Version Control with Subversion - Basic Work Cycle - Examine Your Changes

Examine Your Changes

Once you've finished making changes, you need to commit them to the repository, but before you do so, it's usually a good idea to take a look at exactly what you've changed. By examining your changes before you commit, you can make a more accurate log message. You may also discover that you've inadvertently changed a file, and this gives you a chance to revert those changes before committing. Additionally, this is a good opportunity to review and scrutinize changes before publishing them. You can see exactly what changes you've made by using svn status , svn diff , and svn revert . You will usually use the first two commands to find out what files have changed in your working copy, and then perhaps the third to revert some (or all) of those changes.

Subversion has been optimized to help you with this task, and is able to do many things without communicating with the repository. In particular, your working copy contains a secret cached “pristine” copy of each version controlled file within the .svn area. Because of this, Subversion can quickly show you how your working files have changed, or even allow you to undo your changes without contacting the repository.
