Question

我有一个powershell脚本，它将许多主机名作为输入，然后在其中安装IE11和Office 2010。目前它将这些安装在一个主机中，然后继续下一个主机等。这只是浪费时间，因为一个安装不会影响另一个。那我怎么能让它并行运行呢？ TIY 这是我的代码：

Write-Host "*************************************************"
Write-Host "Welcome to the IE11/Office 2010 Remote Installer"
Write-Host "*************************************************"

$pclist = (Read-Host "Enter the pc names seperated by comma").Split(",")

foreach ($pc in $pclist) {
    Write-Host "-------------------------------------------------------------------------------------------------------"
    Write-Host "Installing IE in $($pc). Please look for the exit code in the end. Exit code 0 means successful"
    psexec -s \\$pc \\myserver\directory\PREREQ.BAT
    psexec -s \\$pc \\myserver\directory\INSTALL.BAT
    Write-Host "-------------------------------------------------------------------------------------------------------"
    Write-Host "Installing office in $($pc). Please look for the exit code in the end. Exit code 0 means successful"
    psexec -s \\$pc \\myserver\directory\INSTALL.BAT
    Write-Host "-------------------------------------------------------------------------------------------------------"
    Write-Host "RESTART THE PC TO APPLY CHANGES"
}

查看Start-Job，Wait-Job和Receive-Job 我删除了Write-Host语句，使其更易于阅读。

$jobs = $pclist | % {
    Start-Job -ScriptBlock {
        $target = $args[0]
        psexec -s \\$target \\myserver\directory\PREREQ.BAT
        psexec -s \\$target \\myserver\directory\INSTALL.BAT
        psexec -s \\$target \\myserver\directory\INSTALL.BAT
    } -ArgumentList $_
}
$jobs | Wait-Job | Receive-Job

当作业仍然通过Register-EngineEvent运行时接收输出的更新：

$null = Register-EngineEvent -SourceIdentifier PcInstallMsg -Action {
    Write-Host $Event.MessageData
}

$jobs = $pclist | % {
    Start-Job -ScriptBlock {
        $null = Register-EngineEvent -Forward -SourceIdentifier PcInstallMsg

        $target = $args[0]

        $null = New-Event -SourceIdentifier PcInstallMsg -MessageData "Install pre-req stuff to $target"
        Start-Sleep -Seconds 2

        $null = New-Event -SourceIdentifier PcInstallMsg -MessageData "Install main stuff to $target"
        Start-Sleep -Seconds 2

        $null = New-Event -SourceIdentifier PcInstallMsg -MessageData "Do cleanup bc I was messy on $target"
        Start-Sleep -Seconds 2

    } -ArgumentList $_
}
while (-not (Wait-Job $jobs -Timeout 1)) {
}
$jobs | Receive-Job

Unregister-Event -SourceIdentifier PcInstallMsg

如何在PowerShell中动态数组的内容中并行运行命令？
