conda list is a core command in the Conda package manager, used to display all packages installed in the currently active environment or a specified one. Each entry shows the package name, version, build string, and source channel. It helps users inspect dependencies, verify installations, and debug issues. By default, packages are listed in installation order from oldest to newest, but options allow sorting, filtering, and alternative formats like JSON or exportable YAML. A regex pattern can filter results to specific packages. This command is vital for reproducible science, enabling environment sharing via exports. It integrates with Anaconda/Miniconda ecosystems, supporting Python, R, and other languages. Output includes build details for precise recreation. Use with --name or --prefix to target non-active environments without switching.

Requires active conda environment; output varies by conda version. Regex pattern is case-sensitive. Does not list unpinned packages distinctly without options.

conda list # All packages
conda list numpy # Filter numpy
conda list --export > environment.yml # Export spec

Name | Version | Build | Channel
e.g., numpy 1.21.0 py39hblah_0 conda-forge

Developed as part of Conda (2012) by Anaconda Inc. for managing complex dependencies. Gained --export and --revisions in Conda 4.4+ (2017); JSON support in later 4.x releases. Widely used in data science for reproducible workflows.
