ShellCheck Vidar Holen

ShellCheck is a tool designed to analyze bash and sh shell scripts, providing warnings and suggestions to improve their quality and reliability. By scanning scripts for common pitfalls, syntax issues, and best practices violations, ShellCheck helps developers write more robust and portable code.

Key Features:

• Script Analysis: Examines the structure of your script to detect potential bugs, inefficiencies, and non-portable constructs.
• Portability Warnings: Highlights issues that may cause scripts to behave differently across various shells or operating systems.
• Quoting Detection: Identifies problematic quoting practices that can lead to unexpected behavior or security vulnerabilities.
• File Type Handling: Warns about incorrect handling of file types, such as improperly processing compressed files (e.g., .gz, .zip).
• Static Analysis: Performs semantic checks to detect higher-level issues, such as incorrect logic in conditional statements.

Audience & Benefit:

Ideal for developers, DevOps engineers, and anyone writing shell scripts. By identifying potential errors early, ShellCheck helps reduce debugging time, improve code quality, and ensure scripts are portable across different environments. This tool is particularly useful for maintaining reliable and maintainable shell scripts in both individual projects and team workflows.

ShellCheck can be installed via winget, making it easily accessible for developers to integrate into their workflow.
