I\'m using Subversion 1.5 and have a single file in a branch that I want to merge into another branch. When I do a svn merge http://path/to/file I get an error,
svn merge http://path/to/file
Try specifying the path to the local file as well.
For example,
svn merge -r1234:1235 svn://your_svn_url/to/file ./local_file
