为什么此脚本无法替换主机文件? [英] Why is this script failing to replace the hosts file?

问题描述

我们要更改要添加到站点的移动PC的主机文件.但是，客户端不太熟悉计算机，这就是为什么我想创建一个批处理文件来为它们进行更新的原因.

We want to make a change to hosts file of our mobile PC we are adding to our sites. However the client isn't so well versed with computers, that's why I wanted to create a batch file to do the update for them.

想法是-制作带有原始副本的原始副本. -更新主机文件.

The idea is to -Make a copy of the original with the date it was copied. -Update the hosts file.

由于要处理win 10和7，我们发现有时我们不能直接更新主机文件而不先复制它，然后覆盖原始文件. 因此，我认为可行的过程就是这样.

Due to dealing with win 10 and 7 we found out sometimes we cant straight update the hosts file without copying it first and then override the original. Therefore the procedure I thought would work is this.

1. 带有原件复制日期的原件副本.
2. 将主机复制到桌面.
3. 更新桌面上的主机文件.
4. 覆盖原始主机文件.
5. 成功或失败的消息.

您可以看到该程序看起来并不那么困难，但是由于特权错误，我遇到了一个错误. 因此，由于客户的知识不足，我想尝试通过批处理文件来提升它.

You can see the program doesn't look so difficult, but I encountered an error due to privileges error. So due to our clients having not enough knowledge, I wanted to try and elevate it though my batch file.

我在这里捆绑搜索，找到了一个帖子"

I'v tied searching here and found a post "How can I auto-elevate my batch file, so that it requests from UAC administrator rights if required?". But unfortunately my VBS and batch knowledge isn't that high and I hoped someone might help me decipher it.

我创建的代码:

::the copy to desktop command                                                                         xcopy /s C:\Windows\System32\drivers\etc\hosts %userprofile%\desktop

::the update of hosts file                                                                            
echo www.qpv-view.info xxx.xxx.xxx.xxx >hosts

::the date for the copied hosts file                                                               
@echo off                                                                                              
for /f "delims=" %%a in ('wmic OS Get localdatetime  ^| find "."') do set dt=%%a                       
set YYYY=%dt:~0,4%                                                                                     
set MM=%dt:~4,2%                                                                                       
set DD=%dt:~6,2%                                                                                       set stamp=Oldhosts_%YYYY%%MM%%DD%                                                                     
copy /y C:\Windows\System32\drivers\etc\hosts C:\Windows\System32\drivers\etc\%stamp%                                          

::The override of the updated file                                                                    
move /s/Y %userprofile%\desktop\hosts C:\Windows\System32\drivers\etc

end

启动时，该副本可以正常工作.但是，更新部分需要提升的特权. 但是，如果我以提升的特权启动脚本，则不会发生复制.

When I launch, the copy works fine. However the update part requires elevated privileges. However if I start the script with elevated privileges the copy doesn't occur.

推荐答案

在使用提升的特权时，您似乎无法复制到%userprofile%\desktop！

It seems that you cannot copy to %userprofile%\desktop while using elevated privileges!

所以我只是将文件复制到drivers文件夹，并且一切运行正常.

So I just copied the file to drivers folder and all ran fine.

@echo off
for /f "delims=" %%a in ('wmic OS Get localdatetime  ^| find "."') do set dt=%%a
set YYYY=%dt:~0,4%
set MM=%dt:~4,2%
set DD=%dt:~6,2%
set stamp=Oldhosts_%YYYY%%MM%%DD%

copy /y C:\Windows\System32\drivers\etc\hosts C:\Windows\System32\drivers\etc\%stamp%
copy /y C:\Windows\System32\drivers\etc\hosts C:\Windows\System32\drivers

echo www.qpv-view.info 172.16.10.60 >C:\Windows\System32\drivers\hosts

move /y C:\Windows\System32\drivers\hosts C:\Windows\System32\drivers\etc
