What is the 'unofficial bash strict mode'?

It uses 'set -Eeuo pipefail' to ensure scripts exit immediately on errors, unset variables, or pipe failures, catching bugs early in execution.

Is this skill suitable for CI/CD pipelines?

Yes, it focuses on creating reliable, idempotent, and error-aware scripts specifically designed for production environments like GitHub Actions, Jenkins, or GitLab CI.

Why should I quote all variables in Bash?

Quoting variables like "$var" prevents word splitting and globbing, which are common sources of logic bugs and security vulnerabilities in shell scripts.

How does this skill handle script cleanup?

It implements 'trap' commands to ensure temporary files and background processes are cleaned up even if the script fails or is interrupted by the user.

Does this skill support dry-run functionality?

Yes, it includes patterns for implementing a --dry-run flag, allowing users to preview changes before they are actually executed on the system.
