your original question; because the error level is being set within the loop, (code block), you should be using the delayed expansion syntax, !errorlevel!
#Echo Off
SetLocal EnableDelayedExpansion
Set "FILENAME=456_789_ABC00011092_789_EFGHIK_56893.mpg"
For %%A In ("%FILENAME:_=" "%") Do (
Echo %%A | FindStr /IRC:"ABC" >Nul
Echo !errorlevel!
If "!errorlevel!"=="0" (
Set /A i+=1
Set "String[!i!]=%%~A"
)
)
Set String[
Pause
Exit /B
Or if you don't need to Echo each error level to the screen, you can use a conditional statement &&:
#Echo Off
SetLocal EnableDelayedExpansion
Set "FILENAME=456_789_ABC00011092_789_EFGHIK_56893.mpg"
For %%A In ("%FILENAME:_=" "%") Do (
Echo %%A | FindStr /IRC:"ABC" >Nul && (
Set /A i+=1
Set "String[!i!]=%%~A"
)
)
Set String[
Pause
Exit /B

how to compare numeric variables in batch files

why doesn't this work?
SET FIRST=""
SET COUNT=0
FOR %%F IN (dir *.png) DO (
IF %COUNT% NEQ 0 GOTO _skip
SET FIRST=%%F
:_skip
ECHO "%%F",
SET /A COUNT=COUNT+1
)
It sets FIRST to the last *.png because the IF condition fails, because COUNT - although is incremented by set /A, the IF %COUNT% doesn't ever work. Very frustrating.
Don't need to count, just do goto skip after echo line.
#echo off
for /f "delims=" %%f in ('dir /b *.png') do (
rem :: you can use "echo %%f" instead of "set first=%%f"
set first=%%f
goto _skip
)
:_skip
echo %first%
you mixing two things to scan folder.
Here is the second way:
#echo off
for %%f in (*.png) do (
set first=%%f
goto _skip
)
:_skip
echo %first%
exit /b 0
If you need absolutely to count, here is the way to skip with count. As stated in comment, you need to enable delayedExpansion
#echo off
set count=1
for %%f in (*.png) do (
set first=%%f
setlocal enabledelayedexpansion
if "!count!"=="1" goto _skip
endlocal
set /a count+=1
)
:_skip
echo !first!

How to get the value from a dynamic variable in windows batch file

I am using Microsoft Windows XP [Version 5.1.2600]
Trying to do this.
Trying to create the variable dynamically and then read the value out of that variable in a loop.
#ECHO off
SET SQL1=TEST
SET SQL2=TEST1
SET SQL3=TEST2
SET SQL=SQL
SETLOCAL ENABLEDELAYEDEXPANSION
SET /A number=0
FOR /l %%A IN (1,1,3) DO (
SET /A number = number + 1
echo !number!
echo %SQL%!number!
)
endlocal
Output should be
1
test
2
test2
3
test3
I am getting
C:\temp>c.bat
1
SQL1
2
SQL2
3
SQL3
Please help!
Ugh.
First way (note that instead of your number variable, it uses the loop counter variable %%A):
#ECHO off
SET SQL1=TEST
SET SQL2=TEST1
SET SQL3=TEST2
SETLOCAL ENABLEDELAYEDEXPANSION
SET /A number=0
FOR /l %%A IN (1,1,3) DO (
SET /A number = number + 1
echo !number!
echo !SQL%%A!
)
endlocal
Second way (ugly but it does what you want):
#ECHO off
SET SQL1=TEST
SET SQL2=TEST1
SET SQL3=TEST2
SETLOCAL ENABLEDELAYEDEXPANSION
SET /A number=0
FOR /l %%A IN (1,1,3) DO (
SET /A number = number + 1
echo !number!
for %%i in (!number!) do (echo !SQL%%i!)
)
endlocal
