我正在编写一个批处理脚本，我必须将当前连接的USB设备连接到Windows。我用了这个命令
C:\Users\Virima>wmic path win32_usbcontrollerdevice get Dependent /format:list
其输出

我想从输出中仅提取DeviceID并在注册表搜索中使用。 我打算做
`REG QUERY HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\$DeviceID`
任何帮助将不胜感激。
答案 0 :(得分：0)
for /f tokens^=2^ delims^=^" %A in ('wmic path win32_usbcontrollerdevice get Dependent') do @REG QUERY "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\%A"
WMIC.exe命令可以获取所需的内容。
wmic path win32_usbcontrollerdevice get Dependent
这里的真正挑战是，当FOR参数已经用dbl引号引起来时，如何告诉delims来分隔dbl引号。
FOR期望传递给它的第二个参数包含任何“ delims”，“ tokens”和“ skip”指令，并用双引号引起来，从而使所有三个参数成为单个参数。通过转义集合中的每个空格和特殊字符，我们可以创建不带dbl引号的相同效果-转义字符是插入符号（{^}字符）。有了转义符，并告诉for在dbl-quotes处剪切/定界，我们就可以对WMIC.exe输出进行剪切了。
for /f tokens^=2^ delims^=^" %A in ('wmic path win32_usbcontrollerdevice get Dependent') do @echo %A
现在只需混入“ HKLM”信息以及您提到的REG QUERY命令，我们就可以正常运行呼叫。
for /f tokens^=2^ delims^=^" %A in ('wmic path win32_usbcontrollerdevice get Dependent') do @REG QUERY "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\%A"
