SVN create and switch to branch

Mac OS X 10.8.2

svn, version 1.6.18 (r1303927)

I want to work a new svn branch. And try the following comment

svn copy svn://server/path/trunk/project_name svn://server/path/branches/new_branch

But it's not ok. It returns error message:

"svn: Could not use external editor to fetch log message; consider setting the $SVN_EDITOR environment variable or using the --message (-m) or --file (-F) options

svn: None of the environment variables SVN_EDITOR, VISUAL or EDITOR are set, and no 'editor-cmd' run-time configuration option was found"

The command MUST have comment message like this

svn copy svn://server/path/trunk/project_name svn://server/path/branches/new_branch -m "create new branch"

The result is the project is copy to 

svn://server/path/branches/new_branch/project_name

The we can go to the working copy and switch to the new branch by

 svn switch svn://server/path/branches/new_branch/project_name

Everything is ok. You modification to the old working copy is still there.



The --relocate option of switch causes svn switch to do something different: it updates your working copy to point to the same repository directory, only at a different URL (typically because an administrator has moved the repository to another server, or to another URL on the same server).[1]
