主机实现hostname的修改原理：

　　修改注册表中的值：

　　　　hklm\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName 下的 ComputerName

　　　　hklm\SYSTEM\CurrentControlSet\Control\ComputerName\ActiveComputerName 下的 ComputerName

　　　　hklm\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters  下的 Hostname

　　　　hklm\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters 下的 NV Hostname

 

bat脚本实现：

@echo off
if not "%OS%"=="Windows_NT" goto END
if "%1"=="" (
    set INFO=echo &&set skip=0&&set err=0
) else if "%1"=="/?" (
    set INFO=echo && set skip=1&&set err=0&&goto DESC
) else  if "%1"=="-q" (
    set INFO=echo &&set err=1&&goto ERR
) else  if "%1"=="-r" (
    set INFO=echo &&set err=1&&goto ERR
) else (
    set name=%1 && goto CHANGE
)
