safe-bash-scripting

What problem does it solve?

This Bash scripting standard provides portable, safe, and maintainable guidelines to ensure scripts run reliably across macOS (Bash 3.2) and Linux, with consistent structures and safety patterns.

Core Features & Use Cases

• Shebang and strict options: enforce #!/usr/bin/env bash and set -euo pipefail for robust behavior.
• Portability and compatibility: avoid Bash 4+ features, rely on portable constructs and referencing the provided best-practices.
• Defensive programming: quoting, input validation, safe file operations, and trap-based cleanup to improve reliability in automation tasks.
• Use cases include local automation, CI tooling, build scripts, and deployment helpers requiring predictable shell behavior.

Quick Start

Start new Bash scripts by applying the Safe Bash standards: begin with a POSIX-friendly shebang and set -euo pipefail, avoid Bash 4+ features, quote all variables, and reference the provided templates and references.
