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 the section called “Managing Disk Space” for more
information.
