What problem does it solve?

ShellCheck configuration guidance helps you lint shell scripts consistently, prevent common portability and quoting bugs, and make CI failures actionable instead of noisy.

Core Features & Use Cases

• ShellCheck setup and installation: Install ShellCheck via common package managers or from source, then verify it in your environment.
• Project-level configuration: Use a .shellcheckrc to set the target shell, enable optional checks, and disable known-noisy rules such as SC1091.
• Practical remediation workflow: Learn common warnings and fixes (quoting issues, exit-code checks, POSIX compliance) and apply targeted suppressions when false positives occur.
• CI/CD integration patterns: Run ShellCheck across changed or all .sh files with formats suited for logs, GCC-style output, or parsing.

Quick Start

Create a .shellcheckrc in your project root with your target shell set to bash, then run ShellCheck with CI-style GCC output to catch issues early.
