[sqlite] How initialize a database file from unix shell without landing in SQLite command prompt?

[Mikael]

I have a file DBDEFINITION.TXT that I want to use to initialize [execute
on] the database DB.SQLITE.

How do I do something like

$ sqlite3 -exec DBDEFINITION.TXT DB.SQLITE
$


?

All methods I tried end me up in the SQLite prompt, and that is what I
don't want. Like, doing sqlite3 -init DBDEFINITION.TXT DB.SQLITE and having
".quit" as last line in the definition file.

Thanks.
