This one has bugged me for a long time. During a project where things get passed from developer to developer or designer to designer things often get renamed to the same name, only with a different case. For example, myFlv_IN.flv becomes myFlv_in.flv. I used to think you had to move the files away, rename them, and then re-add them. Turns out if you simply include the full path to the repository it’ll do the rename in place for you.
For example:
svn mv -m 'rename' http://my.repository.com/myFlv_IN.flv http://my.repository.com/myFlv_in.flv
More details can be found here, at the Subversion FAQ.
