使用wmic将参数传递给可执行文件 [英] Getting the arguments passed to a executable using wmic

问题描述

我试图获取由另一个程序启动的可执行文件的命令行参数。

I am trying to get commandline arguments of an executable which was launched by another program.

我尝试了这个答案，但是我听不懂语法：（

I tried the command mentioned in this answer, but I can't understand the syntax :(

我试图获取的命令行参数一个进程，我有PID&进程名，在这种情况下，我尝试获取ping命令的参数，该命令用于测试命令...

I am trying to get the commandline arguments of an process, I have the PID & the process name, In this case I am trying get arguments of an ping command which I am using to test the command...

在此先感谢：）

推荐答案

尝试一下：

wmic process where "name='ping.exe'" get commandline /format:list

或者如果您希望按PID查询：

Or if you prefer to query by PID:

wmic process where "processid='NNNN'" get commandline /format:list

wmic 使用查询称为WQL的语言，类似于SQL。您可以执行通配符之类的操作，例如 wmic进程，其中名称如'ping％'将获得命令行（但请确保将 %% 在批处理脚本中），更改输出样式（列表，csv甚至是html）和其他魔术。有关更多信息，请参见命令行中的 wmic /？。

wmic uses a query language called WQL, which is similar to SQL. You can do wildcard stuff like wmic process where "name like 'ping%'" get commandline (but be sure to double the %% within a batch script), vary the output style (list, csv, even html), and other magic. See wmic /? from a command line for more info.

如果要捕获任何命令到变量的输出，请使用 for / f 循环。在cmd控制台中帮助以获取更多信息。在cmd控制台中尝试以下操作：

If you want to capture the output of any command to a variable, use a for /f loop. help for in a cmd console for more info. Try this in a cmd console:

for /f "delims=" %I in ('wmic process where "name='ping.exe'" get commandline /format:list ^| find "="') do set "%I"

您会发现确实有些奇怪。该命令的输出将类似于以下内容：

You'll notice something very odd indeed. The output of that command will be similar to this:

\Users\username> set CommandLine = ping- n 60本地主机

在行的开始处打印右引号！那不是很奇怪吗？那是因为WMI查询结果是用UCS-2 LE而不是ANSI编码的。

The closing quotation mark gets printed at the beginning of the line! Isn't that weird? That's because WMI query results are encoded in UCS-2 LE, not ANSI.

我要使用的一种解决方法是使用 / format：csv 并在查询中添加一次性列。

One workaround I like to use is to use /format:csv and add a disposable column to the query.

从批处理脚本中：

for /f "tokens=2 delims=," %%I in (
    'wmic process where "name='ping.exe'" get commandline^,status /format:csv'
) do set "commandline=%%I"

...这样一来，您就不会在变量中捕获任何不可见的背信弃义。

... and that way you won't capture any invisible treachery to your variable.
