Open Source C++ System Shells for Linux

Finally, a command line shell for the 90s. fish is a smart and user-friendly command line shell for Linux, macOS, and the rest of the family. fish suggests commands as you type based on history and completions, just like a web browser. Watch out, Netscape Navigator 4.0! fish supports 24 bit true color, the state of the art in terminal technology. Behold the monospaced rainbow. fish is fully scriptable, and its syntax is simple, clean, and consistent. You'll never write esac again. For those lucky few with a graphical computer, you can set your colors and view functions, variables, and history all from a web page. Other shells support programmable completions, but only fish generates them automatically by parsing your installed man pages. fish will delight you with features like tab completions and syntax highlighting that just work, with nothing new to learn or configure.

Squirrel Shell is a cross-platform alternative to system shells like bash in Linux and cmd.exe in Microsoft Windows. It is based on scripting language "Squirrel".

Mainly this project aims at easing startup and use of XCSoar (see xcsoar.org) on Kobo Mini. But the scope of use should not be limited solely to XCSoar. The Launcher should be small in code size, reuse most of the original libraries, provide flexible configuration to any application that might be ported to the Kobo Mini. It supports customizable fonts, toolbox-pages, buttons (also graphical), labels, autostart and sleep timers.

KonsolScript is an embeddable scripting runtime for games, tools, automation, and AI-driven applications. Add a live scripting layer to any C++ application. Hot-reload behavior, patch running apps, and orchestrate AI workflows - without rebuilding or redeploying the binary. Ship once. Evolve forever. Key capabilities: - Embed into any C++ app with a single header - Hot-reload scripts at runtime without restarting - AI-safe: validate or reject scripts before execution - Orchestrate LLMs (OpenAI, Claude, Gemini, Ollama) in .ks scripts - Built-in: String, File, JSON, CSV, Math, Regex, and more - Plugins: HTTP, SQLite, MySQL, TCP, Redis, Crypto, JWT, Zip - Push behavior updates to remote instances over TCP Use cases: - Scriptable game engines (hot-patch rules mid-session) - AI event bridges (natural language to live app behavior) - Automation pipelines (CI, log triage, file processing) - LLM orchestration workflows Docs: https://konsolscript.sf.net/kookbook.html

SoupToNuts is a repository of technical articles and example software covering Postfix, OpenSSH, C and C++, Live Linux CD, MySQL, SQLite, Berkeley DB, Bash and System Administration.

Dreamos is an operating system developed on Sega Dreamcast to be ported to an array of embedded devices. The goal of the project is to be able to run non-ported Unix programs on the Sega Dreamcast and other embedded devices with ease and POSIX compliance

this is a very primitive dos multitasking gui i think it will help alot of people with window management it also comes with some example progams

SBD is a way of leaving ultra-secure minimal access to a computer, which allows you to run a single command based on a one time key. It is good if you don't want to have an ssh server running all the time, but only want to start it when needed.

FLoM is a free open source distributed lock manager that can be used to synchronize shell commands, scripts and custom developed software. When used in a shell environment, FLoM manages process synchronization in the same way that "nice" manages process prioritization. Shell commands, scripts and custom programs can be synchronized inside a single system or in a network of IP connected systems. FLoM supports different types of abstract resources: simple, numeric, set, hierarchical and transactional sequence. libflom, the library shipped with FLoM, allows you to develop your own application using a simple C, C++, Java, Perl, PHP or Python client API. SSL/TLS security for network communication, X.509 certificates for peer to peer mutual authentication.

Sakura is a Knowledge Navigator and User Interface for UNIX, which implements HyperMedia and its own windowing and packing system, both in the main program and in an extensive API for Tcl and other languages.

This is a collection of small utilities written for use in Windows CMD scripts. However some of the utilities are also useful for use in UNIX shells.

Hosh is a shell for fun. There are commands like "make world" as well as "configure" which checks the whole machine - even the power status and the coffee temperature.

3D-Console is a system that maintains and renders a general purpose user interface for multiple applications in a shared three dimensional virtual space. The applications are arbitrary operating system processes, as we know them.

The purpose of the project is to make the bash behave intelligent. This includes currently corrrection of mistyped program names, autocorrection while pressing TAB and learning which program are associated with which suffix.

Auto-Case is a script wriiten in C++ that converts your mistake into perfection. Or in simple terms it converts LowerCase ↔ UpperCase But For Who? ------------------------------------------------------------------------------------------------------------------------- - Ever typed something in wrong case (UPPER/LOWER), yes! - So,all you can do is press backspace all the way and again retype your words - Do no more, Auto-Case does the work for you all one key press away. ------------------------------------------------------------------------------------------------------------------------- How to use? ------------------------------------------------------------------------------------------------------------------------- see here---> https://github.com/AsishRaju/Auto-Case -------------------------------------------------------------------------------------------------------------------------- Please read the readme file inside the zip file.

The goal of the Basic Operating System (BOS) project is to write a new modular and fast operating system in NASM and GCC.

Cextraz is a set of linux/unix commandline aliases and scripts to make it easier for a enduser with very little knowledge to use the terminal. Maybe someone thats just migrantedd from windows or mac. Note, its beta. More features to come.

Linux shell written in C++ which will eventually include scripting and other advanced features

Cursed Menu aims to create an ncurses based menu system for character terminal sessions. This menu program could be used to create user, system administration, or utility menus for clients connecting with text based clients such as telnet, ssh, or rlogin

Cyb@rg is an experimental and universal real time terminal emulator. The project allows to execute shell commands through a cross-platform user interface. Cyb@rg has been designed to improve command line handling on the most known operating system.

A small, portable shell written in C++. This project is intended as an exercise to improve my programming skills. The goal of this project is to create a DOS-like shell that cross-compiles on Linux and Windows.

Darimasen seperates directory navigation and file operations, using a menu-based system.

Elektra provides a mature, consistent and easily comprehensible API. Its modularity effectively avoids code duplication across applications and tools regarding configuration tasks. Elektra abstracts from cross-platform-related issues and allows applications to be aware of other applications' configurations, leveraging easy application integration. See http://www.libelektra.org for more information.

This project is targeted to consolidate Embedded Linux Tools Chain under Windows. Most of the cross complication tools are compiled using cygwin.

Erc is an interpreted link-oriented language. Majic is a java-based interpreter for Erc, and Majicc is a c++ based compiler for Erc which uses the Majic libraries.
