windows - 通过命令提示符只获取以太网 MAC 地址

Question

我使用 'ipconfig/all' 或 'getmac/v' 来获取所有 NIC 物理地址。

但问题是，一般一台电脑有多个网卡。此外，还有一些虚拟 MAC 地址，例如 Microsoft 虚拟 wifi 热点网卡，仅在 wifi 热点打开时显示。

那么，如何通过cmd只收集以太网对应的地址呢？

Answer 1

我建议你使用powershell，因为它比cmd强大

Get-CimInstance win32_networkadapterconfiguration | select description, macaddress | where {$_.MACAddress -ne $n
ull }

输出 :

description                                                 macaddress
-----------                                                 ----------
RAS Async Adapter                                           20:41:53:59:4E:FF
Realtek PCIe GBE Family Controller                          18:03:73:65:64:AB
VMware Virtual Ethernet Adapter for VMnet1                  00:50:56:C0:00:01
VMware Virtual Ethernet Adapter for VMnet8                  00:50:56:C0:00:08

powershell 中的该命令选择设备的所有 macaddress 启用包含 vmware 的机器，但我们可以做更多的过滤，例如

Get-CimInstance win32_networkadapterconfiguration | select description, macaddress | where {$_.MACAddress -ne $n
ull }  | where {$_.Description -match "Realtek" }

输出 :

description                                                 macaddress
-----------                                                 ----------
Realtek PCIe GBE Family Controller                          18:03:73:65:64:AB

但是如果你只是在 cmd 中运行，你应该像这样在 powershell 中编码这个命令

$script={ Get-CimInstance win32_networkadapterconfiguration | select description, macaddress | where {$_.MACAddr
ess -ne $null }  | where {$_.Description -match "Realtek" } }

[System.Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes( $script))

输出 用于 cmd 的编码命令

在 cmd 中，我使用它并获得 mac
