Simple Linux Shell

Author: Sahaj Singh

This repository contains the code for a simple Linux shell developed as part of a lab assignment. The shell accepts user commands and then executes each command in a separate process, providing the user a prompt at which the next command is entered. The shell supports internal commands, maintains command history, and can handle signals.

Features

  1. Executes user commands in a separate process.
  2. Supports internal commands: exit, pwd, cd, and help.
  3. Maintains the history of the last 10 commands executed.
  4. Supports the !n and !! commands for executing commands from history.
  5. Handles the SIGINT signal to display help information.
  6. Displays the current working directory in the shell prompt.

Optional Feature

  1. Enhanced cd command to support changing to the home directory, using ~ for the home folder, and - for changing back to the previous directory.

Getting Started

git clone https://github.com/yourusername/simple-linux-shell.git
