长时间运行的 Powershell 脚本冻结

Question

我们正在使用长时间运行的 PowerShell 脚本来执行许多可能需要极长时间的小操作。大约 30 分钟后，脚本冻结了。我们能够通过按 Ctrl-C 使脚本重新开始运行，这会导致脚本恢复执行而不是终止进程。

是否存在某种脚本超时或机制可以防止 PowerShell 中长时间运行脚本？

Answer 1

由于我的坏习惯，我遇到了这个问题。如果您在控制台 powershell 中选择一点文本，脚本日志将冻结。确保启动大脚本后没有选择任何内容:)

Answer 2

如前所述，当在 powershell 控制台中单击/选择文本时，脚本会停止。您可以像这样禁用此行为：

• 右键单击标题栏

• 选择属性

• 选择选项

• 在编辑选项下，禁用快速编辑模式

注意：您将无法再从 powershell 窗口中选择文本。

试试我的终止计时器脚本。只需将 $ScriptLocation 变量更改为您要运行的脚本即可。然后，该脚本将作为后台作业运行，同时当前窗口跟踪计时器。时间到期后，当前窗口将终止后台作业并将其全部写入日志。

    Start-Transcript C:\Transcriptlog-Cleanup.txt #write log to this location
$p = Get-Process  -Id $pid | select -Expand id  # -Expand selects the string from the object id out of the current process.
Write-Host $p
$BJName = "Clean-up-script"   #Define Background job name

$startTime = (Get-Date) # set start time
$startTime
$expiration = (Get-Date).AddMinutes(2)#program expires at this time
# you could change the expiration time by changing (Get-Date).AddSeconds(20) to (Get-Date).AddMinutes(10)or to hours or whatever you like


#-----------------
#Timer update function setup
function UpdateTime
   {
    $LeftMinutes =   ($expiration) - (Get-Date) | Select -Expand minutes  # sets minutes left to left time
    $LeftSeconds =   ($expiration) - (Get-Date) | Select -Expand seconds  # sets seconds left to left time


    #Write time to console
    Write-Host "------------------------------------------------------------------" 
    Write-Host "Timer started at     :  "  $startTime
    Write-Host "Current time         :  "  (Get-Date)
    Write-Host "Timer ends at        :  "  $expiration
    Write-Host "Time on expire timer :  "  $LeftMinutes "Minutes" $LeftSeconds "Seconds"
    Write-Host "------------------------------------------------------------------" 
    }

    #get background job info and remove the it afterwards + print info
function BJManager   
    {
       Receive-Job -Name $BJName  #recive background job results
       Remove-Job -Name $BJName -Force #remove job
       Write-Host "Retrieving Background-Job info and Removing Job..."
    }
#-----------------
$ScriptLocation = "C:\\Local-scripts\Windows-Server-CleanUp-Script-V2.4(Beta).ps1"  #change this Var for different kind of script locations

Start-Job -Name $BJName -FilePath $ScriptLocation #start this script as background job
# dont start job in the loop.
do{   #start loop

   Write-Host "Working"#start doing other script stuff
   Start-Sleep -Milliseconds 5000  #add delay to reduce spam and processing power
   UpdateTime #call upadate function to print time

   Get-Job -Name $BJName  | select Id, State ,Location , Name
        if((Get-Job).State -eq "Failed")
            {
                BJManager
            }
        elseif((Get-Job).State -eq "Completed")
            {
                BJManager
            }

 }
until ($p.HasExited -or (Get-Date) -gt $expiration) #check exit time

Write-Host "Timer Script Finished"
Get-Job -Name $BJName  | select Id, State ,Location , Name
UpdateTime

BJManager

Start-Sleep -Milliseconds 5000 #give it some time to write to log
Stop-Transcript
Start-Sleep -Milliseconds 5000 #give it some time to stop the logging before killing process
if (-not $p.HasExited) { Stop-Process -ID $p -PassThru } # kill process after time expires

尝试在脚本中添加百分比计算..这样您就可以确定完成需要多少时间...
