# Standard In

Quine fully supports reading from Standard In. Together with writing @ref:[Standing Queries to Standard Out](../standing-query-outputs.md), Quine is a powerful tool for any command-line data processing task.

The following is a simple @ref[Recipe](../../core-concepts/about-recipes.md) that ingests each line of input from Standard In as a node in the graph. It also uses a Standing Query to write every to Standard Out:

@@snip [pipe.yaml]($quine$/recipes/pipe.yaml)

To run this Recipe, pipe data from other program into Quine. This example uses the Unix `find` program as a data source:

```
❯ find /dev | java -jar quine.jar -r pipe
Graph is ready
