Worked on stabilizing the touch command in the uutils/coreutils repository, focusing on handling dangling symlink references with the -r and --reference options. Addressed a bug where referencing a dangling symlink led to inconsistent behavior across Windows and Unix, implementing a Rust-based solution that ensures the command fails gracefully and provides clear error messaging. Expanded and refined the test suite to cover these edge cases, using test-driven development and adapting tests for cross-platform differences. This work improved the reliability of coreutils in production pipelines, reduced user confusion, and demonstrated skills in Rust, system programming, and cross-platform testing.
