The command line tool sqlite3 can be used to view the content of a database. One way of using it is typing in "sqlite3 FILE" and the database contained in FILE is opened for query commands.
The command line tool sqlite3 can also be used to perform a query directly. For example, typing "sqlite3 FILE 'select * from Table1'" will print out all contents in table Table1. This is handy for showing large tables, because we can pipe the output into a reader tool. "sqlite3 FILE 'select * from Table1' | more".
