Shellcheck features and specs

• Static Code Analysis
  ShellCheck provides static analysis for shell scripts, allowing developers to catch errors and potential bugs without executing the script.
• Comprehensive Error Detection
  It identifies a broad range of issues, including syntax errors, semantic errors, and best practice violations, helping to improve script reliability.
• Suggestions for Improvements
  ShellCheck offers suggestions and fixes for many issues it detects, assisting developers in adhering to best practices.
• Wide Compatibility
  ShellCheck supports various shell dialects, including Bash, Dash, and others, making it versatile for different environments.
• Open Source
  Being open-source, ShellCheck is freely available to everyone, with a community that contributes to its improvement and updates.
• Integration with Editors
  ShellCheck integrates with various text editors and IDEs, enabling seamless error checking within the developer's workflow.

Possible disadvantages of Shellcheck

• Learning Curve
  Users may need time to learn and understand ShellCheck's feedback, especially if they are not familiar with shell scripting best practices.
• Potential Overhead
  While it provides valuable insights, using ShellCheck can add an overhead to the development process as scripts need to be checked and errors reviewed.
• Not a Substitute for Testing
  ShellCheck should not be considered a substitute for thorough testing. Scripts still need to be executed to ensure functional correctness.
• False Positives
  Like many static analyzers, ShellCheck may generate false positives, which can be misleading and require manual verification by the developer.
• Resource Intensive for Large Scripts
  Analyzing very large or complex scripts might consume significant resources, potentially slowing down the workflow on older machines.

Possible disadvantages of Yetus

• Complex Setup
  Yetus can have a steep learning curve, and setting it up may be more complex compared to some other tools that offer similar functionalities.
• Limited Documentation
  The documentation may not be as exhaustive or user-friendly, potentially making it challenging for new users to fully leverage the tool's capabilities.
• Niche Usage
  Yetus is focused more on certain use cases related to the Apache ecosystem, which might limit its broader appeal to developers outside this community.
• Performance Overhead
  Running extensive precommit checks can introduce a performance overhead, which might slow down the development process if not managed properly.
