Shellharden
Shellharden is a shell script hardening tool and linter designed to improve the security and reliability of Bash scripts. It functions as an automated utility that rewrites scripts to follow industry standards for quoting and security practices.
The project provides an optimizer and standardizer that replaces unsafe patterns and aliases with safer functional equivalents. It includes a syntax highlighter that uses visual markers and colorization to indicate vulnerabilities and areas where quoting corrections are required.
The tool covers a broad range of capabilities including automated safety remediation, vulnerability detection, and script bug detection. These features ensure script conformance through automated rewriting and structural syntax validation.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
