Path Filter (Trigger) - CI/CD Glossary Definition

A path filter runs a workflow only when the commit touches files matching a glob pattern.

A path filter uses paths or paths-ignore on a push or pull_request trigger so a workflow only runs when the changed files match the given patterns.

Path filters cut wasted runs in monorepos by skipping jobs when nothing relevant changed; paths-ignore does the inverse, skipping runs for irrelevant paths like docs.
