Question

我正在尝试执行以下操作：

Workflow spawnInParallel() {
  $task1 = { "Dir C:\; pause" }
  $task2 = { "Dir C:\Windows; pause" }
  $task3 = { "ng build --prod; pause" }

  $tasks = $task1, $task2, $task3    
  ForEach -Parallel ($task in $tasks) {
    start powershell "& $task"
  }
}

spawnInParallel

我将DOS命令封装为字符串只是因为我不知道更清洁的方式。

我不知道这是否是Workflow，Jobs或其他任务。希望保持干净简洁..使用PS 5.1。

所需的结果将是原始的，加上3个新的Powershell Windows运行命令而不是立即关闭。

使用更新的已接受答案实施

Workflow showParallel() {    
    param([String[]] $procs)

    $tasks = @()
    foreach ($proc in $procs) {
        $tasks += " cmd.exe /c 'Echo Running $proc&$proc&pause' "
    }

    foreach -parallel ($task in $tasks) {
        Start-Process powershell "-c $task"
    }
}

$app1BuildCmd = "ng build --app app1 --prod --output-path $app1Root"
$app2BuildCmd = "ng build --app app2 --prod --output-path $app2Root"
$app3BuildCmd = "ng build --app app3 --prod --output-path $app3Root"

showParallel -procs @($app1BuildCmd , $app2BuildCmd , $app3BuildCmd )

将一堆DOS命令串在一起可能很棘手，但可以完成或进一步重构......

这似乎可以做你想要的，或者至少可以用来实现你的最终结果......

Workflow showParallel()
{
    $t1 = {
        cmd /k echo t1 in cmd here...`&pause
    }
    $t2 = {
        cmd /k echo t2 in cmd here...`&pause
    }
    $t3 = {
        cmd /k echo t3 in cmd here...`&pause
    }

    $tasks = $t1, $t2, $t3
    foreach -parallel ($task in $tasks)
    {
        Start-Process powershell "-noexit `"$task`""
    }
}

showParallel

根据OP的请求更新

Workflow showParallel()
{
    $name1 = 't1!'
    $run1 = "echo $name1 in cmd here..."

    $t1 = "
        cmd.exe /c '$run1&pause'
    "

    $t2 = {
        cmd /c echo t2 in cmd C here...`&pause
    }
    $t3 = {
        cmd /k echo t3 in cmd K here...`&pause
    }

    $tasks = $t1, $t2, $t3
    foreach -parallel ($task in $tasks)
    {
        $task
        #Start-Process powershell "-noexit -c $task"
        Start-Process powershell "-c $task"
    }
}

showParallel

在新窗口中并行运行Powershell .. shell命令（不是脚本）并等待
