Bash Hygiene

Practical Bash scripting hygiene for script structure, strict mode, quoting safety, and portability verification.

When to use

• Creating or editing Bash scripts in bin/, scripts/, or hooks.
• Reviewing shell scripts for reliability and maintainability.
• Debugging failures caused by word splitting, globbing, or shell incompatibility.
• Standardizing shell quality gates in CI.

Philosophy

• Make interpreter intent explicit before writing logic.
• Prefer correctness and clarity over shell cleverness.
• Treat quoting and portability as baseline quality, not optional polish.
