Like any other piece of software (and information generally), cdb comes with NO WARRANTY. Things you have to decide before starting: Nothing. How to install: 1. Compile the programs: % make How to test: 2. Create a database from /etc/hosts: % ./12tocdbm < /etc/hosts | ./cdbmake test.cdb test.tmp 3. Test the database: % ./cdbtest < test.cdb found: 171 different record: 0 bad length: 0 not found: 0 too long to test: 0 The ``bad length'' and ``not found'' tallies should be 0. The ``different record'' tally should be 0 unless you have the same IP address listed on several lines in /etc/hosts. 4. Try retrieving particular records from the database: % ./cdbget 127.0.0.1 < test.cdb && echo '' localhost 5. Try printing some database statistics: % ./cdbstats < test.cdb slots 342 records 171 d0 157 d1 14 d2 0 d3 0 d4 0 d5 0 d6 0 d7 0 d8 0 d9 0 >9 0 That's it!
