What problem does it solve?

Set up or review ShellCheck usage for Bash and POSIX shell projects, including linting scope, CI integration, and practical rule handling. Use when improving shell script quality gates or explaining lint findings.

Core Features & Use Cases

Use ShellCheck as the default guardrail for shell correctness and safety.
Keep suppressions narrow, justified, and visible.
Match linting mode to the intended shell, such as Bash or POSIX sh.
Integrate linting into local workflows and CI without creating noisy false positives.
Pair linting with formatting and targeted script tests where practical.

Quick Start

Start by enabling ShellCheck configuration in your repository to scan scripts and establish a baseline in local and CI workflows.

FAQPage Schema

How do I integrate ShellCheck linting into a CI pipeline for Bash scripts?▼

Integrate ShellCheck linting into CI pipelines by configuring the linting scope and shell mode to validate Bash scripts automatically. This establishes baseline shell script correctness and safety checks across automated workflows without generating noisy false positives.

What is the best way to suppress ShellCheck warnings in POSIX sh projects?▼

The best way to suppress ShellCheck warnings is to keep suppressions narrow, justified, and visible. This approach maintains POSIX sh project quality gates while ensuring ignored lint findings remain transparent for code review triage.

Does ShellCheck work with both Bash and POSIX sh shell modes?▼

Yes, ShellCheck works with both Bash and POSIX sh by matching the linting mode to the intended shell. Configuring the correct shell mode ensures the linter applies the appropriate syntax and correctness validation rules for the specific script environment.

How do I configure ShellCheck to avoid noisy false positives in local development?▼

Configure ShellCheck to avoid noisy false positives by defining a precise linting scope and applying narrow suppressions for specific rules. This keeps local development workflows focused on genuine shell script correctness issues rather than irrelevant warnings.

Why should I pair ShellCheck linting with formatting and script tests?▼

Pairing ShellCheck linting with formatting and targeted script tests provides comprehensive shell script validation. While linting enforces correctness and safety rules, formatting and tests verify runtime behavior and style consistency where practical for robust quality gates.
