[注册表类] 批处理怎么读取hosts文件中的IP来设置注册表？

@echo off
setlocal enabledelayedexpansion
::指定hosts所在目录
cd /d "C:\windows\system32\drivers\etc\"
for /f "tokens=2 delims=:" %%i in ('ipconfig ^| findstr "IPv4"') do set "localip=%%i"

for /f "eol=# delims=" %%j in ('type "hosts"') do echo %%j>>$$1
set n=1
for /f "tokens=1*" %%a in ($$1) do (
if !n! lss 3 (
echo %%a %%b>>$$2
) else (
echo %%a %%b>>$$3
)
set /a n+=1
)

set m=1
for /f "tokens=1*" %%s in ($$2) do (
if !m! equ 1 (
echo 读取%%s，执行将注册表下某项值设为%%t
) else (
echo 读取%%s，执行将注册表下某项值设为%%t
)
set /a m+=1
)

for /f "tokens=1*" %%e in ($$3) do (
if %localip% equ %%e (
echo 执行修改主机名为%%f
set "number=%%f"
echo 执行修改后三位!number:~-3!
pause
del $$* /s /q >nul
exit
)
)
echo 没有找到匹配项

del $$* /s /q >nul
pause
