bash-script-validator

To check bash scripts for syntax errors and security vulnerabilities, use a validation tool that runs `bash -n` and integrates ShellCheck static analysis. This automatically identifies command injection risks, unsafe `eval`, and dangerous `rm -rf` usage while detecting script inefficiencies.

The best way to lint shell scripts for best practices is applying static analysis rules that detect performance issues and bashisms. Using ShellCheck integration provides comprehensive analysis with detailed error codes, ensuring your scripts are robust and follow POSIX sh portability standards.

Yes, you can validate POSIX sh scripts to detect bashisms before deployment by using a validator that automatically detects the shell type from the shebang. It applies appropriate validation rules using `sh -n` and ShellCheck to ensure portability across different shell environments.

To debug shell script problems related to command injection, run a security audit using static analysis. This identifies potential command injection vulnerabilities, flags unsafe `eval` usage, and highlights dangerous `rm -rf` commands, allowing you to fix security issues before they cause problems.

Yes, the shell script validator works with both .sh and .bash files. It automatically detects the shell type from the shebang in your script files and applies the appropriate validation rules, checking syntax, security vulnerabilities, and performance optimizations regardless of the specific shell extension.
