Win32 CMD批处理命令

1. win32批处理下，另开一个console执行进程X

使用start [/K|/C]，示例：

//--------------------------------------------------------------------------------------
//example 1: 新开console，执行dir命令完毕后，不自动关闭console
start cmd /K dir 

//--------------------------------------------------------------------------------------
//example 2: 新开console，执行dir命令完毕后，自动关闭console
start cmd /C dir 

//--------------------------------------------------------------------------------------
//example 3: 完整示例
start /D D:demo-devdev_nativedemoICEx64Release cmd /K demoICE.exe server
start /D D:demo-devdev_nativedemoICEx64Release cmd /K demoICE.exe client

注意：start命令是不会拥塞当前控制台的.bat执行的。

2. 指定start的启动目录

使用start /D，示例如下：

start /D c:

3. 与linux后台运行(&)等价的start操作

使用start /b，示例如下：

in win32 console:
start /b iperf.exe > c:iperf_multicast_server_logfile.txt

in linux console:
/root/iperf1.7 > /root/iperf_multicast_client_logfile.txt &

4. 使用python脚本同时启动多console进程

2. https://stackoverflow.com/questions/15899798/subprocess-popen-in-different-console
3. https://docs.python.org/2/library/subprocess.html

示例如下：

//example 1:
from subprocess import Popen,CREATE_NEW_CONSOLE
Popen('cmd',creationflags=CREATE_NEW_CONSOLE)

//--------------------------------------------------------------------------------------
//example 2:
from sys import executable
from subprocess import Popen,CREATE_NEW_CONSOLE
Popen([executable,'script.py'],creationflags=CREATE_NEW_CONSOLE)

//--------------------------------------------------------------------------------------
//example 3:
from subprocess import Popen,CREATE_NEW_CONSOLE
Popen('cmd dir',creationflags=CREATE_NEW_CONSOLE,cwd='c:')
Popen(['cmd','/C','dir'],cwd='c:')

//--------------------------------------------------------------------------------------
//example 4:
from shlex import split
from subprocess import Popen,CREATE_NEW_CONSOLE
cmd_1 = "cmd /K demoICE.exe server";
cmd_2 = "cmd /K demoICE.exe client";
args_1 = split(cmd_1);
args_2 = split(cmd_2);
Popen(args_1,cwd="D:demo-devdev_nativedemoICEx64Release");
Popen(args_2,cwd="D:demo-devdev_nativedemoICEx64Release");
