11Usage: rudb [OPTIONS] [FILENAME [SQL...]]
12
13An embedded analytical database, compatible with DuckDB.
14
15FILENAME is the database to open. Only :memory: works today, because there is no storage format
16yet. A second argument is SQL to run, after which the shell exits.
17
18Options:
19  -bail                  stop after the first error
20  -batch                 read input as a script even when it is a terminal
21  -c, -s SQL             run SQL and exit
22  -cmd SQL               run SQL before reading input, and keep reading
23  -echo                  print each statement before running it
24  -f, -file FILENAME     run a file of SQL and exit
25  -header, -noheader     turn column names on or off
26  -init FILENAME         run a file of SQL before reading input
27  -interactive           show a prompt even when input is not a terminal
28  -newline SEP           what goes between rows in the separated modes
29  -nullvalue TEXT        what a null prints as
30  -readonly              open without allowing writes
31  -separator SEP         what goes between values in the separated modes
32  -version               print the version and exit
33  --print-config         print the build configuration and exit
34  -h, -help              print this and exit
35
36Any mode can also be given as an option, so -csv is the same as -cmd '.mode csv'.
