How it works

Match one optional wildcard capture, substitute it into the destination and remove refs matching any negative pattern.

The example maps refs/heads/main to refs/remotes/origin/main and excludes refs/heads/tmp/work.

Limits

Named refs and HEAD only; no object-ID or shorthand expansion. Force flags are displayed, not applied. Nothing is fetched, updated or pruned.

Utility
