powershell - 获取内容问题

Question

基本的Powershell问题在这里-我在c:\ temp \ servers.txt文件中有两台计算机，并想查询tcpip.sys文件的版本信息。我不断遇到错误，但它似乎也可以正常工作。

PS C:\Windows\System32\drivers> Get-Content C:\temp\servers.txt | ForEach-Object (Get-ChildItem c:\windows\system32\drivers\tcpip.sys).Versioninfo

我收到以下错误:

ForEach-Object :> Cannot bind parameter 'Process'. Cannot convert the "File:
C:\windows\system32\drivers\tcpip.sys InternalName: tcpip.sys OriginalFilename: tcpip.sys.mui FileVersion: 6.1.7600.16385 (win7_rtm.090713-1255) FileDescription: TCP/IP Driver Product:

Answer 1

您需要为每个服务器构造一个UNC路径:

Get-Content C:\temp\servers.txt | ForEach-Object {
    (Get-ChildItem \\$_\c$\windows\system32\drivers\tcpip.sys).Versioninfo 
}

您还需要使用花括号而不是括号，这就是您出错的原因。
