从txt文件读取行以重命名服务器-Powershell

Question

I'm trying to read a certain line from a text file using powershell, which can then be used to run with netdom to rename each DC. The line is always line number 3 and starts with Servername= . I need to grab the text after the equals sign to then use with netdom. It was working at first, but netdom would complain about the syntax. Is this because it is a string?. Now servername is returned as the full line:

C:\config.txt:3:ServerName servername

and not just the servername.

 $servername = Select-String -Path "C:\config.txt" -Pattern "servername="
 $servername = $servername.tostring().split("=")
 netdom renamecomputer localhost /NewName:$servername /force

Answer 1

我认为您必须在第二行后面附加[1]才能选择所需的拆分字符串，即：

$servername = $servername.tostring().split("=")[1]
