wmi - 文件路径中的 wmic 空间，导致 No Instance(s) Available

Question

我正在使用 wmic 使用文件的完整路径获取有关服务的信息。

wmic service where PathName="C:\\Windows\\system32\\CxAudMsg64.exe"

哪个工作正常。但是，当我使用带有空格的路径时，如下所示：

wmic service where PathName="C:\\Program Files (x86)\\Common Files\\Adobe\\ARM\\1.0\\armsvc.exe"

它告诉我：“没有可用的实例。” 这是不正确的，因为路径正确并且服务存在。我需要逃离路径中的空间还是什么？

我的错。

wmic service

wmic 服务显示 PathName 值有时会与 qoutes 一起列出，有时则不会。你必须检查两者。

wmic service where PathName='"C:\\Program Files (x86)\\Common Files\\Adobe\\ARM\\1.0\\armsvc.exe"'

和

wmic service where PathName='C:\\Program Files (x86)\\Common Files\\Adobe\\ARM\\1.0\\armsvc.exe'

TL;DR -

wmic service where "pathname='\"C:\\ProgramData\\Microsoft\\Windows Defender\\platform\\4.18.1902.2-0\\NisSrv.exe\"' AND ServiceSpecificExitCode=0" get name

#OR....

wmic service where (pathname="\"C:\\ProgramData\\Microsoft\\Windows Defender\\platform\\4.18.1902.2-0\\NisSrv.exe\"" AND ServiceSpecificExitCode=0) get name

While the other answer works for single-criterion questions, it'll error out for a compound query. I recommend using either the "Quote Before Equals" syntax or the "Paren Around Where" syntax. Here are some examples

Single-Where + Quote After Equals
