ShellCheck

ShellCheck is a static analysis tool tailored for shell scripts, designed to enhance code quality through effective linting and error detection. It identifies common mistakes such as syntax errors, typos, and incorrect command usage, helping users catch issues early and improve the reliability of their scripts. By providing clear explanations and suggestions for best practices, ShellCheck not only aids in correcting errors but also teaches good coding habits. It supports various shells, including Bash, sh, and dash, and can be easily integrated into different development environments, whether used online, within code editors, or through command-line interfaces. As an open-source tool, ShellCheck benefits from a vibrant community of contributors, although it is specifically focused on shell scripts and may not catch every possible issue. Some users might find its suggestions to be somewhat opinionated, but overall, ShellCheck remains a valuable resource for anyone looking to enhance their shell scripting skills.
