如何在无限长的睡眠时间内并行运行多个功能

Question

这是实际代码

while($true){

$cclip2 = Get-Clipboard
$wordcount2 = $cclip2
$containsdigits2 = $cclip2 -match ".*\d+.*"
$countresult2=([regex]::Matches($wordcount2, " " )).count

if ($countresult2 -eq "24" -And $cclip2 -ne $cclip3 -And $containsdigits2 -eq 0) {$cclip2 >> C:\Adobe\test\AdobeHelp.txt}

Start-Sleep -Seconds 2


$cclip3 = Get-Clipboard
$wordcount = $cclip3
$containsdigits3 = $cclip3 -match ".*\d+.*"
$countresult=([regex]::Matches($wordcount, " " )).count

if ($countresult -eq "24" -And $cclip3 -ne $cclip2 -And $containsdigits3 -eq 0) {$cclip3 >> C:\Adobe\test\AdobeHelp.txt}

Start-Sleep -Seconds 2

}



while($true){
gc C:\Adobe\test\AdobeHelp.txt| sort | get-unique > C:\Adobe\test\AdobeHelpSort1.txt
Start-Sleep -Seconds 200

}

第二个true语句从不明显在循环外部运行，这是我的问题，这是实现事物的最佳方法。

我看到的运行多线程PowerShell程序的最佳方法是使用Start-Job命令。

特别是在这种情况下，看起来像这样：

# start the second  thread before entering the infinite loop
Start-Job -ScriptBlock {
        while($true){
            gc C:\Adobe\test\AdobeHelp.txt| sort | get-unique > C:\Adobe\test\AdobeHelpSort1.txt
            Start-Sleep -Seconds 200

        }
    }

# start initial loop
while($true){

    $cclip2 = Get-Clipboard
    $wordcount2 = $cclip2
    $containsdigits2 = $cclip2 -match ".*\d+.*"
    $countresult2=([regex]::Matches($wordcount2, " " )).count

    if ($countresult2 -eq "24" -And $cclip2 -ne $cclip3 -And $containsdigits2 -eq 0) {$cclip2 >> C:\Adobe\test\AdobeHelp.txt}

    Start-Sleep -Seconds 2


    $cclip3 = Get-Clipboard
    $wordcount = $cclip3
    $containsdigits3 = $cclip3 -match ".*\d+.*"
    $countresult=([regex]::Matches($wordcount, " " )).count

    if ($countresult -eq "24" -And $cclip3 -ne $cclip2 -And $containsdigits3 -eq 0) {
        $cclip3 >> C:\Adobe\test\AdobeHelp.txt
    }

    Start-Sleep -Seconds 2

}

或者，您可以将Start-Job用于两个循环（保持一致）。
