set sp1=host助手

set hostsfile="%SYSTEMROOT%System32Driversetchosts"

title %sp1%

color 5f

:mainmenu

echo %sp0%

echo %sp1%

echo %sp0%

echo 1.编辑hosts 2.恢复hosts

echo 3.打开hosts文件 4.退出

echo.

set input=

set /p input=请选择：

if "%input%" == "" goto :mainmenu

if "%input%" =="1" goto :writehost

if "%input%" =="2" goto :recovery

if "%input%" =="3" goto :showhosts

if "%input%" =="4" goto :endtime

echo.

:writehost

cls

echo %sp0%

echo %sp0%

echo 120.0.0.1 >> "%hostsfile%"

echo 编写完毕

echo %sp0%

echo %sp0%

echo 任意键回到主界面

echo.

pause >nul

goto :mainmenu

:recovery

cls

echo %sp0%

echo %sp0%

echo # Copyright (c) 1993-2009 Microsoft Corp.>hosts

echo #>>hosts

echo # This is a sample HOSTS file used by Microsoft TCP/IP for Windows.>>hosts

echo #>>hosts

echo # This file contains the mappings of IP addresses to host names. Each>>hosts

echo # entry should be kept on an individual line. The IP address should>>hosts

echo # be placed in the first column followed by the corresponding host name.>>hosts

echo # The IP address and the host name should be separated by at least one>>hosts

echo # space.>>hosts

echo #>>hosts

echo # Additionally, comments (such as these) may be inserted on individual>>hosts

echo # lines or following the machine name denoted by a '#' symbol.>>hosts

echo #>>hosts

echo # For example:>>hosts

echo # For example:>>hosts

echo #>>hosts

echo.>>hosts

copy hosts C:WindowsSystem32driversetc

del hosts

echo hosts已恢复完毕

echo %sp0%

echo %sp0%

echo 任意键回到主界面

goto :mainmenu

:showhosts

cls

start "" %hostsfile%

goto :mainmenu

:endtime

exit

第二种：通过文件内容复制来恢复修改的hosts

echo off

chcp 65001

set sp0=------------------------

set sp1=host助手

set hostsfile="%SYSTEMROOT%System32Driversetchosts"

title %sp1%

color 5f

:mainmenu

cls

echo %sp0%

echo %sp1%

echo %sp0%

echo 1.编辑hosts

echo 2.查看hosts

echo 3.退出

echo.

set input=

set /p input=请选择：

if "%input%" == "" goto :endtime

if "%input%" =="1" goto :writehost

if "%input%" =="2" goto :showhosts

if "%input%" =="3" goto :endtime

echo.

:writehost

copy %hostsfile% G:

echo 备份完毕

echo %sp0%

echo 120.0.0.1 >> "%hostsfile%"

echo %sp0%

echo 编写完毕，任意键恢复hosts

pause > nul

goto:back

:showhosts

start "" %hostsfile%

:endtime

exit /B

:back

copy G: %hostsfile%

echo 编写完毕，任意键回到主菜单

pause > nul

goto:mainmenu
