在Powershell中显示计算机名称和可用磁盘空间

Question

I'm running the following powershell command :

 $cmd = Get-WmiObject -ComputerName Drex -Class Win32_volume |  Where {($_.DriveLetter) -and ($_.FreeSpace)}| ft -auto DriveLetter,FreeSpace 
 $cmd

It gives as result

DriveLetter    FreeSpace
 -----------    ---------
 D:           39295995904
 C:          297391972352

I need to have an additional column that contains computer name
How can i do that ?

Answer 1

You can use a calculated property :

$ComputerName = 'Drex'
$Disks = Get-WmiObject -ComputerName $ComputerName -Class Win32_volume |  Where {($_.DriveLetter) -and ($_.FreeSpace)}
$Disks | Select-Object DriveLetter,FreeSpace,@{Label="Computername";Expression={$ComputerName}}

Also, ft (an alias for Format-Table ) provides a formatted string - you want to avoid storing formatted output in variables - wait until you want to display your data before you pipe to formatting cmdlets

Answer 2

Try

$cmd = Get-WmiObject -ComputerName Drex -Class Win32_volume |  Where {($_.DriveLetter) -and ($_.FreeSpace)}| ft -auto DriveLetter,FreeSpace, __SERVER

PSComputerName also works instead of __SERVER
