I'm writing a PowerShell script and I want to get the Number only from Get-Disk.

Something like this.  

$DiskNum=Get-Disk|Where-ObjectFilterScript{$_.Bustype -Eq"USB"} |Select-ObjectNumber

However I want $DiskNum to have just the disk number.  At the moment has a table that looks like this Number

                                                                                                                                                      ---------

                                                                                                                                                             1

All and any comments greatly appreciated.

Use 'Select-Object -ExpandProperty Number' on the end.

So you're aware, you can also do this with dotted-notation in PowerShell 3.0 and greater, which you must be using if you're using the Get-Disk cmdlet.

$DiskNum = (Get-Disk | Where-Object FilterScript {$_.Bustype -Eq "USB"}).Number

Alright.  Both yours and Tommy's solution work just fine.   Although on first try your solution seems a bit faster.  Further testing will be done.

Thanks guys.
