Preface

In agent development and system operations scenarios, Bash scripts are often used to execute low-level tasks. If a script lacks standardized error handling and parameter validation, undefined variables, pipeline errors, or malicious input may cause the script to exit unexpectedly, or even lead to security issues. This article introduces a DSH plugin designed to standardize Bash script development and provide defensive patterns.

Plugin Positioning

The plugin provides the following core features:
* Bash script defensive mode: Establishes defensive standards for script development.
