sqlite3 is a terminal-based front-end to the SQLite
  library that can evaluate queries interactively and display the results in
  multiple formats. sqlite3 can also be used within
  shell scripts and other applications to provide batch processing features.
To start a sqlite3 interactive session,
    invoke the sqlite3 command and optionally provide
    the name of a database file. If the database file does not exist, it will be
    created. If the database file does exist, it will be opened.
For example, to create a new database file named "mydata.db", create a table named "memos" and insert a couple of records into that table:
$ sqlite3 mydata.db
SQLite version 3.1.3
Enter ".help" for instructions
sqlite> create table memos(text, priority INTEGER);
sqlite> insert into memos values('deliver project description', 10);
sqlite> insert into memos values('lunch with Christine', 100);
sqlite> select * from memos;
deliver project description|10
lunch with Christine|100
sqlite>
If no database name is supplied, the ATTACH sql command can be used to attach to existing or create new database files. ATTACH can also be used to attach to multiple databases within the same interactive session. This is useful for migrating data between databases, possibly changing the schema along the way.
Optionally, a SQL statement or set of SQL statements can be supplied as a single argument. Multiple statements should be separated by semi-colons.
For example:
$ sqlite3 -line mydata.db 'select * from memos where priority > 20;'
    text = lunch with Christine
    priority = 100
A list of available meta-commands can be viewed at any time by issuing the '.help' command. For example:

sqlite3 has the following options:
-init
    file-echo-header-noheader-column-html-line-list-separator
    separator-nullvalue
    stringNULL values. Default is “\” (empty
      string).-version-helpsqlite3 reads an initialization file to set the
  configuration of the interactive environment. Throughout initialization, any
  previously specified setting can be overridden. The sequence of initialization
  is as follows:
mode            = LIST
separator       = "|"
main prompt     = "sqlite> "
continue prompt = "   ...> "
    
    -init option is present, the specified file
      is processed.| December 16, 2012 | NetBSD 9.4 |
