修剪 Powershell OutPut

Question

要求是修整 Output。 僅保留名稱中雙引號內引用的 output 並刪除/避免較早的行/字符

從：

$R.Output = \\GBVServer1\root\cimv2:Win32_Group.Domain="Contoso",Name="Domain Users"

$R.Output = \\GBVServer1\root\cimv2:Win32_SystemAccount.Domain="GBVServer1",Name="INTERACTIVE"

至：

$R.Output = Domain Users

$R.Output = INTERACTIVE

有人可以協助使用 powershell 開關嗎？

Answer 1

您可以使用正則表達式執行此操作，以僅捕獲這些字符串的引號之間的名稱部分：

$regex = [regex]'(?i)Name="([^,]+)"'

$string = '\\GBVServer1\root\cimv2:Win32_Group.Domain="Contoso",Name="Domain Users"'
$R.Output = $regex.Match($string).Groups[1].Value  # --> Domain Users

$string = '\\GBVServer1\root\cimv2:Win32_SystemAccount.Domain="GBVServer1",Name="INTERACTIVE"'
$R.Output = $regex.Match($string).Groups[1].Value  # --> INTERACTIVE

正則表達式詳細信息：

Name="      Match the characters “Name="” literally
(           Match the regular expression below and capture its match into backreference number 1
   [^,]     Match any character that is NOT a “,”
      +     Between one and unlimited times, as many times as possible, giving back as needed (greedy)
)
"           Match the character “"” literally

^{(?i)使匹配不區分大小寫}
