Cache

postmortem cache

Manage the on-disk cache that backs the networked paths (tree --online, --vulns, and system --online).

postmortem cache <action>

Where it lives

~/.postmortem/cache/, as one JSON file per entry, grouped by namespace:

Namespace	Contents
registry/	package → source-repo resolution (immutable per name@version).
repo/	source-repo stats, keyed by host/owner/repo.
languages/	repo language breakdowns (--languages).
npm-meta/	npm packument provenance (per name@version).

Because a published version's metadata never changes, resolutions are cached indefinitely; re-runs are near-instant. Each entry records when it was fetched.

prune

Remove cached entries. With no filter it prunes everything.

postmortem cache prune                    # remove all cached entries
postmortem cache prune --older-than 30    # keep entries fetched in the last 30 days
postmortem cache prune --dry-run          # report what would be removed, delete nothing

Flag	Description
--older-than <DAYS>	Only remove entries older than N days (by file mtime).
--dry-run	Show what would be removed without deleting.

The report gives the number of entries removed/kept, bytes freed, and the cache path.
