This article provides a detailed tutorial on using AWK to count only the implementation lines in a Rust codebase, ignoring test code written in the same files. It explains the problem with standard tools like `wc` or `tokei`, presents a step-by-step AWK solution with code examples, and discusses common pitfalls like incorrectly using the `exit` statement.
