How do I create a Bash script that works on both macOS and Linux?▼

Creating a portable Bash script requires Bash 3.2-compatible defaults and proper quoting. This generator automates that scaffolding, ensuring your shell utilities run safely across macOS and Linux environments with minimal friction.

What is the safest way to start a Bash script for production use?▼

Starting a Bash script safely requires enforcing set -euo pipefail, proper quoting, and argument validation. This generator applies these organizational constraints automatically to provide a standardized guardrail scaffold for robust shell utilities.

How do I add a guardrail to check requirements before running a shell script?▼

Adding a guardrail involves implementing a check_requirements function to validate arguments, env vars, and required tools before execution. This generator includes this guarded execution function to provide friendly error messages when validations fail.

Does this Bash script generator support POSIX-compliant scripting standards?▼

Yes, this Bash script generator supports POSIX scripting standards by applying portable defaults and Bash 3.2 compatibility. It ensures your scripts adhere to strict quoting and safety standards required for cross-platform portability.

Why does my Bash script fail on macOS when using associative arrays?▼

Your Bash script fails on macOS because the system ships with Bash 3.2, which lacks associative arrays. This generator scaffolds Bash 3.2-compatible scripts with portable defaults, avoiding modern syntax that breaks on older shell versions.
