What is ShellCheck and why should I use it?

ShellCheck is a static analysis tool that identifies bugs, security vulnerabilities, and portability issues in shell scripts. Using it prevents common runtime errors and ensures your scripts follow best practices.

How do I ignore specific ShellCheck warnings?

You can suppress warnings by adding a comment like '# shellcheck disable=SCxxxx' above the specific line or at the beginning of the script to disable it globally.

Can I integrate ShellCheck into my CI/CD workflow?

Yes, this skill provides specific configurations for GitHub Actions, GitLab CI, and pre-commit hooks to automatically lint your scripts on every push or pull request.

Does this skill help with script portability?

Absolutely. It includes instructions on how to use the --shell flag to ensure your scripts are compatible with specific shells like POSIX sh or Dash.
