列出Powershell中的所有服务器功能/角色

Question

所以我有以下代码输出安装的所有功能和角色:

Import-Module ServerManager
$Arr = Get-WindowsFeature | Where-Object {$_.Installed -match “True”} | Select-Object -Property Name
$loopCount = $Arr.Count
For($i=0; $i -le $loopCount; $i++) {
    Write-Host $Arr[$i]
}

但是,输出是:

@{Name=Backup-Features}
@{Name=Backup}
@{Name=Backup-Tools}

我怎么能摆脱@和{}？

Answer 1

用Select -ExpandProperty Name而不是Select -Property Name

或者,我建议使用Foreach-Object而不是C风格的循环.

Import-Module ServerManager
Get-WindowsFeature | 
    Where-Object {$_.Installed -match “True”} | 
    Select-Object -ExpandProperty Name |
    Write-Host

要么

Import-Module ServerManager
Get-WindowsFeature | 
    Where-Object {$_.Installed -match “True”} | 
    ForEach-Object {
        $_.Name | Write-Host
    }

Answer 2

一个漂亮的衬垫怎么样？

Get-WindowsFeature | ? {$_.Installed -match “True”} | Select -exp Name
