   .dump [--schema-only|--data-only] <table_name>   # Render database structure as SQL
   .databases			                 # List all databases
   .use <database_name>		                 # Switch to a database by name
   .dbinfo				                 # Get information about the current database
   .read <file_name>		                 # Load and execute SQL statements from a file
   .create <database_name>		                 # Create a new database
   .destroy <database_name>	                 #  Destroy a database by name
   .output stdout|file_path                         # Set the output to stdout or file
