用批处理修改host文件的代码

@echo 127.0.0.1 baidu.com >>C:WindowsSystem32Driversetchosts
这样就是换一行写入。
如果还想换一行,就写:
 
@echo. >>C:WindowsSystem32Driversetchosts
@echo 127.0.0.1 baidu.com >>C:WindowsSystem32Driversetchosts
@echo 192.168.4.201 ibmrac1 >>C:WindowsSystem32Driversetchosts
@echo 192.168.4.202 ibmrac2 >>C:WindowsSystem32Driversetchosts
@echo 192.168.4.203 vip-ibmrac1 >>C:WindowsSystem32Driversetchosts
@echo 192.168.4.204 vip-ibmrac2>>C:WindowsSystem32Driversetchosts
@echo 172.16.1.53 ssosvr>>C:WindowsSystem32Driversetchosts


 
@echo off
set stHosts=172.16.1.53 ssosvr
FOR /F "eol=# tokens=1 delims=" %%i in (%systemroot%system32driversetchosts) do if "%stHosts%"=="%%i" exit
echo %stHosts%>> %systemroot%system32driversetchosts



由于测试需要经常修改本机host,可以用脚本修改:
分别做两个批处理,一个内网,一个外网,用的时候切换运行即可
如内网.bat
 
cd /d %windir%system32driversetc
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 "szshequ.com" //寻找制定记录删除
if %errorlevel%==1 (echo %1 %2 >>hosts)
:end

type C:WINDOWSsystem32driversetchosts
type C:WINDOWSsystem32driversetchosts | find "szshequ.com" && goto yes
::echo 192.168.2.188 szshequ.com >> ""
