如何使用命令行和/或powershell在windows 2012服务器上以GB为单位找到所有活动驱动器卷上的可用空间。
到目前为止我试过这个命令，那失败了：

wmic logicaldisk get size,freespace,caption
Invalid GET Expression.

我也试过这个命令，但它给出的答案是字节，这是很难解释。如果我可以得到这个读取GB：

PS C:\Users\us-tdunphy> wmic diskdrive list brief /format:list

Caption=AWS PVDISK SCSI Disk Device
DeviceID=\\.\PHYSICALDRIVE1
Model=AWS PVDISK SCSI Disk Device
Partitions=1
Size=268432012800

Caption=AWS PVDISK SCSI Disk Device
DeviceID=\\.\PHYSICALDRIVE0
Model=AWS PVDISK SCSI Disk Device
Partitions=1
Size=128849011200

我还尝试了这个powershell命令，它给出了一个错误：

PS C:\Users\us-tdunphy> powershell -command "& {Get-WmiObject -Class Win32_LogicalDisk -Filter 'DriveType = 3' |select PSComputerName, Caption,@{N='Capacity_GB'; E={[math]::Round(($_.Size / 1GB), 2)}},@{N='FreeSpace_GB'; E={[math]::Round(($_.FreeSpace / 1GB), 2)}},@{N='PercentUsed'; E={[math]::Round(((($_.Size - $_.FreeSpace) / $_.Size) * 100), 2) }},@{N='PercentFree'; E={[math]::Round((($_.FreeSpace / $_.Size) * 100), 2) }}}"

试着编码你的命令，CMD不喜欢那些带管道的长字符串：

$command = 'Get-WmiObject -Class Win32_LogicalDisk | Select-Object DeviceID,VolumeName,@{N="SizeGB";E={[Math]::Round($_.Size /1gb,1)}},@{N="FreeSpaceGB";E={[Math]::Round($_.FreeSpace /1gb,1)}}'
$bytes = [System.Text.Encoding]::Unicode.GetBytes($command)
$encodedCommand = [Convert]::ToBase64String($bytes)
powershell.exe -encodedCommand $encodedCommand

您可以尝试以下方法开始工作：

GWMI Win32_LogicalDisk |
    % {
        "DeviceID:  $($_.DeviceID)"
        "FreeSpace: $($_.FreeSpace / 1GB)GB"
    }
