Powershell

Question

我有一个脚本可以使用 Start-Process 命令创建一些进程。可能有数百个进程运行。该脚本工作得很好，但我希望有人能为我提供一种更优雅的方法来检查我开始的流程是否已全部完成？一个不需要任何输入的方法，因为我正在寻找一个自动化的解决方案。

下面是一个代码示例。

$procList = @()

$cmd = "C:\Windows\SysWOW64\PING.EXE"
$cmdArgs = " nos3nse.com"
$proc1 = Start-Process $cmd -ArgumentList $cmdArgs -PassThru
$proc2 = Start-Process $cmd -ArgumentList $cmdArgs -PassThru
$proc3 = Start-Process $cmd -ArgumentList $cmdArgs -PassThru

$procObject = New-Object psobject -Property @{
    id = $proc1.Id
    name = $proc1.Name
    startTime = $proc1.StartTime
    dtlLogFile = $dtlLogFileTemp
}
$procList += $procObject

$procObject = New-Object psobject -Property @{
    id = $proc2.Id
    name = $proc2.Name
    startTime = $proc2.StartTime
    dtlLogFile = $dtlLogFileTemp
}
$procList += $procObject

$procObject = New-Object psobject -Property @{
    id = $proc3.Id
    name = $proc3.Name
    startTime = $proc3.StartTime
    dtlLogFile = $dtlLogFileTemp
}
$procList += $procObject

# Is there a better way to find out if these jobs have all completed?
$ppFlag = $true
while ($ppFlag) {
  foreach ($proc in $procList) {
    $chkJob = Get-Process -id $proc.id -ErrorAction SilentlyContinue
    if ($chkJob.HasExited -eq $false) 
      { 
        Write-Host ("looping")
        Write-Host ("Sleeping 2 seconds") -ForegroundColor Yellow
        Start-Sleep -Seconds 2
        break #break foreach loop
      }
  } #foreach
  if ($chkJob.HasExited -ne $false) { $ppFlag = $false }
} #while

这个怎么样？

$a = start -NoNewWindow powershell {timeout 10; 'a done'} -PassThru
$b = start -NoNewWindow powershell {timeout 10; 'b done'} -PassThru
$c = start -NoNewWindow powershell {timeout 10; 'c done'} -PassThru
$a,$b,$c | wait-process

Waiting for  0 seconds, press a key to continue ...
Waiting for  0 seconds, press a key to continue ...
Waiting for  0 seconds, press a key to continue ...

a done
b done
c done

等待过程可以与数组一起使用。也许你应该更新你的问题。

1..3 | foreach { start -NoNewWindow powershell {timeout 5; 'done'} -PassThru } | 
  wait-process
