Powershell 操作主机文件 [英] Powershell to manipulate host file

问题描述

我正在查看是否可以创建 powershell 脚本来更新主机文件中的内容.

I am looking at to see if I can create powershell script to update the contents in the host file.

有人知道是否有任何示例使用 powershell 或任何其他脚本语言来操作主机文件?

Anybody know if there are any examples that manipulate the host file using powershell or any other scripting lanaguages?

谢谢.

推荐答案

首先，如果您使用的是 Vista 或 Windows 7，请确保从提升的提示符处运行这些命令:

First up, if you're on Vista or Windows 7 make sure you run these commands from an elevated prompt:

# Uncomment lines with localhost on them:
$hostsPath = "$env:windir\System32\drivers\etc\hosts"
$hosts = get-content $hostsPath
$hosts = $hosts | Foreach {if ($_ -match '^\s*#\s*(.*?\d{1,3}.*?localhost.*)')
                           {$matches[1]} else {$_}}
$hosts | Out-File $hostsPath -enc ascii

# Comment lines with localhost on them:
$hosts = get-content $hostsPath
$hosts | Foreach {if ($_ -match '^\s*([^#].*?\d{1,3}.*?localhost.*)') 
                  {"# " + $matches[1]} else {$_}} |
         Out-File $hostsPath -enc ascii

鉴于此，我认为您可以了解如何根据需要使用正则表达式来操作条目.

Given this I think you can see how to use a regex to manipulate entries as necessary.
