Bash to Rust: From Zero is a hands-on conversion course for engineers, sysadmins, and data engineers who already write shell scripts and want to graduate to Rust for production-grade automation. You will learn how to translate common Bash idioms (pipes, redirects, glob expansion, process substitution, exit codes, signal handling, environment variables) into idiomatic Rust using crates like std::process::Command, clap for argument parsing, anyhow and thiserror for error handling, and tokio for async I/O. The course walks through real migration scenarios: replacing fragile shell pipelines with reliable Rust CLIs, building cross-platform automation that no longer depends on coreutils versions, packaging a single static binary for distribution, and structuring projects so that they can be tested, profiled, and maintained by a team. You will also learn when to keep using Bash (one-off glue) and when to invest in Rust (anything that gets re-run, shared, or shipped to production). By the end of the course, you will be able to migrate a non-trivial shell script to Rust, replace it in production, and reason about correctness, performance, and portability trade-offs.
