The shell is an interactive tool in which you can
- Experiment with Angle queries
- Explore the data in a Glean database
- Experiment with schema changes and derived predicates
- Create experimental databases and query them
glean shell --service HOST:PORT
to connect to a server, or
glean shell --db-root DIR
to use local databases from directory
See shell options for more command-line options.
- List the available databases with

:index LANGUAGE DIR

Show schema for the given
TYPE, or the whole schema if no predicate or type is given.
Edit a query in an external editor. Set the
