Hi. Released a script recently to sync the contents of tables between two different mysql databases.
The need for this is mostly as a faster, open source replacement to
Navicat [to those who have used it] or SQLyog -- since you can sync on
the command line it's faster
Syntax: ruby syncer.rb --from=database1 --to=database2 --tables=table_1,table_2
It will show you a diff of the tables and/or optionally sync them so that the contents of database2's table_1 and table_2 will match database1
New in version 0.2: Now it can do a limited structure sync of different tables, as well, and perform an "entire database" sync.
See http://code.google.com/p/ruby-roger-useful-functions/wiki/MysqlTableSyncer for more details.
Feedback welcome. Thanks! -=Roger
