DuckDB Shellfs Extension

The shellfs extension for DuckDB enables the use of Unix pipes for input and output. By appending a pipe character | to a filename, DuckDB will treat it as a series of commands to execute and capture the output. Conversely, if you prefix a filename with |, DuckDB will treat it as an output pipe.

Documentation

Full documentation, including installation, usage, the function reference, and cookbook examples, is available at:

https://query.farm/products/extensions/shellfs

Installation

install shellfs from community;
load shellfs;

Development

For instructions on building the extension from source and running its tests, see BUILDING.md.
