Changing a flag in the ini file from batch script - batch-file

Question

I have a script which will check if the file names and the content of the files are same or not, below is the code and it is working fine
ECHO OFF
CLS
for %%i in (C:\Users\f1ym41a\Documents\deep\*.DAT) do (
fc C:\Users\f1ym41a\Documents\deep\MOVE.DAT %%i > NUL
if errorlevel 1 (
CALL :error
echo C:\Users\f1ym41a\Documents\deep\MOVE.DAT and %%i are different >>output.log
) ELSE (
CALL :next
echo C:\Users\f1ym41a\Documents\deep\MOVE.DAT and %%i are same >>output.log
)
timeout 5
)
PAUSE
What i need to do is if the file names are same then it will change the flag in the ini file to 1. Below is the ini file (deep.ini)
[INI]
flag = 0
Since i am new to batch scripting. Can somebody help me out with this?

Answer 1

You can try with replacer.bat:
call replacer.bat move.dat "flag = 0" "flag = 1"

Answer 2

This is an easy to achieve task with using JREPL.BAT written by Dave Benham which is a batch file / JScript hybrid to run a regular expression replace on a file using JScript.
#echo off
if not exist "%USERPROFILE%\Documents\deep\MOVE.DAT" goto :EOF
if not exist "%~dp0jrepl.bat" goto :EOF
call "%~dp0jrepl.bat" "^(flag *= *)0" "$11" /F "%USERPROFILE%\Documents\deep\MOVE.DAT" /O -
The batch file first checks if the file to modify exists at all and immediately exits if this condition is not true, see Where does GOTO :EOF return to?
The batch file JREPL.BAT must be stored in same directory as the batch file with the code above. For that reason the batch file checks next if JREPL.BAT really exists in directory of the batch file and exits if this condition is not true.
The meaning of the regular expression search string is:
^ ... find at beginning of a line
(...) ... a string referenced in replace string with $1 to keep this part of found string unmodified
flag ... case-sensitive the string flag
 * ... with 0 or more spaces
= ... and an equal sign
 * ... and once more 0 or more spaces
0 ... and the character 0.
The replace string back-references the found string between beginning of line and character 0 with $1 and replaces 0 by 1.
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.
call /? ... explains also %~dp0 ... drive and path of argument 0 which is the batch file path always ending with a backslash.
echo /?
goto /?
if /?
jrepl.bat /?

:: 1st need remove some possible space in the string to got more precision
when compare them: "flag = 0" will became "flag=0", no
space and no tab.
:: 2nd for to do this, use this "' (2 characters) to set a variable that
use "=" to string instead a special character,
by set "'=flag=0" (very old technical!)
:: 3rd treat equal, treat tab character, and to remove it, because some time
this is a invisible and possible character that can eventually occur
in file dat, see in this question 10878138
:: 4th Compare the strings by string from file by file, line by line...
:: finely You need replace line in the file (.dat or .ini) this part I´m really confuse, but the code are above, sorry if my error!
Obs: use the conversion of this "flag = 0" this this one "flag=0", only for processing comparatives operation, wend the %%i match flag = 0 then only changed to replace to files by flag = 1, bat, a specific thing here is the command fc are comparing %%i, by the same file in looping for with no other file.
#echo off && setlocal EnableExtensions EnableDelayedExpansion
set "'=flag=0"
set _file_new_flag1="%temp%\Flag1.dat"
set _path_to_dats=C:\Users\f1ym41a\Documents\deep\

cd /d "!_path_to_dats!"
for /f "tokens=* delims= " %%x in ('dir /o-d /on /b "*.dat"') do (
if defined _file_new_flag (

endlocal & goto :_end_of_file_:

call set "_to_compare=!_to_compare: =!"
for /f "tokens=* delims=" %%I in ('echo/%_tab%') do call set "_to_compare=!_to_compare:%%I=!"
if ["!_to_compare!"] equ ["%'%"] (

So sorry about my English.
