How do I disable specific ShellCheck rules?

You can disable rules globally by adding 'disable=SCxxxx' to your .shellcheckrc file, or locally within a script using the '# shellcheck disable=SCxxxx' comment above the specific line.

How do I handle scripts that source external files?

You can use the 'external-sources=true' setting in your configuration or use the '# shellcheck source=path/to/file' directive to help ShellCheck track variables and functions across files.

Does this skill help with POSIX compliance?

Yes, it provides specific guidance on using the --shell=sh flag and interpreting SC3000-series warnings to identify non-portable bashisms.

Is it possible to automate ShellCheck in GitHub Actions?

Yes, the skill provides ready-to-use YAML configurations for GitHub Actions to ensure every push or pull request meets your quality standards.

Can ShellCheck be integrated into Git workflows?

Absolutely. This skill includes patterns for setting up pre-commit hooks that automatically run ShellCheck on staged files before a commit is finalized.
