如何让脚本在计算机上运行remotelly？

Question

我写了一个脚本，用于从forrest/domain收集硬件和软件信息。我已经阅读了几篇关于从服务器上的计算机上运行PS脚本的文章，但我想做相反的事情。

你怎么知道脚本是“远程访问”的。 我见过beeing使用这个命令：

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

是否有任何其他的选择比计算机名？我想，这不是exclussive为几台电脑可以有相同的名字..

这是我的脚本：

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"

对于-ComputerName参数，你可以使用NETBIOS名称，IP地址，或完全合格的域名。有关更多详细信息，请参见Invoke-Command on TechNet。

似乎您的脚本“仅”将数据保存在正在运行的计算机上，您可能会希望它返回某些内容以便与Invoke-Command一起使用。
