[文件操作] 批处理怎样获取本机MAC地址并替换掉指定文本中的MAC？

::::分离出机器的物理地址，并保存到 ( phyaddr.txt) 文件中
if exist phyaddr.txt del phyaddr.txt
if exist phyaddr1.txt del phyaddr1.txt
find "Physical Address" ipconfig.txt >phyaddr.txt
Set sc=1
Set scfile=phyaddr.txt
goto scan
::::多网卡时，扫描每个网卡MAC地址
:rescan1
Set sc=%sc%1

Goto scan
:rescan2
Set sc=%sc%1
Set scfile=phyaddr.txt
find /v "%strMac%" phyaddr1.txt >%scfile%
Goto scan
:scan
::::从(c:\phyaddr.txt)文件中取得物理地址字符串，并赋给变量"MacAddress"
for /f "skip=2 tokens=12" %%M in (%scfile%) do set strMac=%%M
::::以变量"strMac"为关键字搜索(iplist.txt)中相同的字符串行，并保存到(PCCfg.txt)
find "%strMac%" iplist.txt >PCCfg.txt
::::找出机器名(从"PCCfg.txt"中分离出 机器名字段，并赋给变量"CName")
for /f "skip=2 tokens=1" %%N in (PCCfg.txt) do set CName=%%N
if not "%CName%"=="" Goto found
::::支持最多扫描5个网卡
If "%sc%"=="11111" Goto failed
If "%sc%"=="1" Goto rescan1
if %scfile%==phyaddr.txt Goto rescan1
if %scfile%==phyaddr1.txt Goto rescan2
:found
ECHO 本机 MAC: %strMac%
ECHO 目标名称: %CName%
::::显示IP地址. (从"PCCfg.txt"中分离出 IP地址字段，并赋给变量"IPAddress")
for /f "skip=2 tokens=3" %%I in (PCCfg.txt) do set IPAddress=%%I
ECHO 目标地址: %IPAddress%
::::显示网卡MAC地址.(从"PCCfg.txt"中分离出 MAC地址字段，并赋给变量"MacAddress")
for /f "skip=2 tokens=2" %%M in (PCCfg.txt) do set MacAddress=%%M
ECHO 目标 MAC: %MacAddress%
