SVN在Mercurial中是否具有“hg clone”或Git中的“git clone”？

Question

I have a URL for a Subversion repository and on the command line on Ubuntu I want to just download a copy of the repository as you would do in Mercurial by typing:

hg clone http://svn.somerepository.com/somerepository/trunk/docs/

1. How do you "clone" a repository in SVN?

2. Also, I just want to get everything below the docs folder - I don't want to start in the trunk - how would you do something like this:

   svn clone http://svn.somerepository.com/somerepository/trunk /docs/

Answer 1

You want to perform what in SVN-land is called a "check out."

svn co http://svn.somerepository.com/somerepository/trunk/docs/

Note the main difference between SVN and distributed systems like Mercurial or Git is that SVN's "check out" command downloads only a copy of the most recent version of each file, whereas with hg clone you will actually end up with a local copy of the repository's entire history as well. This has some implications for the way in which you work. For example, you need to have a network connection to the server in order to retrieve logs, perform diffs, etc.

Answer 2

If you just need to grab the current version, svn checkout is all you need.

If you want a complete copy of the repository, including all previous versions, you can use svnsync . It can copy a complete repository and incrementally download new commits. I don't think it can be restricted to subdirectories though.

Answer 3

1. You can't clone the repository without having admin access to it (ie the ability to do svnadmin commands).
2. You can certainly check out the subtree with svn co http://....../docs

Answer 4

svn co svn://www.example.com/path/to/repository/...

其中“co”是“结账”的缩写。
