In a previous tip you learned how you can forward function parameters to cmdlets. But what if you just want to forward some of the parameters? Here is a sample:
function Get-BIOS($ComputerName, $Credential, [switch]$Verbose) { $a = $global:psboundparameters $psboundparameters.remove('verbose') | Out-Null $bios = Get-WmiObject Win32_BIOS @psboundparameters if ($verbose) { $bios | Select-Object * } else { $bios } } Get-BIOS -Verbose Get-BIOS -ComputerName storage1 -Verbose
The function supports three parameters, but only two should be forwarded to Get-WmiObject. The remaining parameter -Verbose is used internally by the function. To prevent -Verbose from being forwarded to Get-WmiObject, you can remove that key from $psboundparameters before you splat it to Get-WmiObject.
