每个脚本的 Powershell 不按顺序

Question

对于每条语句，我都有以下 PowerShell，该语句循环遍历大约 50 个邮箱的列表，并在每个邮箱上运行 2 个脚本。这两个脚本大约需要一个小时才能完成。由于 PowerShell 的顺序性质，这将需要 ~50 个邮箱 * 1 小时 = 50 小时。

PowerShell 是否可以同时并行地在每个邮箱上运行脚本？

Foreach($mailbox in $mailboxes){
    Write-Host "$(Get-TimeStamp) Start of adding contacts $mailbox"
        & $scriptPath -Mailbox  $mailbox.UserPrincipalName -ClientSecret $clientSecret -ClientID $clientID -TenantID $tenantID -CSVPath $csvPath
    Write-Host "$(Get-TimeStamp) Start of deduplicating contacts $mailbox"
        & $scriptPath2 -Mailbox  $mailbox.UserPrincipalName -ClientSecret $clientSecret -ClientID $clientID -TenantID $tenantID 
}

Answer 1

使用

Start-Job

怎么样？

$jobs = @()

foreach ($mailbox in $mailboxes) {
    $job1 = Start-Job -ScriptBlock {
        Write-Host "$(Get-TimeStamp) Start of adding contacts $mailbox"
        & $scriptPath -Mailbox  $mailbox.UserPrincipalName -ClientSecret $clientSecret -ClientID $clientID -TenantID $tenantID -CSVPath $csvPath
    }

    $job2 = Start-Job -ScriptBlock {
        Write-Host "$(Get-TimeStamp) Start of deduplicating contacts $mailbox"
        & $scriptPath2 -Mailbox  $mailbox.UserPrincipalName -ClientSecret $clientSecret -ClientID $clientID -TenantID $tenantID 
    }

    $jobs += $job1, $job2
}

# Wait for all jobs to finish and retrieve results (if any)
$jobs | Wait-Job
$jobResults = $jobs | Receive-Job

# Clean up jobs and display results if needed
$jobs | Remove-Job
$jobResults
