START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
         [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
         [/NODE] [/AFFINITY] [/WAIT] [/B]
         [command/program] [parameters]

"title"	标题显示在窗口的标题栏中。
path	起始目录。
/B	启动应用程序而不创建新窗口。该应用程序忽略了^ C处理。除非应用程序启用^ C处理，否则^ Break是中断应用程序的唯一方法。
/I	新环境将是传递给cmd.exe的原始环境，而不是当前环境。
/MIN	启动窗口最小化。
/MAX	启动窗口最大化。
/SEPARATE	在IDLE优先级类中启动应用程序。
/SHARED	在共享内存空间中启动16位Windows程序。
/LOW	在IDLE优先级类中启动应用程序。
/NORMAL	在NORMAL优先级类中启动应用程序。
/HIGH	在HIGH优先级类中启动应用程序。
/REALTIME	在REALTIME优先级类中启动应用程序。
/ABOVENORMAL	在ABOVENORMAL优先级类中启动应用程序。
/BELOWNORMAL	在BELOWNORMAL优先级类中启动应用程序。
/NODE	将首选的NUMA（非统一内存体系结构）节点指定为十进制整数。
/AFFINITY	将处理器亲和力掩码指定为十六进制数。该过程仅限于在这些处理器上运行 AFFINITY和/ NODE结合使用时，亲和力掩码的解释会有所不同。指定亲和力掩码，就好像NUMA节点的处理器掩码右移以从零位开始。该过程仅限于在指定的亲和力掩码和NUMA节点之间共有的那些处理器上运行。如果没有共同的处理器，则该进程仅限于在指定的NUMA节点上运行。
/WAIT	启动应用程序并等待其终止。
command/program	如果它是内部cmd命令或批处理文件，则使用/ K开关将命令处理器运行到cmd.exe。这意味着该窗口将在运行命令后保留。如果它不是内部cmd命令或批处理文件，则它是一个程序，可以作为窗口应用程序或控制台应用程序运行。
parameters	这些是传递给命令/程序的参数。

Specifying /NODE NODE允许以利用NUMA系统上的内存局部性的方式来创建进程。例如，可以创建两个通过共享内存进行大量通信的进程，以共享相同的首选NUMA节点，以最大程度地减少内存延迟。它们在可能的情况下从同一NUMA节点分配内存，并且可以在指定节点之外的处理器上自由运行。

开始/ NODE 1 / AFFINITY 0x3 application1.exe
开始/ NODE 1 / AFFINITY 0xc application2.exe

如果启用了命令扩展，则通过命令行或START命令进行的外部命令调用将发生如下变化：

通过将文件名作为命令键入，可以通过非可执行文件的文件关联来调用非可执行文件。（例如WORD.DOC将启动与.DOC文件扩展名关联的应用程序）。有关如何从命令脚本中创建这些关联的信息，请参见ASSOC和FTYPE命令。

当执行的应用程序是32位GUI应用程序时，CMD.EXE在返回命令提示符之前不会等待该应用程序终止。如果在命令脚本中执行，则不会发生此新行为。

当执行命令行的第一个标记是没有扩展名或路径限定符的字符串“ CMD”时，则将“ CMD”替换为COMSPEC变量的值。此更改可防止从当前目录中拾取CMD.EXE 。

当执行命令行的第一个标记不包含扩展名时，CMD.EXE使用PATHEXT环境变量的值来确定扩展名。PATHEXT变量的默认值为：

.COM;.EXE;.BAT;.CMD

注意语法与PATH变量相同，用分号分隔不同的元素。

搜索可执行文件时，如果任何扩展名都不匹配，则查看该名称是否与目录名称匹配。如果是这样，START命令将在该路径上启动资源管理器。如果从命令行完成，则相当于对该路径执行CD / D。

Windows Vista and later syntax

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
         [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
         [/NODE] [/AFFINITY] [/WAIT] [/B]
         [command/program] [parameters]

"title"	Title to display in the window's title bar.
path	Starting directory.
/B	Start an application without creating a new window. The application has ^C handling ignored. Unless the application enables ^C processing, ^Break is the only way to interrupt the application.
/I	The new environment will be the original environment passed to the cmd.exe and not the current environment.
/MIN	Start window minimized.
/MAX	Start window maximized.
/SEPARATE	Start 16-bit Windows program in separate memory space.
/SHARED	Start 16-bit Windows program in shared memory space.
/LOW	Start application in the IDLE priority class.
/NORMAL	Start application in the NORMAL priority class.
/HIGH	Start application in the HIGH priority class.
/REALTIME	Start application in the REALTIME priority class.
/ABOVENORMAL	Start application in the ABOVENORMAL priority class.
/BELOWNORMAL	Start application in the BELOWNORMAL priority class.
/NODE	Specifies the preferred NUMA (Non-Uniform Memory Architecture) node as a decimal integer.
/AFFINITY	Specifies the processor affinity mask as a hexadecimal number. The process is restricted to running on these processors. The affinity mask is interpreted differently when /AFFINITY and /NODE are combined. Specify the affinity mask as if the NUMA node's processor mask is right shifted to begin at bit zero. The process is restricted to running on those processors in common between the specified affinity mask and the NUMA node. If no processors are in common, the process is restricted to running on the specified NUMA node.
/WAIT	Start the application and wait for it to terminate.
command/program	If it is an internal cmd command or a batch file, then the command processor is run with the /K switch to cmd.exe. Which means the window will remain after the command is run. If it is not an internal cmd command or batch file, then it is a program and runs as either a windowed application or a console application.
parameters	These are the parameters passed to the command/program.

Specifying /NODE allows processes to be created in a way that leverages memory locality on NUMA systems. For example, two processes that communicate with each other heavily through shared memory can be created to share the same preferred NUMA node to minimize memory latencies. They allocate memory from the same NUMA node when possible, and they are free to run on processors outside the specified node.

start /NODE 1 /AFFINITY 0x3 application1.exe
start /NODE 1 /AFFINITY 0xc application2.exe

If Command Extensions are enabled, external command invocation through the command line or the START command changes as follows:

non-executable files may be invoked through their file association by typing the name of the file as a command. (e.g., WORD.DOC would launch the application associated with the .DOC file extension). See the ASSOC and FTYPE commands for how to create these associations from within a command script.

When executing an application that is a 32-bit GUI application, CMD.EXE does not wait for the application to terminate before returning to the command prompt. This new behavior does NOT occur if executing in a command script.

When executing a command line whose first token is the string "CMD" without an extension or path qualifier, then "CMD" is replaced with the value of the COMSPEC variable. This change prevents picking up CMD.EXE from the current directory.

When executing a command line whose first token does NOT contain an extension, CMD.EXE uses the value of the PATHEXT environment variable to determine the extension. The default value for the PATHEXT variable is:

.COM;.EXE;.BAT;.CMD

Notice the syntax is the same as the PATH variable, with semicolons separating the different elements.

When searching for an executable, if there is no match on any extension, then looks to see if the name matches a directory name. If it does, the START command launches the Explorer on that path. If done from the command line, it is the equivalent to doing a CD /D to that path.

start notepad myfile.txt

使用文件myfile.txt 启动记事本的新实例。

start /MAX notepad

在屏幕最大化的情况下启动记事本窗口。

start /MIN mybatch.bat

上面的示例将在最小化的窗口中启动批处理文件mybatch.bat 。

start c:\music\"my song.mp3"

如果文件或文件夹中有空格，则必须用引号将其引起来。在上面的示例中，我们正在启动MP3歌曲文件“ my song.mp3”。如果没有周围的引号的文件名有空间，你会得到一个Windows无法找到文件错误。

start https://www.uc23.net/

从命令行在默认浏览器中打开uc23网页。

start notepad myfile.txt

Start a new instance of Notepad with the file myfile.txt.

start /MAX notepad

Start the notepad window with the screen maximized.

start /MIN mybatch.bat

The above example would start the batch file mybatch.bat in a minimized window.

start c:\music\"my song.mp3"

If the file or folder has a space in it, you must surround it with quotes. In the above example, we're starting the MP3 song file "my song.mp3". Without the quotes surrounding the file name with a space, you would get a Windows cannot find the file error.

start https://www.uc23.net/

Open the Computer Hope web page in your default browser from the command line.
