Omniscient is a gem that automatically dumps a MySQL database in a remote server via SSH, copies the dumped file to localhost via SCP and imports it, overwriting the local database (or table).
It'll be very useful for those that are developing using more than one machine and don't want to dump and clone data manually all the time.
In your console:
$ gem install omniscient
Then, type the following, where aliasname is a name you choose (i.e. home_computer, work etc):
$ omniscient clone aliasname
A setup will begin. The configuration will be saved to ~/.omni_config.yml.
Now that Omniscient knows where to connect, run the following command again:
$ omniscient clone aliasname
You can clone a 'custom_dbname' database from that host.
$ omniscient clone aliasname -d custom_dbname
Tested on Mac OS X.
