Improved Function: Get-ComputerDetail

PowerShell for Admins

Fellow coders, I received some great feedback from our honorary scripting guru’s Mike F. Robbins and Richard Siddaway about my little function (thanks guys! I’ll buy you a drink when we meet! 😉 ).

With their feedback I managed to improve my simple function. And that’s so great about being part of a community; people are always willing to help.

#requires -Version 2
Function Get-ComputerDetail
{
    [cmdletbinding()]
    param (
        [ValidateNotNullOrEmpty()]
        [string[]]$ComputerName = $env:COMPUTERNAME
    )
    foreach ($node in $ComputerName)
    {
        try
        {
            $computerSystem		= Get-WmiObject -Class 'Win32_ComputerSystem' -ComputerName $node -ErrorAction Stop
            $computerBios		= Get-WmiObject -Class 'Win32_Bios' -ComputerName $node -ErrorAction Stop
            [pscustomobject][ordered]@{
                Name         	= $computerSystem.Name
                Manufacturer 	= $computerSystem.Manufacturer
                Model        	= $computerSystem.Model
                Serial       	= $computerBios.SerialNumber
            } # End of custom object
        } # End of try
        catch
        {
            Write-Error -Message "The command failed for computer $node. Message: $_.Exception.Message"
            break
        }# End of Catch
    }# End of foreach
}# End of function

    One more suggested mod. This will process everything in the list, and then print out all the errors at the end of the run.

    Function Get-ComputerDetails
{
    [cmdletbinding()]
    Param([string[]]$Computer)
    $msg = ""
    foreach ($node in $Computer)
    {
        try
        {
            $sys = Get-WmiObject -Class Win32_ComputerSystem -ComputerName $node -ErrorAction Stop
            $bios = Get-WmiObject -Class Win32_Bios -ComputerName $node -ErrorAction Stop
            [pscustomobject][ordered]@{
                Name         = $sys.Name
                Manufacturer = $sys.Manufacturer
                Model        = $sys.Model
                Serial       = $bios.SerialNumber
            }
        }
        catch
        {
            $msg += "The command failed for computer $node. Message: $_.Exception.Messagern"
            continue
        }
    }
    if ("" -ne $msg) { Write-Error -Message $msg }
}
