Documentation: - https://sqlite-utils.datasette.io/en/latest/cli.html#returning-raw-data-such-as-binary-content - https://sqlite-utils.datasette.io/en/latest/cli-reference.html#query - https://sqlite-utils.datasette.io/en/latest/cli-reference.html#memory

bash sqlite-utils memory /tmp/books3.json:nl \ 'select name from books3' --raw-lines > titles.txt

I'm tempted to upgrade --raw to do this instead, but that would be a breaking change.
