如何通过批处理脚本检查进程是否正在运行 [英] How to check if a process is running via a batch script

问题描述

如何检查应用程序是否正在从批处理(以及 cmd)文件中运行?

How can I check if an application is running from a batch (well cmd) file?

如果程序已经在运行，我不需要启动另一个实例.(我无法更改应用以使其仅成为单个实例.)

I need to not launch another instance if a program is already running. (I can't change the app to make it single instance only.)

该应用程序也可以以任何用户身份运行.

Also the application could be running as any user.

推荐答案

我想到的另一种可能性，它不需要保存文件，灵感来自于 grep 是:

Another possibility I came up with, which does not require to save a file, inspired by using grep is:

tasklist /fi "ImageName eq MyApp.exe" /fo csv 2>NUL | find /I "myapp.exe">NUL
if "%ERRORLEVEL%"=="0" echo Program is running

• /fi "" 定义要查找的应用程序过滤器，在我们的例子中是 *.exe 名称
• /fo csv 定义输出格式，csv 是必需的，因为默认情况下，如果可执行文件的名称太长，则可能会被截断，因此 find<将无法匹配/code> 稍后.
• find/I 表示不区分大小写匹配，可以省略
• /fi "" defines a filter of apps to find, in our case it's the *.exe name
• /fo csv defines the output format, csv is required because by default the name of the executable may be truncated if it is too long and thus wouldn't be matched by find later.
• find /I means case-insensitive matching and may be omitted

请参阅tasklist 命令用于整个语法.

See the man page of the tasklist command for the whole syntax.
