Manage the cache

conda-exec caches environments for fast re-use. Over time, these caches can accumulate.

Tip

Run conda exec --list periodically to see how much disk space cached environments are using. Each unique combination of tool, version spec, and channels creates a separate cached environment.

List cached environments

conda exec --list

Shows all cached environments with their size, last-used timestamp, and package count.

Clean old caches

Remove environments not used in 30 days:

conda exec --clean

Preview what would be removed:

conda exec --clean --dry-run

Remove all caches:

conda exec --clean --all

Remove caches for a specific tool:

conda exec --clean ruff

Force re-creation

Note

The --refresh flag only affects the specific tool and spec combination you pass. Other cached environments are left untouched.

If a cached environment is stale or broken, force re-creation:

conda exec --refresh ruff check .
