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.
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.)
Additional links:
As mentioned in the other answers, the db-utils package (db4-utils under RHEL) has some tools. However, db_dump can be unhelpful, since the output is 'bytevalue' format.
For a quick'n'dirty viewer, use python:
me@machine$ python
Python 2.7.3 (default, Sep 26 2013, 20:03:06)
>>> import dbhash
>>> for k, v in dbhash.open( *<db filename here...>* ).iteritems(): print k, v
...
Note that dbhash is deprecated since python 2.6.
from bsddb3 import db
import collections
d = db.DB()
d.open('./file.dat', 'dbname', db.DB_BTREE, db.DB_THREAD | db.DB_RDONLY)
d.keys()
collections.OrderedDict((k, d[k]) for k in d.keys())
