For example:
There is a Txtsetup.sif file that contains two fields: [HiveInfs.Fresh] and [SourceDisksFiles].

I want to add a line of characters "AddReg = settings.inf,update" under [HiveInfs.Fresh].

Under the [SourceDisksFiles] field, add two lines of characters respectively:
settings.inf =1,,,,,,_x,3,,3
settings.reg =100,,,,,,,2,0,0

It should be noted that there are several lines of characters under the [HiveInfs.Fresh] and [SourceDisksFiles] fields themselves.

How to use batch processing to add the characters under these two fields? I am just learning batch processing, please give me some advice.

Requirement: This file is in ANSI encoding, and there should be no spaces at the beginning and end. (The processed file will delete blank lines)
@echo off&setlocal enableDelayedExpansion (for /f "eol=€ delims=" %%a in (Txtsetup.sif) do ( echo %%a if "%%a"=="" echo AddReg = settings.inf,update if "%%a"=="" ( echo settings.inf =1,,,,,,_x,3,,3 echo settings.reg =100,,,,,,,2,0,0 ) ))>han.ye move han.ye Txtsetup.sif

Hanyeguxing, the batch processing test was successful. But this batch processing removed the spaces at the beginning and end of the text to be added (Txtsetup.sif) as well as the blank lines in the middle of the text, but I want to keep these. How should I do it? Thank you for your help.

Also, I tested the following batch processing, but it's too slow, not as fast as yours, but this one doesn't delete blank lines. Please see:
……………………………………………………………………………………………………
@echo off
for /f "delims=" %%a in (TXTSETUP.SIF) do (
echo/%%a|findstr /xic:"" >nul && (
(echo/%%a
ehco settings.inf=1,,,,,,_x,3,,3
ehco settings.reg=100,,,,,,,2,0,0)>>newfile.txt
)||(echo/%%a>>newfile.txt)
)

copy /y newfile.txt TXTSETUP.SIF >nul && del newfile.txt
………………………………………………………………………………………
Thank you for your advice!

@echo off&setlocal enableDelayedExpansion
(for /f "tokens=1* delims=:" %%a in ('findstr /n .* "Txtsetup.sif"') do (
echo/%%b
set b=%%b
set b=!b: =!
if "!b!"=="" echo AddReg = settings.inf,update
if "!b!"=="" (
echo settings.inf =1,,,,,,_x,3,,3
echo settings.reg =100,,,,,,,2,0,0
)
))>han.ye
move han.ye Txtsetup.sif

Thanks! This batch processing was very successful. I'm researching how to customize the XP installation version, thank you for your help. In the future, I will still need to ask you for advice.
