如何在powershell脚本中传递值列表 [英] How to pass list of value in powershell script

问题描述

这里iam通过加载txt文件来监视cpu使用情况。其中txt文件包含机器名称列表。但我需要将数组或列表传递给脚本而不是从txt文件中读取。

 $ Username ='a'; 
 $ Password ='aa'
 $ pass = ConvertTo-SecureString -AsPlainText $ Password -Force 
 $ Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $ Username，$ pass 
 Invoke-Command -ComputerName qachdc -ScriptBlock {
 
 
 $ SFile =C：\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ = Get-Content $ SFile -ErrorAction SilentlyContinue 
 
 $ Result = @（）
 
 ForEach（$ ServerList中的$ computername）
 
 {
 
 
 $ AVGProc = Get-WmiObject -computername $ computername win32_processor | 
 
 Measure-Object -property LoadPercentage -Average |选择平均值
 
 $ OS = gwmi  - 类win32_operatingsystem -computername $ computername | 
 
 Select-Object @ {Name =MemoryUsage; Expression = {{0：N2} -  f（（$ _。TotalVisibleMemorySize  -  $ _.FreePhysicalMemory）* 100）/ $ _.TotalVisibleMemorySize）}} 
 
 $ vol = Get-WmiObject -Class win32_Volume -ComputerName $ computername -FilterDriveLetter ='C：'| 
 
选择对象@ {Name =C PercentFree;表达式= {{0：N2} -  f（（$ _.FreeSpace / $ _。容量）* 100）}} 
 
 
 
 $结果+ = [ PSCustomObject] @ {
 
 ServerName =$ computername
 
 CPULoad =$（$ AVGProc.Average）％
 
 MemLoad =$ （$ OS.MemoryUsage）％
 
 CDrive =$（$ vol.'C PercentFree'）％
 
} 
 
 $输出报告=
 $ OFS =`r`n
 Foreach（$结果$ $）
 
 {
 $ Outputreport + = $ OFS + $（ $ Entry.Servername）+; + $（$ Entry.CPULoad）+; + $（$ Entry.MemLoad）+; + $（$ Entry.Cdrive）
 
} 
 
 
 
} 
写主机$ Outputreport 
} -credential $ Cred 

我的尝试：



i已尝试过以上代码。但我对脚本概念不熟悉，我不知道如何传递列表或数组而不是从txt文件中读取。

解决方案

Username ='a';

密码='aa'

pass = ConvertTo-SecureString -AsPlainText

Here iam monitoring cpu usage memory by loading txt file. In which txt file contains list of machine name. But i need to pass as array or list to scripts instead of reading from txt file.

$Username = 'a';
$Password = 'aa'
$pass = ConvertTo-SecureString -AsPlainText $Password -Force
$Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$pass
Invoke-Command -ComputerName  qachdc -ScriptBlock {


$SFile = "C:\f\ServerList.txt"  

$ServerList = Get-Content $SFile -ErrorAction SilentlyContinue 

$Result = @() 

ForEach($computername in $ServerList) 

{
  

$AVGProc = Get-WmiObject -computername $computername win32_processor | 

Measure-Object -property LoadPercentage -Average | Select Average

$OS = gwmi -Class win32_operatingsystem -computername $computername |

Select-Object @{Name = "MemoryUsage"; Expression = {"{0:N2}" -f ((($_.TotalVisibleMemorySize - $_.FreePhysicalMemory)*100)/ $_.TotalVisibleMemorySize) }}

$vol = Get-WmiObject -Class win32_Volume -ComputerName $computername -Filter "DriveLetter = 'C:'" |

Select-object @{Name = "C PercentFree"; Expression = {"{0:N2}" -f  (($_.FreeSpace / $_.Capacity)*100) } }

   

$result += [PSCustomObject] @{ 

        ServerName = "$computername"

        CPULoad = "$($AVGProc.Average)%"

        MemLoad = "$($OS.MemoryUsage)%"

        CDrive = "$($vol.'C PercentFree')%"

    }

    $Outputreport = ""
    $OFS = "`r`n"
    Foreach($Entry in $Result) 

        { 
          $Outputreport += $OFS + $($Entry.Servername) + ";" +  $($Entry.CPULoad) + ";" + $($Entry.MemLoad) + ";" + $($Entry.Cdrive)
         
        }

       

}
Write-Host $Outputreport
} -credential $Cred 

What I have tried:

i have tried above code. But iam new to scripting concepts, I dont no how to pass as list or array instead of reading from txt file.

解决方案

Username = 'a';

Password = 'aa'

pass = ConvertTo-SecureString -AsPlainText
