@BanterBoy: - Explain what the script does and why it is useful.
@GitHub Copilot - This PowerShell script is called Get-ServerInstalledFeatures.ps1 and it retrieves the installed features of a Windows server. The script takes a list of computer names as input and uses the Invoke-Command cmdlet to execute the Get-WindowsFeature cmdlet on each computer. The results are then processed and output as a list of PowerShell objects.
The script uses the PROCESS block to iterate over each computer name in the input list. Inside the loop, the Get-WindowsFeature cmdlet is executed on the remote computer using the Invoke-Command cmdlet. The results are stored in the $instances variable.
The script then iterates over each item in the $instances variable using a foreach loop. Inside the loop, the script creates a hash table called $properties that contains the properties of the current item. If an error occurs while creating the hash table, the script writes an error message to the console using the Write-Error cmdlet.
Finally, the script creates a new PowerShell object using the New-Object cmdlet and the properties from the $properties hash table. The object is then output to the console using the Write-Output cmdlet.
Overall, this script is a useful tool for retrieving information about the installed features of Windows servers. However, it could be improved by adding more error handling and by optimizing the code for performance. For example, the script could use the -AsJob parameter of the Invoke-Command cmdlet to execute the Get-WindowsFeature cmdlet in parallel on multiple computers, which would improve the performance of the script. Additionally, the script could use the Try/Catch/Finally statement to handle errors more gracefully and provide more detailed error messages to the user.
@BanterBoy: - Can you provide examples for using the script
@GitHub Copilot - Sure! Here are a few examples of how you can use the Get-ServerInstalledFeatures script:
-
To retrieve the installed features of a single server, run the following command:
Get-ServerInstalledFeatures -ComputerName "Server01"This will retrieve the installed features of the server named “Server01”.
-
To retrieve the installed features of multiple servers, run the following command:
Get-ServerInstalledFeatures -ComputerName "Server01", "Server02", "Server03"This will retrieve the installed features of the servers named “Server01”, “Server02”, and “Server03”.
-
To retrieve the installed features of all servers in an Active Directory domain, run the following command:
Get-ADComputer -Filter {OperatingSystem -Like "*Windows Server*"} | Select-Object -ExpandProperty Name | Get-ServerInstalledFeaturesThis will retrieve the installed features of all servers in the Active Directory domain that have a Windows Server operating system.
-
To save the results to a CSV file, run the following command:
Get-ServerInstalledFeatures -ComputerName "Server01", "Server02", "Server03" | Export-Csv -Path "C:\Features.csv" -NoTypeInformationThis will retrieve the installed features of the servers named “Server01”, “Server02”, and “Server03”, and save the results to a CSV file named “Features.csv” in the C:\ directory.
