nsh — Nyx Shell

A small Unix shell written in C++ from scratch.

⚠️ Early development: nsh is currently in a very early stage of development. The interactive loop runs indefinitely and can be stopped with Ctrl+C.

Current Functionality

• Interactive command input
• Command argument parsing
• External command execution
• exit builtin

Build

cmake -S . -B build
cmake --build build

Run shell

./build/nsh

Run tests

./build/parser_test
./build/executor_test

Yes, it runs commands. No, it won't replace your shell anytime soon.
