What SVN command can I use to see the branch I'm currently using?

I generally use Subclipse, but there's some wonkiness in my code right now and I want to do some sanity checks from the command line. Thanks to Subclipse, I can usually see the branches I'm using in Eclipse's Package Explorer window.

What command can I use from the command line to see the branch I'm currently using?

Resources I tried before Stack Overflow include the SVN book, this list of commands and this other list of commands. I didn't find anything that would let me passively look at branch information (as opposed to making some sort of active branch modification, which is not what I want).

Try the following:

svn info

This will give you the URL your workspace is a checkout of, relative to where you are in the workspace. You should be able to see the branch in the URL.

With some regex, you can get just the branch name:

svn info | grep '^URL:' | egrep -o '(tags|branches)/[^/]+|trunk' | egrep -o '[^/]+$'

'svn info' from https://edoras.sdsu.edu/doc/svn-book-html-chunk/svn.ref.svn.c.info.html

The branch is what shows up in the URL below:

$ svn info foo.c
Path: foo.c
Name: foo.c
URL: http://svn.red-bean.com/repos/test/foo.c
Repository Root: http://svn.red-bean.com/repos/test

svn info will tell you the origin of your working copy. From that you can tell the branch.
