When working on a project with a team, you'll want to update your working copy to receive any changes made since your last update by other developers on the project. Use svn update to bring your working copy into sync with the latest revision in the repository.
$ svn update U foo.c U bar.c Updated to revision 2.
In this case, someone else checked in modifications to
since the last time you updated, and Subversion has updated
your working copy to include those changes.
When the server sends changes to your working copy via svn update, a letter code is displayed next to each item to let you know what actions Subversion performed to bring your working copy up-to-date. To find out what these letters mean, see svn update.
