使用Windows Batch替换文本文件中的一行

Question

I have text file that has the following contents

status=y

I need to change it to

status=n

using a windows batch script

I tried this but I get a syntax error

setlocal enabledelayedexpansion
set INTEXTFILE=status.txt
set OUTTEXTFILE=t.txt
set SEARCHTEXT='status=y'
set REPLACETEXT='status=n'
set OUTPUTLINE=
for /f "tokens=1,* delims=" %%A in ( '"type %INTEXTFILE%"') do (
SET string=%%A
SET modified=!string:%SEARCHTEXT%=%REPLACETEXT%!
echo !modified! >> %OUTTEXTFILE%
)
del %INTEXTFILE%
rename %OUTTEXTFILE% %INTEXTFILE%

Answer 1

Test this on a sample file.

@echo off
type status.txt|repl "status=y" "status=n" L >temp.tmp
move temp.tmp status.txt >nul

The above uses a helper batch file called repl.bat - download from: https://www.dropbox.com/s/qidqwztmetbvklt/repl.bat

Place repl.bat in the same folder as the batch file or in a folder that is on the path.
