# mozshellutil — Shell command line parsing utilities for Mozilla testing

License: copyleft · Maintenance: aging · Downloads: 157.1K/mo

## What it is and what it does

mozshellutil is a utility library from Mozilla's mozbase project that provides shell command-line parsing and argument handling for testing infrastructure. It is designed for developers working on Mozilla testing pipelines who need to parse and manage shell commands and command-line arguments in a standardized way.

The package has no runtime dependencies and supports Python 3.8 through 3.13. With no known vulnerabilities and low install friction, it is straightforward to add to a project. However, the aging maintenance status suggests the package is stable but not actively developed, so it may not receive updates for new Python versions or bug fixes.

Use it for:

- Parse and validate shell command-line arguments in Mozilla testing scripts
- Handle command-line utilities within Mozilla's automated testing infrastructure
- Integrate with mozbase testing tools that require standardized argument processing
- Build shell command wrappers for Mozilla test automation pipelines

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides shell command-line parsing utilities for Mozilla testing infrastructure, handling argument processing and shell interactions.

Yes, if you are working within Mozilla's testing ecosystem and need standardized shell command-line parsing. The package is stable, has no dependencies, and carries no security vulnerabilities. However, be aware that maintenance is aging—expect no active development, and verify that it integrates with your specific workflow before adopting it.

## Install

pip install mozshellutil
uv add mozshellutil
poetry add mozshellutil

## Installing mozshellutil
