A simple script that splits a MySQL dump into lots of smaller files.

First you need a mysqldump file, put it into the directory you want all the split files in:

$ ruby split-mysql-dump.rb db.sql
Found a new db: app
Found a new table: administrator_log
    writing line: 229 200.494MB in 4 seconds 50.124MB/sec

    Found a new table: auth_strings
        writing line: 239 205.482MB in 6 seconds 34.247MB/sec

Alternatively, you can pipe in via STDIN in using '-'. Great for working with large gzipped backups:

$ gunzip -c db.sql.gz | ruby split-mysql-dump.rb -

When you're done you should have lots of files like this:

-rw-r--r-- 1 rip rip   210233252 May 17 18:06 app_administrator_log.sql
-rw-r--r-- 1 rip rip   215463582 May 17 18:06 app_auth_strings.sql

The first bit of the files will be the database that the tables are in based on the USE statements in the dump.
