Powershell foreach 暂停后执行

Question

我创建了一个脚本来读取名称列表并使用“Resolve-DnsName”将它们转换为 IP。我希望用户只需双击脚本并阅读输出。

Write-Host -ForegroundColor Green -BackgroundColor DarkRed "

Write-Host "`n`n"


$estacoes = @(
    'esbsa9908ee43',

    'esbsa9908ee18',
    '7417191543116',
    '7417191543242'
)

ForEach ($estacao in $estacoes){
    Resolve-DnsName -ErrorAction Continue -Type A -QuickTimeout -Name $estacao | Select-Object Name,IpAddress
    }

Pause

碰巧最后的“pause”命令在“foreach”之前执行。

我似乎找不到原因。你们能帮忙吗？

Answer 1

它看起来类似于管道输出和写入主机输出发生的有趣事情，其中写入主机输出将首先出现，即使它在管道之后运行。这是更改输出顺序的一种方法：

$estacoes = echo microsoft.com yahoo.com
$result = ForEach ($estacao in $estacoes){
    Resolve-DnsName -ErrorAction Continue -Type A -QuickTimeout -Name $estacao | 
      Select-Object Name,IpAddress 
    }

$result | format-table

pause

# didn't work
# 'Press Enter to continue...:'
# [void][console]::readkey()

Powershell foreach 暂停后执行

Powershell foreach executing after pause

powershell

foreach

pause
