svnadmin list-dblogs — Ask Berkeley DB which logfiles exist for a given Subversion repository
(applies only to repositories using the bdb backend).
Berkeley DB creates logs of all changes to the repository, which allow it to
recover in the face of catastrophe. Unless you enable
DB_LOG_AUTOREMOVE, the logfiles accumulate, although most
are no longer used and can be deleted to reclaim disk space. See 第 4.3 节 “管理磁盘空间” for more information.
