在本章中，我们将讨论批处理脚本中涉及的各种过程。

查看正在运行的进程列表

在批处理脚本中，TASKLIST命令可用于获取系统中当前正在运行的进程的列表。

句法

TASKLIST [/S system [/U username [/P [password]]]] [/M [module] | /SVC | /V] [/FI filter]
[/FO format] [/NH]

以下是可以显示给TASKLIST命令的选项的描述。

S.No.	Options & Description
1.	/S system Specifies the remote system to connect to
2.	/U [domain\]user Specifies the user context under which the command should execute.
3.	/P [password] Specifies the password for the given user context. Prompts for input if omitted.
4.	/M [module] Lists all tasks currently using the given exe/dll name. If the module name is not specified all loaded modules are displayed.
5.	/SVC Displays services hosted in each process.
6.	/V Displays verbose task information.
7.	/FI filter Displays a set of tasks that match a given criteria specified by the filter.
8.	/FO format Specifies the output format. Valid values: “TABLE”, “LIST”, “CSV”.
9.	/NH Specifies that the “Column Header” should not show in the output. Valid only for “TABLE” and “CSV” formats.

例子

tasklist > process.txt

上面的命令获取任务列表显示的输出，并将其保存到process.txt文件中。

tasklist /fi "memusage gt 40000"

杀死一个特定的过程

允许运行Microsoft Windows XP Professional，Windows 2003或更高版本的用户通过进程ID(PID)或映像名称从Windows命令行中终止任务。用于此目的的命令是TASKILL命令。

句法

TASKKILL [/S system [/U username [/P [password]]]] { [/FI filter] 
[/PID processid | /IM imagename] } [/T] [/F]

以下是可以显示给TASKKILL命令的选项的说明。

S.No.	Options & Description
1.	/S system Specifies the remote system to connect to
2.	/U [domain\]user Specifies the user context under which the command should execute.
3.	/P [password] Specifies the password for the given user context. Prompts for input if omitted.
4.	/FI FilterName Applies a filter to select a set of tasks. Allows “” to be used. ex. imagename eq acme See below filters for additional information and examples.
5.	/PID processID Specifies the PID of the process to be terminated. Use TaskList to get the PID.
6.	/IM ImageName Specifies the image name of the process to be terminated. Wildcard ‘*’ can be used to specify all tasks or image names.
7.	/T Terminates the specified process and any child processes which were started by it.
8.	/F Specifies to forcefully terminate the process(es).

例子

taskkill /f /im notepad.exe

上面的命令将杀死打开的记事本任务(如果已打开)。

taskill /pid 9214

上面的命令将杀死一个进程为9214的进程。

开始新流程

DOS脚本还可以完全启动一个新进程。这可以通过使用START命令来实现。

句法

START "title" [/D path] [options] "command" [parameters]

其中

title -CMD窗口标题栏的文本(必填。)
路径-起始目录。
命令-要运行的命令，批处理文件或可执行程序。
参数-传递给命令的参数。

以下是可以显示给START命令的选项的说明。

S.No.	Options & Description
1.	/MIN Start window Minimized
2.	/MAX Start window maximized.
3.	/LOW Use IDLE priority class.
4.	/NORMAL Use NORMAL priority class.
5.	/ABOVENORMAL Use ABOVENORMAL priority class.
6.	/BELOWNORMAL Use BELOWNORMAL priority class.
7.	/HIGH Use HIGH priority class.
8.	/REALTIME Use REALTIME priority class.

例子

START "Test Batch Script" /Min test.bat

上面的命令将在新窗口中运行批处理脚本test.bat。窗口将以最小化模式启动，并且标题为“ Test Batch Script”。

START "" "C:\Program Files\Microsoft Office\Winword.exe" "D:\test\TESTA.txt"

上面的命令实际上将在另一个进程中运行Microsoft Word，然后在MS Word中打开文件TESTA.txt。
