I want to search string from right side .
For example =File be like file.c

content be like
if(a>10)
const char abc[] = {"NEL1.19"};

if(b>10)
const char abc[] = {"LME1.19"};



In my file abc[] is more than one time.if I find the string using abc[] it update the last abc[] in the file.so I thought to serach half string {"NEL1. from right side . then try to update the value by 1

What I have tried:

@Echo on

    Cd /d D:\
	setlocal enabledelayedexpansion
	set "file=newabc.c"
	
	for /F "tokens=1,* delims==" %%i in ('findstr " = {"NEL1.*"   " newabc.c') do (
	::{"*BLM1.*" xyz.c')
    set "versionVar=%%~i"
    set "versionVal=%%~j"
	echo %versionVal%
	set demo=%versionval:~7,5%
	set check=%demo:~0,-3%
	echo %check%
	::set "string=!versionVal:~2,5!"
	set /a sequence=!check!+1
	echo %sequence%
	)

	for /f "tokens=1,*delims=]" %%i in ('type "%file%" ^| find /v /n "" ^& break^>%file%') do (
    set "line=%%j"
    if "!line!" == "!versionVar!=!versionVal!" set line=!versionVar!= !sequence!
    echo(!line!>>!file!
	
	)

And?
What does it do that you didn't expect, or not do that you did?
What have you tried to do to find out why?
Are there any error messages, and if so, where and when? What did you do to make them happen?

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

As you have been struggling with batch files for some time now, maybe you should consider another approach, batch files are not really suitable for what you want.
I would recommend using C#, VB.NET or PowerShell, as .NET makes these kind of things much easier.

@RickZeeland,I am new for batch file thatswhy I am facing issues like that. This is the last issue. If you have any solution please help me out from this issue.

Guess it's easy for me to say, as I have enough experience with both batch files and .NET
:)

As I am rusty with windows/dos batch files, I did a google search: windows batch file pattern matching - Google Search[^]

This looks like what you may be looking for: File name pattern matching in Windows command line[^]

Digging a bit deeper: findstr examples - Google Search[^]

Found this: MS-DOS and Windows command line findstr command[^]
