Question

我正在尝试创建powershell脚本（获得更高级的功能……JK。Powershell提供的功能比批处理文件还多，我想使用其中的一些功能。）

所以，这是我的批处理脚本：

:Start 
@echo off 
set /p password="Password:" 
:Nextcomp 
set /p computer="Computer name:" 
wmic /user:username /password:%password% /node:"%computer%" memorychip get capacity 
set /P c=Do you want to get info about another computer (y/n)? 
if /I "%c%" EQU "y" goto :Nextcomp 
if /I "%c%" EQU "n" goto :End goto :choice 
pause 
:End

这就是我的发现：Script 我根据需要对其进行了修改，但是每当我尝试运行此脚本时，都会以错误的方式得到它-它向我显示了整个脚本，直到最后它才询问我有关计算机的名称：

$resultstxt = "C:\Users\user\Documents\results.csv"
Param(
     [Parameter(Mandatory=$true, Position=0, HelpMessage="Password?")]
     [SecureString]$password
   )
$pw = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($password))
$Computer = Read-Host -Prompt 'Computer name'
$out = @()
If (!(Test-Connection -ComputerName $Computer -Count 1 -Quiet)) { 
    Write-Host "$Computer not on network."
    Continue 
}
foreach($object in $HostList) {
$RAM = get-wmiobject -user user -password $pw -computername $object.("Computer")-class win32_physicalmemory 
$DeviceInfo= @{}
$DeviceInfo.add("RAM", "$([math]::floor($RAM.Capacity/ (1024 * 1024 * 1024 )) )" + " GB" )
$DeviceInfo.add("Computer Name", $vol.SystemName)
$out += New-Object PSObject -Property $DeviceInfo | Select-Object "RAM"
Write-Verbose ($out | Out-String) -Verbose             
$out | Export-CSV -FilePath $resultstxt -NoTypeInformation

}

您可能已经猜到了，我有很多字段，但是它们都是相似的，并且我从很多资源中借来了，但主要来自“脚本”链接。

我想要的是：

隐藏密码
在每台新计算机（请参阅3.）之后，在当前计算机之后（在下一行）添加信息，并将信息导出为CSV
询问是否要获取有关另一台计算机的信息，请用“ y”键表示是，用“ n”键表示否。
使脚本正常工作

我发现了问题1，但尚未测试，所以...行得通吗？接下来，我发现了问题2，但是它将以一种不易阅读的格式显示所有信息，而不是我需要的所有信息，并且全部显示在一个单元格中。最终，我发现大约3，但这是行不通的。我不能说我挖了整个互联网，但我希望你们（还有gal？）能帮我弄清楚。解决这三个问题不应该那么困难，毕竟这不是一个超级复杂的脚本，对吗？我当前的脚本只有31行，包括空格。

Answer 1

这是从一组系统中获取基本系统信息的一种方法的演示。它使用CIM cmdlet，因为它们比WMI cmdlet更快（大多数时间），将datetime信息显示为标准datetime对象，并且不建议过时。

它还使用Invoke-Command cmdlet进行远程并行处理，并设置为忽略错误，以便无响应的系统不会浪费您的时间。

要获得结构良好的CSV文件，请通过$RespondingSystems将Export-CSV集合发送到该文件。

有关环绕任何给定代码块的循环演示，请看一下...

$Choice = ''

while ([string]::IsNullOrEmpty($Choice))
    {
    $Choice = Read-Host 'Please enter a valid computer name or [x] to exit '
    # replace below with real code to check if $ComputerName is valid
    if ($Choice -eq $env:COMPUTERNAME)
        {
        $ValidCN = $True
        }
        else
        {
        $ValidCN = $False
        }
    if (-not $ValidCN -and $Choice -ne 'x')
        {
        # insert desired error notice
        [console]::Beep(1000, 300)
        Write-Warning ''
        Write-Warning ('Your choice [ {0} ] is not a valid computer name.' -f $Choice)
