svn update
Once you have a checked out copy, this is called a working copy. To update a working copy to the latest version, you use the update command with no arguments:
- svn update
If you want to update to a specific revision, you can add the -r <revision> option to move to any revision of the code within the working copy that you checked out. Note that if you checked out a branch, you will be changing to the revision within that branch.
- svn update -r 123
