为什么您的RAM总是为零

Question

我对Powershell脚本还很陌生，并且一直在玩在线查找的脚本，该脚本查询域中的所有系统并以CSV格式输出一些硬件信息。脚本：

$testcomputers = Get-Content -Path 'C:\scripts\computers.txt'
$exportLocation = 'C:\scripts\pcInventory.csv'

foreach ($computer in $testcomputers) {
  if (Test-Connection -ComputerName $computer -Quiet -count 2){
    Add-Content -value $computer -path c:\scripts\livePCs.txt
  }else{
    Add-Content -value $computer -path c:\scripts\deadPCs.txt
  }
}

$computers = Get-Content -Path 'C:\scripts\livePCs.txt'

foreach ($computer in $computers) {
    $Bios =  Win32_computerSystem -Computername $Computer
    $Sysbuild = Get-WmiObGet-WmiObject win32_bios -Computername $Computer
    $Hardware = Get-WmiObjectject Win32_WmiSetting -Computername $Computer
    $OS = Get-WmiObject Win32_OperatingSystem -Computername $Computer
    $Networks = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName $Computer | Where-Object {$_.IPEnabled}
    $driveSpace = Get-WmiObject win32_volume -computername $Computer -Filter 'drivetype = 3' | 
    Select-Object PScomputerName, driveletter, label, @{LABEL='GBfreespace';EXPRESSION={'{0:N2}' -f($_.freespace/1GB)} } |
    Where-Object { $_.driveletter -match 'C:' }
    $cpu = Get-WmiObject Win32_Processor  -computername $computer
    $username = Get-ChildItem "\\$computer\c$\Users" | Sort-Object LastWriteTime -Descending | Select-Object Name, LastWriteTime -first 1
    $totalMemory = [math]::round($Hardware.TotalPhysicalMemory/1024/1024/1024, 2)
    $lastBoot = $OS.ConvertToDateTime($OS.LastBootUpTime) 

    $IPAddress  = $Networks.IpAddress[0]
    $MACAddress  = $Networks.MACAddress
    $systemBios = $Bios.serialnumber

    $OutputObj  = New-Object -Type PSObject
    $OutputObj | Add-Member -MemberType NoteProperty -Name ComputerName -Value $Computer.ToUpper()
    $OutputObj | Add-Member -MemberType NoteProperty -Name Manufacturer -Value $Hardware.Manufacturer
    $OutputObj | Add-Member -MemberType NoteProperty -Name Model -Value $Hardware.Model
    $OutputObj | Add-Member -MemberType NoteProperty -Name Processor_Type -Value $cpu.Name
    $OutputObj | Add-Member -MemberType NoteProperty -Name System_Type -Value $Hardware.SystemType
    $OutputObj | Add-Member -MemberType NoteProperty -Name Operating_System -Value $OS.Caption
    $OutputObj | Add-Member -MemberType NoteProperty -Name Operating_System_Version -Value $OS.version
    $OutputObj | Add-Member -MemberType NoteProperty -Name Operating_System_BuildVersion -Value $SysBuild.BuildVersion
    $OutputObj | Add-Member -MemberType NoteProperty -Name Serial_Number -Value $systemBios
    $OutputObj | Add-Member -MemberType NoteProperty -Name IP_Address -Value $IPAddress
    $OutputObj | Add-Member -MemberType NoteProperty -Name MAC_Address -Value $MACAddress
    $OutputObj | Add-Member -MemberType NoteProperty -Name Last_User -Value $username.Name
    $OutputObj | Add-Member -MemberType NoteProperty -Name User_Last_Login -Value $username.LastWriteTime
    $OutputObj | Add-Member -MemberType NoteProperty -Name C:_FreeSpace_GB -Value $driveSpace.GBfreespace
    $OutputObj | Add-Member -MemberType NoteProperty -Name Total_Memory_GB -Value $totalMemory
    $OutputObj | Add-Member -MemberType NoteProperty -Name Last_ReBoot -Value $lastboot
    $OutputObj | Export-Csv $exportLocation -Append -NoTypeInformation
  }

运行脚本时，出现以下错误，但不确定如何解决。我还注意到应该输出系统RAM的行始终输出0。任何指导将不胜感激。如果有任何区别，我将在Windows 7上运行Powershell 3。

Win32_computerSystem : The term 'Win32_computerSystem' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path 
was included, verify that the path is correct and try again.



Get-WmiObGet-WmiObject : The term 'Get-WmiObGet-WmiObject' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a 
path was included, verify that the path is correct and try again.



Get-WmiObjectject : The term 'Get-WmiObjectject' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was 
included, verify that the path is correct and try again.

Answer 1

语法错误

第15行：

$Bios =  Win32_computerSystem -Computername $Computer

您忘记为Win32_ComputerSystem加上Get-WmiObject前缀。它试图作为命令运行Win32_ComputerSystem，而不是评估WMI类。要解决此问题，请将行更改为如下所示：

$Bios = Get-WmiObject Win32_ComputerSystem -ComputerName $Computer

第16行：

$Sysbuild = Get-WmiObGet-WmiObject win32_bios -Computername $Computer

没有名为Get-WmiObGet-WmiObject的cmdlet。将其更改为Get-WmiObject：

$Sysbuild = Get-WmiObject Win32_Bios -ComputerName $Computer

第17行：

$Hardware = Get-WmiObjectject Win32_WmiSetting -Computername $Computer

这是尝试呼叫Get-WmiObject时的另一种错字。纠正拼写错误，它应该可以工作：

$Hardware = Get-WmiObject Win32_WmiSetting -ComputerName $Computer

为什么您的RAM总是为零

简而言之，设置$Hardware时使用的WMI类错误。您可以从Win32_PhysicalMemory类中获取物理内存信息。将第17行替换为：

$Hardware = Get-WmiObject Win32_PhysicalMemory -ComputerName $Computer

，当您获得$ totalRam时，可以使用以下计算：

$totalRamBytes = 0
$Hardware.Capacity | Foreach-Object { $totalRamBytes += $_ }
$totalRamGb = $totalRamBytes / 1GB

术语“ Win32_computerSystem”未被识别为cmdlet的名称
