Hyper-向MAC地址添加冒号

Question

我有多个IP/MAC地址的VM

我使用这段代码获取多个IP/MAC地址：

$vms=Get-VM | Where { $_.State –eq ‘Running’ } | Select-Object -ExpandProperty Name 


 foreach($vm in $vms) {

    $out=Get-VMNetworkAdapter -vmname $vm | select VMName, MacAddress, IPAddresses

    $virtm=$out.VMName

    $ip=$out.IPAddresses



    if ($ip.Count -gt 1){

        foreach($i in $ip.Count) {
         if ($ip -match ':'){

         $ip = $ip | ?{$_ -notmatch ':'}

  }
}         
      $ip = $ip -join " "
      $virtm = ($virtm -split '\n')[0]
}
     else {
     $ip=$out.IPAddresses
       }

    $mac=$out.MacAddress

     if ($mac.count -gt 1) {

    $mac = $mac -join " "
        }

   foreach($m in $mac) {
     $mac=$m.Insert(2,":").Insert(5,":").Insert(8,":").Insert(11,":").Insert(14,":")

    }

     Write-Output "$virtm, $ip, $mac"

这段代码工作得很好，希望它可以将列添加到第一个MAC地址。

电流输出：

OAP80, 192.168.87.45 192.168.1.45, 00:15:5D:58:12:5E 00155D58125F

我想为特定VM的所有其他MAC地址添加列。

期望输出

OAP80, 192.168.87.45 192.168.1.45, 00:15:5D:58:12:5E 00:15:5D:58:12:5F

在将集合转换为字符串之前，我尝试添加:。

$mac=$out.MacAddress
  $mac=$mac.Insert(2,":").Insert(5,":").Insert(8,":").Insert(11,":").Insert(14,":")

但得到：

Exception calling "Insert" with "2" argument(s): "Collection was of a fixed size."
At line:35 char:6
+      $mac=$mac.Insert(2,":").Insert(5,":").Insert(8,":").Insert(11,":").Insert(1 ...

Answer 1

简而言之，您可以这样做，在Mac地址中放置冒号，并将它们合并为单个字符串，并以空格作为分隔符：

$mac = ($out.MacAddress | ForEach-Object {
    $_.Insert(2,":").Insert(5,":").Insert(8,":").Insert(11,":").Insert(14,":")
}) -join ' '

Write-Output "$virtm, $ip, $mac"

Answer 2

这个怎么样？"$&“指的是整个比赛。行尾也有负值，所以冒号不会放在末尾。

$mac = echo 00155D58125F 00155D58125G 00155D58125H
$mac = $mac -replace '..(?!$)','$&:' 
$mac 

00:15:5D:58:12:5F
00:15:5D:58:12:5G
00:15:5D:58:12:5H

Answer 3

您不需要foreach用于$mac，只需使用后(如果mac格式为xx-xx-xx)

if ($mac.count -gt 1) {

    $mac = $mac -join " "
        }
$mac.Replace('-',':')

您可以这样做(如果mac格式为xxxxxxxxxxxx)：$mac=$out.MacAddress|foreach{($_.Insert(2,":").Insert(5,":").Insert(8,":").Insert(11,":").Insert(14,":"))-join " "}

并可删除以下内容：

if ($mac.count -gt 1) { $mac = $mac -join " " } foreach($m in $mac) { $mac=$m.Insert(2,":").Insert(5,":").Insert(8,":").Insert(11,":").Insert(14,":") }
