Here is what I see. I don't quite understand where `dirOnly` and `dir`are defined. <https://sqlite.org/cli.html> writefile() only has two arguments according to the above page. Why does it have 4 arguments below `($dir || name)`, `sqlar_uncompress(data, sz)`, `mode`, `mtime`? Why does the same select command appear twice below? What does `name NOT GLOB '*..[/\]*'` mean? So things like `abc../` is ignored? This does not make sense to me. ``` $ sqlite3 -Axfn my.db -- open database 'my.db' SELECT ($dir || name), writefile(($dir || name), sqlar_uncompress(data, sz), mode, mtime) FROM sqlar WHERE (1) AND (data IS NULL OR $dirOnly = 0) AND name NOT GLOB '*..[/\]*' SELECT ($dir || name), writefile(($dir || name), sqlar_uncompress(data, sz), mode, mtime) FROM sqlar WHERE (1) AND (data IS NULL OR $dirOnly = 0) AND name NOT GLOB '*..[/\]*' ```
