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.

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.Message[crayon-5f936e2d9a5b6973146283 inline="true" ]rn”
continue
}
}
if (“” -ne $msg) { Write-Error -Message $msg }
}
[/crayon]
… not to mention, completely flatten the code. 🙂
Nice one .. Thanks for sharing
