turt - Tiny UNIX REPL Terminal

turt is a simple shell written in C. (This repository contains a working version. More advanced features are currently in development.)

Features

• Parses and executes external commands (like ls, ps, grep).

• Handles built-in commands (exit, cd).

• Line editing, history (Up/Down arrows), and Tab-completion via GNU readline.

Building from Source

Dependencies

This project depends on the GNU readline library for all input handling.

On Debian/Ubuntu (or WSL):

sudo apt update
sudo apt install libreadline-dev

On macOS (using Homebrew):

brew install readline

(Note: You may need to modify the Makefile on macOS to point to Homebrew's readline path, as macOS uses a different library by default.)

Compiling

Once all dependencies are installed, just run make:

make

Running

./turt

Cleaning up build files

make clean
