Powershell

Question

我是powershell的新手，现在我有两个脚本，一个是获取远程服务器的IP，另一个是获取远程服务器的具体服务启动时间，我需要显示远程服务器的IP和具体的服务启动时间，有人可以吗指导我如何合并这两个脚本。

下面是我的两个脚本。

$servers = gc -path D:\Ted\Computers.txt

$Job = get-wmiobject win32_networkadapterconfiguration -computer $servers -filter "IPEnabled='True'" -asjob

$results = $job | receive-job

$results


get-job | wait-job

receive-job job* | select IPAddress

另一个获取服务开始时间的是

$servers = gc -path D:\Ted\Computers.txt

$check = get-wmiobject win32_process -computer $servers -Filter "Name='aspnet_state.exe'" -asjob

$results = $check | receive-job

$results


get-job | wait-job

receive-job job* | Select-Object name, processId, @{Name="StartTime"; Expression={ $_.ConvertToDateTime( $_.CreationDate )}}

最后我需要知道一件事，如果我对这个脚本使用asjob，那意味着它是多线程执行？

抱歉我的英语不好，谢谢你的好心帮助。

可能有更简洁的方法来执行此操作，但这是我对您的问题的看法。看起来您似乎需要某种方法将每台计算机与两个 WMI 查询的输出相关联。如果需要运行并行使用作业，则需要更多工作，但这里是串行版本。

Get-Content -Path D:\Ted\Computers.txt | ForEach-Object {
    $ip = Get-WmiObject Win32_NetworkAdapterConfiguration -Computer $_ -Filter "IPEnabled='True'" | Select-Object IPAddress
    $process = Get-WmiObject Win32_Process -Computer $_ -Filter "Name='aspnet_state.exe'" | Select-Object Name, ProcessId, @{ Name="StartTime"; Expression = { $_.ConvertToDateTime($_.CreationDate) } }

    @{
        Computer = $_
        Ip = $ip
        Name = $process.Name
        ProcessId = $process.ProcessId
        StartTime = $process.StartTime
    }
}

并行版本应该是这样的：

# A collection that stores all the jobs
$AllJobs = @()

# A collection that stores jobs correlated with the computer
$ComputerJobs = Get-Content -Path D:\Ted\Computers.txt | ForEach-Object {
    $ipJob = Get-WmiObject Win32_NetworkAdapterConfiguration -Computer $_ -Filter "IPEnabled='True'" -AsJob 
    $AllJobs += $ipJob

    $processJob = Get-WmiObject Win32_Process -Computer $_ -Filter "Name='aspnet_state.exe'" 
    $AllJobs += $processJob

    @{
        Computer = $_
        IpJob = $ipJob
        ProcessJob = $processJob
    }
}

# Wait for everything to complete
Wait-Job -Job $AllJobs

# Iterate the correlated collection and expand the results
$ComputerJobs | ForEach-Object {
    $ip = Receive-Job -Job $_.IpJob | Select-Object IPAddress
    $process = Receive-Job -Job $_.ProcessJob | Select-Object Name, ProcessId, @{ Name="StartTime"; Expression = { $_.ConvertToDateTime($_.CreationDate) } }

    @{
        Computer = $_.Computer
        Ip = $ip
        Name = $process.Name
        ProcessId = $process.ProcessId
        StartTime = $process.StartTime
    }
}
