如何使用wmic命令仅从此输出获取设备ID

Question

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。我用过这个命令

C:\Users\Virima>wmic path win32_usbcontrollerdevice get Dependent /format:list

它的输出是

Dependent="\\VIRIMA-009\root\cimv2:Win32_PnPEntity.DeviceID="USB\ROOT_HUB20\4&2851D18A&0""
Dependent="\\VIRIMA-009\root\cimv2:Win32_PnPEntity.DeviceID="USB\VID_8087&PID_0020\5&15BBD570&0&1""

我想从输出中仅提取设备ID并在注册表搜索中使用。我打算这样做

`REG QUERY HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\$DeviceID`

任何帮助将不胜感激。

Answer 1

TL; DR：

for /f tokens^=2^ delims^=^" %A in ('wmic path win32_usbcontrollerdevice get Dependent') do @REG QUERY "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\%A"

细节：

WMIC.exe命令可以得到你想要的。

wmic path win32_usbcontrollerdevice get Dependent

这里真正的挑战是当FOR参数已经用dbl-quotes封装时，如何告诉delims分隔dbl-quote字符。

FOR期望传递给它的第二个参数包含任何'delims'，'tokens'和'skip'指令，用双引号括起来，有效地使所有三个参数成为一个参数。通过转义集合中的每个空格和特殊字符，我们可以在没有dbl-quotes的情况下创建相同的效果 - 转义字符是插入符号（{^}字符）。随着逃生到位，并告诉for切断/分隔dbl-quotes的线，我们准备砍掉WMIC.exe输出。

for /f tokens^=2^ delims^=^" %A in ('wmic path win32_usbcontrollerdevice get Dependent') do @echo %A

现在只需混合'HKLM'信息，以及你提到的REG QUERY命令，我们就可以完成一个功能齐全的电话。

for /f tokens^=2^ delims^=^" %A in ('wmic path win32_usbcontrollerdevice get Dependent') do @REG QUERY "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\%A"
