Please help me....experts

Thanks !K ,,but it was not working .. i tweaked the code but still not working

I saved the example file and code into into test.cmd.. but stilll not working

Below was the output of executation...

C:\>test.cmd
line # is
string is ""
Press any key to continue . . .

The batch is tested on a sample output from the first post.
Give the real output file, preferably as (.ZIP +) .UUE in [code] tag

Hi The Out file is the same real output file which as i pasted previously.....

Please help in to obtain the output..

Probably the real strings have spaces at the end. Modify the code so
for /f "delims=:" %%n in ('findstr /b /n /c:"Driver is running." %output%') do set /a number=%%n-1

Thanks !k, I changed as per instruction now i am able to ger the line number and not the string. Output as below
----------------------------------------------------------------------------------------------------------------
C:\>test.cmd

C:\>set "output=c:\dev.txt"

C:\>for /F "delims=:" %n in ('findstr /b /n /c:"Driver is running." c:\dev.txt')
do set /a number=%n-1

C:\>for /F "tokens=2,* delims=:" %s in ('findstr /b /n /c:"Name:" c:\dev.txt |fi
ndstr /b /c:"6:Name:"') do set "string=%t"

C:\>echo line # is 6
line # is 6

C:\>echo string is ""
string is ""

Please help me out of the issue !K

May be forum not transmit any special characters in your output file.
Find a way to pass the output file unchanged (archive, UUEncode)

Could you let us know what you are expected from previous reply, I am unable to get you what your requesting..


1) I would like to use a string which exist at n th line number of data file(file containing lines of words) .
2)And to parse the exact data what i need for further operations( ":" symbol to separate left and right data to use

Example:
File data as below:
-----------------------------FILE DATA_START-----------------------------
aASA
ASAS
ASAS
Name: Wireless 1111 (VE-OD-APSH) Mobilephone Broadcast Card-Mini AEMN (COM23)
ASASAS
ASASSSA
ASASSA
-----------------------------FILE DATA_ENd-----------------------------

1>In the above I need fourth line data .. Let us say if u say line number 4, i need to get that data
2>In the current line I need to split the data by symbol ":" , Left side and right side, which i can use for further operations.
