用批处理修改host文件的代码
@echo 127.0.0.1 baidu.com >>C:\Windows\System32\Drivers\etc\hosts
这样就是换一行写入。
如果还想换一行，就写：
代码如下:
@echo. >>C:\Windows\System32\Drivers\etc\hosts
@echo 127.0.0.1 baidu.com >>C:\Windows\System32\Drivers\etc\hosts
@echo 192.168.4.201 ibmrac1 >>C:\Windows\System32\Drivers\etc\hosts
@echo 192.168.4.202 ibmrac2 >>C:\Windows\System32\Drivers\etc\hosts
@echo 192.168.4.203 vip-ibmrac1 >>C:\Windows\System32\Drivers\etc\hosts
@echo 192.168.4.204 vip-ibmrac2>>C:\Windows\System32\Drivers\etc\hosts
@echo 172.16.1.53 ssosvr>>C:\Windows\System32\Drivers\etc\hosts
@echo off
set stHosts=172.16.1.53 ssosvr
FOR /F "eol=# tokens=1 delims=" %%i in (%systemroot%\system32\drivers\etc\hosts) do if "%stHosts%"=="%%i" exit
echo %stHosts%>> %systemroot%\system32\drivers\etc\hosts
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
代码如下:
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 "szshequ.com" //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 "szshequ.com" && goto yes
::echo 192.168.2.188 szshequ.com >> ""
echo 192.168.2.188 szshequ.com >> C:\WINDOWS\system32\drivers\etc\hosts
echo 192.168.2.188 www.szshequ.com >> C:\WINDOWS\system32\drivers\etc\hosts
echo 192.168.2.188 bbs.szshequ.com >> C:\WINDOWS\system32\drivers\etc\hosts
