使用批处理修改本机HOST的方法

cd /d %windir%\system32\drivers\etc
del hosts.bak     //删除原来备份文件
ren hosts hosts.bak   //备份现在host
for /f "eol=# tokens=1,2" %%i in (hosts.bak) do call :checkvalue %%i %%j
goto end
:checkvalue
echo %2 | find /i "jquerycn.cn"    //寻找制定记录删除
if %errorlevel%==1 (echo %1 %2 >>hosts)
:end

type C:\WINDOWS\system32\drivers\etc\hosts
type C:\WINDOWS\system32\drivers\etc\hosts | find "jquerycn.cn" && goto yes
::echo 192.168.2.188 jquerycn.cn >> ""
