Learning SQLite by watching Core Data?

I just finished my first simple Core Data Document Based Application. 
Four entities with multiple relationships.  Now I want to recreate the 
same thing using just SQLite.  I don't know SQLite, and I know very 
little Unix.  I had read it was possible to study SQLite using Core 
Data, but I am making no progress.  The closest I could get to opening 
my core data sqlite document with sqlite3 was to try mycoredatadoc > 
sqlite3 in the Terminal, but permission was denied.

Any suggestions?
