What is the purpose of a .shellcheckrc file?

A .shellcheckrc file is a project-level configuration that allows you to define global rules, enable optional checks, and set the target shell for all scripts in a repository.

How do I disable a specific ShellCheck warning?

You can use a comment directive like '# shellcheck disable=SCxxxx' on the line before the issue or at the top of the script to disable it for the entire file.

How do I integrate ShellCheck into a GitHub Actions workflow?

You can use the 'actions/checkout' step followed by a run command that uses 'apt-get install shellcheck' or the official ShellCheck docker image to analyze your .sh files.

Can I use ShellCheck for shells other than Bash?

Yes, ShellCheck supports sh, dash, ksh, and other POSIX-compliant shells. You can specify the shell via the shebang line or the --shell flag.

Why does ShellCheck warn about unquoted variables?

Unquoted variables (SC2086) can lead to word splitting and globbing, which often causes scripts to break when filenames contain spaces or special characters.
