SVN over a directory that already exists

I've been reading about using a zsh template file on a scientific computing website. I've never used subversion before but am attempting to learn how to do so. Anyhow, they have a repository on Google code that has the following instructions:

cd /Library

sudo svn co http://zsh-templates-osx.googlecode.com/svn/trunk/Library/init

cd /private

sudo svn co http://zsh-templates-osx.googlecode.com/svn/trunk/etc

I have no problem with the first two lines because there is no folder located in /Library called init. The problem I'm facing is with the second two lines becaus开发者_StackOverflow中文版e /private/etc already exists along with files that I presumably need. If I run that last line, I'm afraid I'll overwrite any files located in that directory which I imagine would be disastrous.

Those links are http links. Open them in your favorite browser and you will see what will be pulled.

Those instructions are a bit strange, especially for /private. I would advise you to do the following: create a directory somewhere (/home/you/zsh-templates for instance), and run those commands in /home/you/zsh-templates/Library and .../private). You'll get the contents there.

Once you're sure that's what you need you can either repeat those in /Library and /private, or simply copy the files from your directory to their expected destination.
