运行多个脚本实例

Question

我在操作中心工作，每台计算机上有10个屏幕。主计算机通过浏览器窗口中的chrome显示了许多遥测数据和仪表板，图形，动画以及许多其他有用的信息。每次重启动计算机时，这都是很乏味的，所以我很高兴找到这个原始项目：Chrome-kiosk来自https://alextomin.wordpress.com/2015/04/04/04/10/kiosk-mode-ing-mode-in-----mode-in---------Windows-Chrome-Multiple-Displays/

它在我们的运营中心中的自动起动器非常有效，因此我对其功能的这一方面感到满意。但是后来我开始思考：如果我能以某种方式暂时在板上显示一个网页，并且在设定的时间段后将其关闭，以便整个办公室可以监视重要的事件，这是否有用。

到目前为止，我想出的是很酷的，工作人员认为它非常有用，但是，它需要更多功能。这些很简单，但是我被困了，我一直在试图弄清楚这片刻。以下是我正在使用的代码。

我无法工作的事情：杀死计时器：我可以通过在我创建的杀戮功能前添加启动等待来使它起作用，但这使得looper.ps1脚本坐在启动器时等待。ps1完成。我如何在不制作looper脚本停止的情况下运行脚本直到其他脚本完成？

如何跟踪打开的每个新的Chrome实例？使用系统ID似乎不起作用，我能做的最好的就是获取chrome和最新实例，这意味着我可以杀死比计时器价值年轻的Chrome实例，但是我正在努力获得这可以工作。

这里的任何建议将不胜感激。

服务器脚本

我将它们放入一个称为C： Scripts iCvt

的文件夹中

looper.ps1-这将不断运行

Set-Location -Path C:scriptsICVT
while ($true) {
    .file_checker.ps1;
}

file_checker.ps1-这是Looper运行的脚本。File_Checker扫描Web.txt和mon.txt的文件夹。两者都必须出现才能执行脚本。

#Checks folder for web.txt and mon.txt . Both must be present for the rest of the script to execute
Set-Location -Path C:scriptsICVT
$a = Test-Path web.txt
$b = Test-Path mon.txt
if (($a -and $b -eq $True)) {
    .launcher.ps1
} else {
    Write-Host "Scanning For Files"
} 
Start-Sleep -Seconds 5

launcher.ps1-这只是原始脚本的修改版本

$chromePath = 'C:Program Files (x86)GoogleChromeApplicationchrome.exe'
$chromeArguments = '--new-window'
$web = (Get-Content -Path web.txt)
$mon = (Get-Content -Path mon.txt)
$timer = (Get-Content -Path $timer.txt)
# if Window not moved (especially on machine start) - try increasing the 
# delay. 
$ChromeStartDelay = 5
Set-Location $PSScriptRoot
. .HelperFunctions.ps1
Chrome-Kiosk $web -MonitorNum $mon
#Delete parameters after use
Start-Sleep -Seconds 5
del web.txt
del mon.txt
del timer.txt

这是通过网络创建Web.txt，timer.txt和mon.txt文件的GUI

为了执行许多功能，您首先需要为Chrome窗口获得一个流程ID。为此，我们需要对Chrome-Kiosk功能进行一些更改以返回该信息。首先，我将Start-Process更改为包括-PassThru参数。这样，我得到一个可以从中获得pid的过程对象。对Get-Process的另一项编辑用于使用ID代替" Chrome"，最后我们Write-Output $Process对象。

function Chrome-Kiosk($Url, $MonitorNum)
{
    Write-Output "starting chrome $Url , monitor: $MonitorNum"
    $Process = Start-Process $chromePath "$chromeArguments $Url" -PassThru
    Start-Sleep -Seconds $ChromeStartDelay
    $window = (Get-Process -Id $Process.Id | where MainWindowHandle -ne ([IntPtr]::Zero) | select -First 1).MainWindowHandle
    $WinAPI::ShowWindow($window, [Tomin.Tools.KioskMode.Enums.ShowWindowCommands]::Restore)
    $Helpers::MoveToMonitor($window, $MonitorNum)
    $Helpers::SendKey($window, '{F11}')
    Start-Sleep -Seconds $ChromeStartDelay
    Write-Output $Process
}

其余的工作是修改启动器脚本以使用杀死计时器。本质上，我们将.txt删除部分拉回您的 file_checker.PS1脚本，以便我们可以启动launcher.ps1作为新的自我包含的PowerShell进程。

file_checker.ps1

#Checks folder for web.txt and mon.txt . Both must be present for the rest of the script to execute
Set-Location -Path C:scriptsICVT
$a = Test-Path web.txt
$b = Test-Path mon.txt
IF (($a -and $b -eq $True)) {
    . .launcher.ps1
    #Delete parameters after use
    del web.txt
    del mon.txt
    del timer.txt
} 
else {
    Write-Host "Scanning For Files"
} 
Start-Sleep -Seconds 5

通过使用修改的Chrome-Kiosk函数，它返回Chrome窗口的过程对象，我们现在可以使用启动器脚本启动，睡眠，然后仅杀死我们启动的Chrome窗口：

启动器.ps1

$chromePath = 'C:Program Files (x86)GoogleChromeApplicationchrome.exe'
$chromeArguments = '--new-window'
$web = (Get-Content -Path web.txt)
$mon = (Get-Content -Path mon.txt)
$timer = (Get-Content -Path $timer.txt)
# if Window not moved (especially on machine start) - try increasing the 
# delay. 
$ChromeStartDelay = 5
Set-Location $PSScriptRoot
. .HelperFunctions.ps1
$Process = Chrome-Kiosk $web -MonitorNum $mon
#Wait some period of time
Start-Sleep -Seconds 60
#Kill the process
Stop-Process $Process
