Some time ago I wrote pq (https://github.com/prql/prql-query) which aimed to be a simple CLI for PRQL to wrangle data on the command line, much like sq. Unfortunately I haven't had time to maintain it so it is now archived and out of date. I hope that I might get a chance to update it again. More has happened since then and there are low hanging fruit to make it more usable, for example adding connector_arrow (https://github.com/aljazerzen/connector_arrow) support for other databases, etc... Quick example of how things looked with pq: ```sh
$ pq --from i=invoices.csv "from i | take 5"
+------------+-------------+-------------------------------+-------------------------+--------------+---------------+-----------------+---------------------+-------+
| invoice_id | customer_id | invoice_date | billing_address | billing_city | billing_state | billing_country | billing_postal_code | total |
+------------+-------------+-------------------------------+-------------------------+--------------+---------------+-----------------+---------------------+-------+

$ # When there is only one input table then this automatically becomes the source relation, i.e. `from i | ` is prepended to the query
$ # so this can be simplified to:
$ pq --from invoices.csv "take 5"
...
```
