Why should I use ShellCheck for my scripts?

It catches common but dangerous errors such as improper quoting, word splitting, unhandled exit codes, and syntax that may behave differently across different shell versions.

ShellCheck is a static analysis tool that detects bugs, potential issues, and non-portable patterns in shell scripts including Bash, sh, dash, and ksh.

Can this skill help with CI/CD integration?

Yes, it provides configuration snippets and workflow examples for integrating ShellCheck into GitHub Actions, GitLab CI, and custom shell-based pipelines.

Does this skill support shells other than Bash?

Yes, it covers configuration for various shell dialects and provides specific guidance on maintaining POSIX compliance for maximum script portability.

How do I disable a specific ShellCheck warning?

You can suppress specific rules by adding a directive like '# shellcheck disable=SCxxxx' on the line above the code or at the beginning of the script for global exclusion.
