Ubuntu automatically selects the fastest source script

From: http://hi.baidu.com/fancycedar/blog/item/13711c546163821a3b2935f6.html

This book was moved between the lab and the dormitory. One was CERNET, and the other was Nb's Netcom. To install something, we had to manually change the new software source!

It is estimated that you will be worried about moving between different networks!
How can I know which is the fastest software source for my network?
How can I automatically change the software source easily?
How is technology lazy?
Let's look at the answer.
I'm not the original author, but I don't know who it is ...... I changed it to ubuntu8.04, and later versions can be easily implemented by changing the script. Share some good things with you!

First, we need three files: getfastsources,. ubuntu_mirrors,. ubuntu_mirrors.list. Note that there is "." in front of the last two files, which is a hidden file. When the file name can be changed, you can change the file name as you like. Put getfastsources in/bin and have executable permissions. ubuntu_mirrors,
. Ubuntu_mirrors.list is placed under/home/xxxx.

Then let's take a look at the specific content of each file.
1. getfastsources

Mirrors_list = $ home/. ubuntu_mirrors.list # You can change the file name and storage location to store all the source lists.

Version = "hard" # When the Ubuntu version changes, change this "hard" to the corresponding version number.

3. ubuntu_mirrors
Create an empty file.

Finally, make sure that your getfastsources is in/bin, and. ubuntu_mirrors and. ubuntu_mirrors.list are in your home directory, and then you can execute getfastsources!
It takes about 30 seconds to test each source.
If:
Fancy @ fancy :~ $ Getfastsources
