[文本处理] 批处理如何从文本里随机提取一行替换到另一个文本？

A文本如何下
a.txt
ethernet0.address = "a2:1D:7CD:AE:AE"
ethernet0.address = "50:16:82:8B:67:36"
ethernet0.address = "F4:FE:16:C9:64:B6"
ethernet0.address = "A2:07:B1:7A:15:47"
ethernet0.address = "36:44:6C:36:1E:C5"
ethernet0.address = "B0:05:89:FE:E1:46"

B.txt
ethernet1.wakeOnPcktRcv = "FALSE"
ethernet1.addressType = "generated"
ethernet1.linkStatePropagation.enable = "TRUE"
ethernet0.address = "66:5A:DB:0C:A1:4D"
ethernet1.pciSlotNumber = "-1"
ethernet1.generatedAddress = "00:0c:29:59:ac:e9"
ethernet1.generatedAddressOffset = "10"
tools.remindInstall = "TRUE"
floppy0.present = "FALSE"
tools.syncTime = "FALSE"

批处理如何实现从a.txt文本里随机或者顺序取一行替换B.txt里的ethernet0.address = 开头的这行，包括双引号？本人小小白，研究半天sed还有find貌似实现有点困难，请高人指点，主要是还包括特殊符号

2楼最后一行改成这样试试：

sed -i "/^ethernet0/ s/.*/ethernet0.address = \"%NewMAC%\"/" "%FileB%"

感谢大神！win10下测试好用，谢谢

#&cls&@Powershell "& {[ScriptBlock]::Create("'#' + ([io.file]::ReadAllText('%~f0',[text.encoding]::Default))").Invoke()}" & pause & exit

$a_txt = 'a.txt'
$b_txt = 'b.txt'
$text_a = [io.file]::ReadAllLines($a_txt,[text.encoding]::Default)|?{$_ -ne ''};
$text_b = [io.file]::ReadAllLines($b_txt,[text.encoding]::Default);

$rnline = Get-Random -InputObject $text_a -Count 1;
$text_b -replace '^ethernet0.address =.*',$rnline|Set-Content -Path $b_txt -Encoding Default

    刚刚测试了一下，“”没有加进去，不知道应该如何改进？

请参考Q-04和Q-05把bat文件和ini文件都保存为ANSI编码：

命令行工具 sed.exe 下载地址：
http://bcn.bathome.net/s/tool/index.html?key=sed

@echo off
set "FileA=A.txt"
set "FileB=B.txt"
for /f %%a in ('type "%FileA%" ^| find /c /v ""') do (
    set "RowNum=%%a"
)
set /a RndNum=%random%%%(%RowNum%-1+1)+1
for /f "tokens=3" %%a in ('type "%FileA%" ^| sed -n "%RndNum%p"') do (
    set "NewMAC=%%~a"
)
sed -i "/^ethernet0/ s/.*/ethernet0.address = "%NewMAC%"/" "%FileB%"
