如何讓腳本在計算機上運行remotelly？

Question

我寫了一個腳本，用於從forrest/domain收集硬件和軟件信息。我已經閱讀了幾篇關於從服務器上的計算機上運行PS腳本的文章，但我想做相反的事情。

你怎麼知道腳本是「遠程訪問」的。 我見過beeing使用這個命令：

Invoke-Command -ComputerName {serverName} –ScriptBlock { commands } 

是否有任何其他的選擇比計算機名？我想，這不是exclussive爲幾臺電腦可以有相同的名字..

這是我的腳本：

try{ 
    $ConfirmPreference="none" 
    $error.clear() 
    $erroractionpreference = "silentlycontinue" 

    #Gets the date of this day, used as name for XML-file later.  
    $a = get-date -uformat "%Y_%m_%d" 

    #Saves computername to compname variable(HELPER) 
    $compname = gc env:computername 

    #Gets the path to directory for all saved files and folders 
    $scriptpath = Split-Path -parent $myinvocation.MyCommand.Definition 

    #PC Serial Number, is used as name for directory containing XML files for this computer. 
    $serialnr = gwmi win32_bios | select -Expand serialnumber 

    #Creates a folder with the name of the computers hardware serialnumber if it does not exist. 
    if(!(Test-Path -path $scriptpath\$serialnr)) { 
     New-item -path $scriptpath -name $serialnr -type directory 
    } 

    #Username 
    $username = gc env:username 

    #System Info 
    gwmi -computer $compname Win32_ComputerSystem | ForEach {$siname = $_.Name; $simanufacturer = $_.Manufacturer; $simodel = $_.Model} 

    #Graphic card 
    $gpuname = gwmi win32_VideoController | select -Expand Name 

    #Processor Info 
    gwmi -computer $compname Win32_Processor | ForEach-Object {$cpuname = $_.Name; $cpumanufacturer = $_.Manufacturer; $cpucores = $_.NumberOfCores; $cpuaddresswidth = $_.AddressWidth} 

    #Memory 
    $totalmem = 0 
    $memsticks = gwmi -Class win32_physicalmemory 
    foreach ($stick in $memsticks) { $totalmem += $stick.capacity } 
    $totalmem = [String]$($totalmem/1gb) + " GB" 

    #Drive  
    $totalspace = 0 
    $totalsize = gwmi -Class win32_logicaldisk 
    foreach($size in $totalsize) { $totalspace += $size.size } 
    $totalspace = "{0:N2}" -f ($totalspace/1Gb) + " GB" 

    #Install time for windows OS 
    $utctime = get-wmiobject win32_OperatingSystem | select-object -expandproperty installDate 
    $installtime = [System.Management.ManagementDateTimeConverter]::ToDateTime($utctime); 
    $installtime = Get-Date $installtime -uformat "%d/%m/%Y %X"

對於-ComputerName參數，你可以使用NETBIOS名稱，IP地址，或完全合格的域名。有關更多詳細信息，請參見Invoke-Command on TechNet。

似乎您的腳本「僅」將數據保存在正在運行的計算機上，您可能會希望它返回某些內容以便與Invoke-Command一起使用。
