svnadmin list-dblogs — Ask Berkeley DB which log files exist for a given Subversion repository (applies only to repositories using the bdb backend).
svnadmin list-dblogs REPOS_PATH
Berkeley DB creates logs of all changes to the repository, which allow it to recover in the face of catastrophe. Unless you enable DB_LOGS_AUTOREMOVE, the log files accumulate, although most are no longer used and can be deleted to reclaim disk space. See the section called “Managing Disk Space” for more information.
