# Description

This command shows the output attributes provided by the flake
specified by flake reference *flake-url*. These are the top-level
attributes in the `outputs` of the flake, as well as lower-level
attributes for some standard outputs (e.g. `packages` or `checks`).

With `--json`, the output is in a JSON representation suitable for automatic
processing by other tools.

Title: Viewing Flake Output Attributes with Examples
Summary
This document describes a command used to display the output attributes of a specified flake. It provides an example using the `patchelf` flake, illustrating how it categorizes attributes like `checks`, `packages`, `hydraJobs`, and `overlay` across different architectures (aarch64-linux, i686-linux, x86_64-linux). The command shows top-level attributes from the flake's `outputs` and lower-level standard outputs. An option to format the output as JSON for automatic processing is also mentioned.
