Bash plays a targeted yet critical role in DevOps: it’s commonly used for scripting one-off deployment steps, wrapping CLI tools, and creating lightweight tasks executed by CI runners or bootstrap scripts for virtual machines and containers. While configuration management tools and orchestrators handle complex state, Bash is perfect for quick orchestration, parsing command output, and gluing tools together. The key is to keep scripts idempotent, testable, and well-documented—avoid embedding secrets, validate inputs, and use environment variables responsibly. From a team perspective: establish conventions for reusable libraries, use shellcheck, and prefer small scripts invoked by higher-level orchestrators rather than monolithic shell programs to make debugging and change control easier.
