    更改第2行变量的值。ini文件中不能包含有\或/字符

 @echo off
set "a=1" & set "b=50" & set "file=a.ini"
(for /f "delims=" %%a in ('findstr /n .* "%file%"') do (
    for /f "delims=" %%b in ("\%%a") do (
        set "str=%%~nb"
        setlocal enabledelayedexpansion
        if "!str:~,2!%%~xb" == "2:.%a%" (
            echo,!str:~2!.%b%
        ) else (
            if "!str:~,2!%%~xb" == "2:.%b%" (
                echo,!str:~2!.%a%
            ) else echo,!str:*:=!%%~xb
        )
        endlocal
    )
))>$
move $ "%file%"
pauseCOPY

或者这样试试：

@set @n=0; /* & echo off
set "a=1" & set "b=50" & set "file=a.ini"
cscript -nologo -e:jscript "%~0"<"%file%">$ "%a%" "%b%"
move $ "%file%"
pause & exit/b & rem */
var a = WScript.Arguments(0); b = WScript.Arguments(1);
var txt = WScript.StdIn.ReadAll();
var re = new RegExp("^(.*\\r?\\n.*\\.)("+a+"|"+b+")(\\s)", "")
txt = txt.replace(re, 
    function (s0,s1,s2,s3) {
        if (s2 == a){return s1+b+s3} else return s1+a+s3
    }
)
WScript.StdOut.Write(txt)COPY
