I have a set of Berkeley DB files on my Linux file system that I'd like to examine.
What useful tools exist for getting a quick overview of the contents? I can write Perl scripts that use BDB modules for examining them, but I'm looking for some CLI utility to be able to take a look inside without having to start writing scripts.

Use the db_dump program. It is contained in the package core/db (Arch), db-util (Debian, Ubuntu), sys-libs/db (Gentoo, note that here the binary is called db4. 8_dump or whatever version you are using). On some systems the man pages are not installed, in that case the documentation can be found here.
The db_dump utility reads the database file file and writes it to the standard output using a portable flat-text format understood by the db_load utility. The file argument must be a file produced using the Berkeley DB library functions.
Use the db_dump program. It is contained in the package core/db (Arch), db-util (Debian, Ubuntu), sys-libs/db (Gentoo, note that here the binary is called db4.8_dump or whatever version you are using).
On some systems the man pages are not installed, in that case the documentation can be found here. By default, db_dump outputs some hex numbers, which is not really useful if you are trying to analyse the content of a database. Use the -p argument to change this.
Show everything that’s in the file database.db:
db_dump -p database.db List the databases in the file database.db:
db_dump -l database.db Show only the content of the database mydb in the file database.db:
db_dump -p -s mydb database.db Check out the db-utils package. If you use apt, you can install it with the following: apt-get install db-util (or apt-get install db4.8-util or whatever version you have or prefer.)
