Powershell检查远程电脑上的存储

你好，我正在构建一个菜单来运行每个所选选项的脚本，我想要的一个选项是检查远程电脑的存储，但通过研究，我已经破坏了脚本，希望能够从拥有超过一个月使用 PS 经验的人那里获得帮助。

Invoke-Command $Computer = Read-Host Please Enter Host name  -ScriptBlock{Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" | Select SystemName, DeviceID, @{n='Size(GB)';e={$_.size / 1gb -as [int]}},@{n='Free(GB)';e={$_.Freespace / 1gb -as [int]}}} > C:\DiskInfo_output.txt

Hello I am building a menu to run scripts per option selected and an option I want is to check storage of a remote pc but from researching I have broken the script and hopefully can get assistance from someone that has more than my month experience using PS.

Invoke-Command $Computer = Read-Host Please Enter Host name  -ScriptBlock{Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" | Select SystemName, DeviceID, @{n='Size(GB)';e={$_.size / 1gb -as [int]}},@{n='Free(GB)';e={$_.Freespace / 1gb -as [int]}}} > C:\DiskInfo_output.txt

您需要将 $Computer = Read-Host ... 语句移出 Invoke-Command 语句：

# Ask for computer name
$Computer = Read-Host "Please Enter Host name"

# Invoke command on remote computer
Invoke-Command -ComputerName $Computer -ScriptBlock {
    Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" | Select SystemName, DeviceID, @{n='Size(GB)';e={$_.size / 1gb -as [int]}},@{n='Free(GB)';e={$_.Freespace / 1gb -as [int]}}
} > C:\DiskInfo_output.txt

You need to move the $Computer = Read-Host ... statement out of the Invoke-Command statement:

# Ask for computer name
$Computer = Read-Host "Please Enter Host name"

# Invoke command on remote computer
Invoke-Command -ComputerName $Computer -ScriptBlock {
    Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" | Select SystemName, DeviceID, @{n='Size(GB)';e={$_.size / 1gb -as [int]}},@{n='Free(GB)';e={$_.Freespace / 1gb -as [int]}}
} > C:\DiskInfo_output.txt

您不需要使用 Invoke-Command，因为 WMI cmdlet 接受 -ComputerName 值：

$ComputerName = Read-Host -Prompt "Please Enter Host name"
Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" -ComputerName $ComputerName | 
    Select-Object -Property SystemName, DeviceID, @{
        Name ='Size(GB)';
        Expression = {
            $_.size / 1gb -as [int]
        }
    }, @{
        Name ='Free(GB)';
        Expression = {
            $_.Freespace / 1gb -as [int]
        }
    }

或者，您可以首先使用分组提示输入计算机名称运算符（Santiago 在评论中指出）：

Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" -ComputerName (Read-Host -Prompt "Please Enter Host name")

子表达式也是如此运算符，它只是告诉 PowerShell 首先请求它 - 而不需要详细说明。

旁注：

Get-WMIObject 等 WMI Cmdlet 已弃用，并已被较新的 CIM Cmdlet。

在 v3 中引入，它使用 DCOM 之外的单独远程协议。
- 也可以明确地使用 DCOM，但默认情况下不行。
强调替换，因为从 PowerShell Core 开始，它们不再是 PowerShell 部署的一部分。
如果我可以补充一下，大多数 cmdlet 翻译起来相当容易：
- Get-WmiObject -Class Win32_ologicalDisk -Filter "DeviceID='C:'"
- Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DeviceID='C:'"

You don't need to use Invoke-Command seeing as the WMI cmdlets accept a -ComputerName value:

$ComputerName = Read-Host -Prompt "Please Enter Host name"
Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" -ComputerName $ComputerName | 
    Select-Object -Property SystemName, DeviceID, @{
        Name ='Size(GB)';
        Expression = {
            $_.size / 1gb -as [int]
        }
    }, @{
        Name ='Free(GB)';
        Expression = {
            $_.Freespace / 1gb -as [int]
        }
    }

Alternatively, you can have the Computer Name input be prompted first using the grouping operator (as Santiago points out in the comments):

Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'" -ComputerName (Read-Host -Prompt "Please Enter Host name")

Same goes for the subexpression operator which just tells PowerShell to ask for it first - without going into more detail.

Side Note:

The WMI Cmdlets such as Get-WMIObject are deprecated and have been replaced by the newer CIM Cmdlets.

Introduced in v3, it uses a separate remoting protocol other than DCOM.
- This can be explicitly made to use DCOM as well, but not by default.
Emphasis on replaced as they are no longer part of PowerShell's deployment as of PowerShell Core.
Most cmdlets translate fairly easy if I may add:
- Get-WmiObject -Class Win32_logicalDisk -Filter "DeviceID='C:'"
- Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DeviceID='C:'"
