Polars CLI is now available!
polars-cli 0.1.0 was just released to crates.io.
Polars CLI provides a command line interface on top of the existing SQL functionality. You can use both interactively, and in a no-tty scenario! It serves as a command line tool to run SQL queries on json, parquet, arrow, and csv files using the polars query engine.
It is planned to eventually deploy this to popular package managers (brew, apt, yum, etc. However, it is only currently available through crates.io & cargo. cargo install polars-cli
