Welcome

About the Project

A lightweight Unix‑style shell written in C for the 50.005 CSE module. It re‑implements core terminal niceties (raw‑mode input, history, tab‑completion) while showcasing low‑level process control, job management and a suite of mini system utilities.

Features

• Bash‑like prompt with raw terminal mode, arrow‑key history, word jumps and context‑aware tab‑completion.
• Built‑ins: cd, exit, alias / unalias, bins, plus job‑control signals.
• Helper programs in bin/ – find, ld/ldr, sys, and the Tamagotchi‑style dplant suite (dcheck, dkill).
• Strict compile flags (-Wall -Wextra -Werror -fsanitize=address) to keep UB at bay.
• Safety scripts: fixbroken.sh (reset terminal), daemonslayer.sh (kill runaway daemons), qformat.sh (clang‑format).

Usage

1. Clone: git clone https://github.com/rpeky/C-Shell-custom.git
2. Build everything: make
3. Run the shell: ./cseshell
4. Try a helper: dplant sprout then dplant sprout water
