When working on a project with a team, you’ll want to update your working copy to receive any changes other developers on the project have made since your last update. 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, it appears that someone checked in modifications to both foo.c and bar.c 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 tell you which actions Subversion performed to bring your
working copy up to date. To learn what these letters mean, run
svn help update.
