A smarter shell and scripting environment with advanced features designed for usability, safety and productivity (eg smarter DevOps tooling)

IPython is an interactive computing environment and programmable extension of the Python read-eval-print loop. It serves as a development tool for writing, testing, and executing code in a live environment designed for rapid prototyping and data exploration. The system differentiates itself through a specialized set of magic commands for environment configuration and system shell integration. It features an object introspection engine for analyzing live program objects at runtime and a frontend-agnostic kernel that allows the execution logic to be embedded into other applications or graphical

PowerShell is a cross-platform task automation and configuration management framework. It functions as an object-oriented shell environment and a dynamic scripting language, enabling users to interact with system interfaces and manage infrastructure through a unified command-line interface. By executing as a managed application on the common language runtime, it provides direct access to native libraries and system APIs. The system is distinguished by its object-based pipeline, which processes structured data objects rather than raw text, allowing for precise property manipulation across comm

This is a collection of academic programming projects that accompany an operating systems textbook, designed to teach core OS concepts through hands-on implementation. The projects span the major subsystems of an operating system, including process scheduling, memory management, file systems, and concurrency, with students building components from scratch in a simulated environment. The projects are structured to cover the full range of OS internals, from low-level kernel development to user-space system programming. Students implement lottery-based CPU schedulers, dynamic heap memory allocat

Powerline is a statusline and prompt generation framework designed to provide consistent visual information across terminal shells, text editors, and multiplexers. It functions as a configuration-driven customization engine that allows users to define themes, color schemes, and dynamic segment layouts to maintain a cohesive interface across diverse command-line environments. The system utilizes a persistent background daemon to manage state and rendering logic, which offloads processing tasks to minimize resource consumption and ensure high responsiveness across multiple active application in

This project is an educational operating system kernel designed to demonstrate the fundamental architectural principles of memory paging and process management. It is implemented as a minimal kernel that serves as a practical reference for building a functioning system from the ground up. The implementation features a preemptive multitasking kernel that switches execution contexts between threads to share a single CPU. It includes an x86 virtual memory manager that uses paging to map virtual addresses to physical memory and isolate processes. The system covers low-level hardware interfacing

A minimal POSIX shell

🖥️ a cross-platform modern shell.

PathPicker is a command line file selector and interactive shell file picker that serves as a bridge between terminal output and external tools. It converts text output from shell commands into a visual list, allowing users to identify and isolate specific file paths for further action. The utility parses text streams from tools such as git or grep to identify file paths, which users can then filter and select via an interactive interface. These selected paths are injected into configurable command templates or passed as arguments to external processes, such as text editors or custom shell sc

howdoi is a command-line coding answer engine that retrieves programming solutions and code snippets from the web for display directly in the terminal. It functions as a web-based code search tool that uses natural language queries to find technical answers without requiring a web browser. The tool provides a JSON-exportable query system, allowing search results to be output as structured data for integration with other software and text editors. It features terminal-based knowledge retrieval that includes local caching and stashing of answers to reduce network latency and avoid search engine

Guake is a drop-down terminal emulator for Linux built on the VTE widget, designed to appear instantly with a single configurable hotkey. It mimics the quake-style console by sliding down from the top of the screen, supporting full-screen toggling and transparency. The terminal manages multiple sessions as named tabs, with automatic naming from the running command and customizable switching shortcuts. It also adapts to multi-monitor setups by placing the window on the monitor under the mouse cursor or a designated screen. Guake stands out with its ability to detect file paths and URLs in term

✨🌙 An advanced, comfortable Lua-configured (Unix/Windows) shell. 🌺

Portable OpenBSD ksh, based on the Public Domain Korn Shell (pdksh).

HTTPie is a command-line HTTP client and REST API debugger used for sending requests to web services. It functions as a network tool for managing headers, authentication sessions, and file uploads, with a specific focus on the transmission and reception of JSON data. The tool utilizes a custom parsing layer to translate simplified command-line input into structured HTTP parameters. It provides ANSI-based terminal formatting to apply color and structural indentation to raw responses, improving human readability for web debugging. The project covers request construction and previewing, multipa

Fisher is a plugin manager and shell extension manager specifically for the Fish shell. It provides a system for installing, updating, and removing plugins, themes, functions, and completion scripts. The tool uses a flat-file state persistence method to track installed extensions in a plain text file, which enables the synchronization of shell environments across different systems using version control. It covers the full lifecycle of shell extensions, including the discovery of installed plugins, the installation of packages from remote repositories, and the development of distributable she

A basic UNIX shell implementation in C

SHell In Ruby? Totally!

This project is a static analysis tool and linter designed to improve the quality, reliability, and portability of shell scripts. By performing deep structural analysis, it identifies common programming pitfalls, syntax errors, and security vulnerabilities before scripts are executed. It functions as an automated code reviewer that enforces best practices and helps developers maintain consistent, robust code across different operating environments. The tool distinguishes itself through its dialect-aware grammar resolution, which adapts its parsing logic based on the specific shell interpreter

UnBloated (or Undefined Behavior...) shell. A small and lightweight non-POSIX shell.

Nash stands for Nash shell.

A new Unix shell.

A command-line shell like fish, but POSIX compatible.

This project is a configuration framework for the Fish shell, providing a centralized system for managing plugins, themes, and custom environment settings. It functions as a plugin manager and theme engine that allows users to install, update, and remove functional extensions and visual styles. The framework includes a shell extension scaffolder that generates standardized directory structures and boilerplate files for creating new plugins and themes. To ensure quality, it provides a specification-based testing suite for validating package functionality through automated assertions. The syst

This project is a configuration framework and environment manager for the Zsh shell. It functions as a plugin manager and prompt theme engine, automating the installation, organization, and updating of terminal workflow configurations. The framework decouples visual presentation from shell logic using a library of interchangeable themes and a prompt engine that supports asynchronous rendering to maintain interface responsiveness. It employs a plugin-based architecture to inject custom aliases and specialized tools into the shell session. Users can manage shell settings and environment variab
