提取ClusterName RegularExpressions [英] Extracting ClusterName RegularExpressions

问题描述

我有一个正则表达式，它将给出计算机名称，群集名称& OSinfo

I have a regular expression which will give the computername, cluster name & OSinfo

Get-QADComputer | ？ {$ .osname -match 2008-和$ .computername -match hv} |
选择@ {Name = ComputerName; Expression = {$ _。computername.replace（ $，）}}
， @ {Name = ClusterName; Expression = {$ .computername.replace（ $，）; $ .computername.replace（ n [0-9] [0-9] ，）}}，@ {Name = OperatingSystem; Expression = {$ _。osname}}

Get-QADComputer | ? {$.osname -match "2008" -and $.computername -match "hv"} | Select @{Name="ComputerName";Expression={$_.computername.replace("$","")}} ,@{Name="ClusterName";Expression={$.computername.replace("$","");$.computername.replace("n[0-9][0-9]","")}},@{Name="OperatingSystem";Expression={$_.osname}}

现在我面临的问题是提取集群名称，例如，如果计算机名称输出为ADFCGS1N01 $，则
，我希望群集名称看起来像ADFCGSN1，我想删除N之后的所有字符以获得群集名称，

Now the problem im facing is in extracting the clustername, for example if output of computer name is ADFCGS1N01$, i wanted the cluster name to look like ADFCGSN1, i wanted to remove all the characters after N to get cluster name,

有人可以帮我吗

推荐答案

这是否给您正确的价值？

Does this gives you the correct value?

Get-QADComputer -OSName *2008* -Name *hv* | Select -ExpandProperty Name

根据您的评论，删除名称末尾的N + 2位数字，包括美元（如果存在）：

Per your comment, remove the N+2 digits from the end of name, including the dollar (if exists):

Get-QADComputer -OSName *2008* -Name *hv* | Foreach-Object {$_.Name -replace 'N\d{2}\$?$'}
