The CLI help currently reads as if only one SQL query/dot command can be provided:

$ sqlite3 -help
Usage: sqlite3 [OPTIONS] [FILENAME [SQL]]

For SQL, one can separate multiple queries with semicolons; this does not work for dot commands though (based on testing). It is possible though to just provide multiple strings.

Example:

$ sqlite3 :memory: 'SELECT 42'
42

$ sqlite3 :memory: 'SELECT 42; SELECT 43'
42
43

$ sqlite3 :memory: '.mode json; SELECT 42; SELECT 43;'
extra argument: "42;"

$ sqlite3 :memory: '.mode json' 'SELECT 42; SELECT 43;'
[{"42":42}]
[{"43":43}]

Thus, it would be nice if the help output could be adjusted to e.g. (as for vim -h)

Usage: sqlite3 [OPTIONS] [FILENAME [SQL ...]]

Usage: sqlite3 [OPTIONS] [FILENAME [SQL]...]
