Question

我正在尝试编写一个简短的脚本，该脚本将获取域中所有计算机的列表，然后在其上运行Get-Printer以获取每台计算机上所有已安装打印机的列表。

要获取域中的计算机列表，我想使用“net view”，所以我尝试了

net view | ForEach-Object {Get-Printer -ComputerName $_}

但这不起作用。相反，我只是在网络视图中为每台PC获得了一条“后台处理程序服务无法访问”。

手动将电脑名称输入“Get-Printer”非常有效，我实际编写了一个工作脚本，在文本中搜索PC名称后将网络视图的结果输出到.txt文件，然后从中读取每行文本文件并按顺序输入“Get-Printer”。但是我希望能够扩展这些代码来集中管理打印机，所以我需要在一条线上工作，我认为这是可行的。

任何人都可以解释我在这里缺少的东西吗？ ForEach如何在Powershell 4中实际运行？

以下是我的工作代码，它写入文件然后从中读取：

$PCs = net view /all | Select-String "\\"

$a = ForEach ($Line in $PCs)

{   $Line -Replace(" ","")

}

$a | Out-file -FilePath C:\Users\esmith\Desktop\test.txt -Encoding ascii

Get-content C:\Users\esmith\Desktop\test.txt | ForEach-Object {Get-Printer -cn $_} | Out-file -FilePath C:\Users\esmith\Desktop\output.txt

是一个DOS命令行，它返回文本输出。 PowerShell管道适用于对象而不是文本，因此在这种情况下不能很好地结合使用。（从技术上讲：字符串也是对象，但不是你期望的那种对象）。

您可以使用本机PowerShell cmdlet Get-AdComputer获取已加入计算机的域列表作为PowerShell对象，然后您可以将其输入管道。

这样的事情应该有效：

<style name="AppThemeActionBar" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

The Get-Printer cmdlet does except pipeline input directly，所以这也应该有效（不需要显式的ForEach-Object）：

net view

Powershell 4管道和管道Get-Printer交互
