Powershell计算机列表

我如何使用服务器列表来实现这一点

已尝试执行

$ComputerList=gc

，但似乎不起作用 用一台计算机就可以了

$Start = (Get-Date).AddMinutes(-120)
$ComputerList = $env:ComputerName 
$Events = gc C:\Temp\ErrorCodes.txt

# Getting all event logs
Get-EventLog -AsString -ComputerName $Computername |
ForEach-Object {
# write status info
Write-Progress -Activity "Checking Eventlogs on \\$ComputerName" -Status $_

# get event entries and add the name of the log this came from
Get-EventLog -LogName $_ -EntryType Error, Warning -After $Start -ComputerName $ComputerName -ErrorAction SilentlyContinue |
  Add-Member NoteProperty EventLog $_ -PassThru | Where-Object {$Events -contains $_.eventid}

} |
# sort descending
Sort-Object -Property EventLog |
# select the properties for the report
Select-Object EventLog, EventID, TimeGenerated, EntryType, Source, Message 
# output into grid view window
Out-GridView -Title "All Errors & Warnings from \\$Computername"

将其强制为数组。。否则，如果只有一项，它将作为字符串输入

$ComputerList=@（gcc:\folder\ComputerList.txt）
