Question

如何使用命令行和/或powershell在Windows 2012服务器上找到GB中所有活动驱动器卷上的可用空间。

到目前为止，我尝试了这个命令，但失败了：

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

还尝试了这个命令，但它给出了难以解释的字节答案。如果我能用GB读出来，那就太棒了：

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

我也试过这个给出错误的powershell命令：

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) }}}"

Answer 1

你可以尝试这个开始工作：

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

Answer 2

尝试对命令进行编码，CMD不喜欢那些带有管道的长字符串：

$command = 'Get-WmiObject -Class Win32_LogicalDisk | Select-Object DeviceID,VolumeName,@{N="SizeGB";E={[Math]::Round($_.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
