虽然我不完全确定这个问题属于 Stack Overflow，但您是否查看过 PS Cmdlet for Get-Content?在 使用 Get-Content 中查看 TechNet 上的示例中如何使用它Cmdlet.
Although I'm not entirely sure that this question belongs on Stack Overflow, have you looked at the PS Cmdlet for Get-Content? Look how it's used in the examples on TechNet in Using the Get-Content Cmdlet.
示例:
Get-Content c:\scripts\test.txt | Foreach-Object {Get-Wmiobject -computername $_ win32_bios}
更新:以上指向 TechNet 的链接已断开，但 Chad Miller 脚本专家的帖子在评论中提到了 使用 PowerShell 解决遗留重定向问题 提供了三个选项:-use CMD/c、Echo 和 Get-Content.
Update: Above link to TechNet is broken, but mentioned in comment by Chad Miller Scripting Guy's post Working Around Legacy Redirection Issues with PowerShell gives three options: -use CMD /c, Echo, and Get-Content.
