List all Server Features/Roles in Powershell

Question

So I have the following code to output all features and roles installed:

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]
}

However, the output is:

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

How can I get rid of the @ and {}'s ?

Answer 1

Use Select -ExpandProperty Name instead of Select -Property Name

Alternatively and also, I recommend using Foreach-Object instead of a C-style for loop.

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

Or

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

Answer 2

How about a nice one liner?

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