ShellCheck is a GPLv3 static analysis tool that finds bugs, pitfalls, and style issues in bash/sh shell scripts. It runs from the terminal, integrates with editors and CI pipelines, and is also available as a web service.

Use cases

• lint bash scripts for syntax errors
• find quoting bugs in shell scripts
• check shell script portability between sh and bash
• integrate shell script checks into CI pipelines
• catch common beginner mistakes in shell scripts
• review shell scripts in my editor before committing

When to choose

• you write or maintain bash or POSIX shell scripts and want automated bug detection
• you want a linter for shell scripts in editors like Vim, Emacs, or VS Code
• you need to enforce shell script quality in CI or code review

When to avoid

• you need linting for languages other than shell scripts
• you require runtime or dynamic analysis rather than static checks
• you need a formatter that rewrites scripts rather than reporting issues
