cmdfound is a single-file POSIX shell tool that resolves missing Linux commands by querying multiple package channels (GitHub releases, aqua, nix, pkgx, distro catalogs, containers) and running the best match on demand. It integrates with the shell to automatically intercept 'command not found' and provides route listing, cleanup, and ephemeral execution options, aiming to unify fragmented installation paths across Linux ecosystems.

Target audience: linux users, devops engineers, backend developers, power users
