在powershell

Question

我正在运行以下powershell命令：

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

结果是

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

我需要一个包含计算机名称的附加列 我怎么能这样做？

Answer 1

您可以使用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}}

此外，ft（Format-Table的别名）提供了格式化字符串 - 您希望避免将格式化输出存储在变量中 - 等到您想要在管道格式化cmdlet之前显示数据< / p>

Answer 2

尝试

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

PSComputerName也可以代替__SERVER
