添加第二IP，Debian9修改interfaces总是不成功，只好用NetworkManager，好用多了。

apt-get install network-manager; 
nano /etc/NetworkManager/NetworkManager.conf; # false --> true
nmtui; # 添加第二IP，DNS等

NetwrikManager和原有的network兼容性不好，重启后需要再次重启网络服务

nmcli con down ens32; nmcli con up ens32;

@echo off
set itime=0

:start
for /f "tokens=2 delims==" %%a in ('wmic path Win32_PerfFormattedData_PerfOS_Processor get PercentProcessorTime /value^|findstr "PercentProcessorTime"') do set UseCPU=%%a
if %UseCPU% gtr 60 set /a itime=%itime%+1
if %UseCPU% lss 40 set itime=0
if %itime% gtr 30 goto vmrestart
choice /t 60 /d y /m "%date% %time% CPU %UseCPU% %itime% Waiting 60s"
goto start

choice /t 10 /d y /m "%date% %time% Somthing wrong, to end"
goto end

:vmrestart
choice /t 600 /d y /m "%date% %time% Restart finished, to start again"
set itime=0
goto start

:end
pause

choice 代替 ping 执行 sleep，看起来舒服点儿

@echo off
setlocal EnableEelayedExpansion
for /l %%i in (1,1,7) do (
    taskkill /f /im xxx.exe
    choice /t 3 /d y /n
    start "" "C:\xxx.exe"
    choice /t 3600 /d y /m "!date! !time! _%%i_ Wainting 3600s?"
)
pause

设置要永久加入到path环境变量中的路径

set My_PATH=c:\swds\software\cmder
set PATH=%PATH%;%My_PATH%
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v "Path" /t REG_EXPAND_SZ /d "%PATH%" /f
