This project is a custom implementation of a shell, similar to bash or zsh. It is a school project that aims to create a simple yet functional command-line interpreter.

The Minishell project is a classic exercise in system programming. It involves parsing user input, managing processes, and interacting with the operating system's kernel. This implementation is written in C and uses the readline library for input handling.

The project is structured into several modules:

• shell/: Core shell functionality, history, and utilities.
• environment/: Environment variable management.
• runtime/: Command execution, redirection, and expansion.
• lexical_a/: Lexical analysis and tokenization.
• syntax_a/: Syntax analysis and here-doc handling.
• builtins/: Implementation of built-in commands like cd, echo, pwd, etc.
• optimization/: Command and here-doc optimization.
• library/: Contains libft and get_next_line.

To get a local copy up and running, follow these simple steps.

You need to have git and make installed on your system. You also need the readline library.

On Debian/Ubuntu, you can install it with:

sudo apt-get install libreadline-dev

1. Clone the repo

   git clone https://your_repo_link/minishell.git
   

2. Navigate to the project directory

   cd minishell
   

3. Compile the project

   make
   

This will create the minishell executable in the root directory.

To start the shell, run the following command:

./minishell

You will be greeted with a new prompt, ready to accept your commands.

Here are some examples of what you can do with Minishell:

• Simple commands

  ls -l
  

• Pipes

  cat file1 | grep "hello"
  

• Redirections

  ls > file.txt
  cat < file.txt
  

• Here-doc

  cat << EOF
  hello
  world
  EOF
  

• Built-in commands

  echo "Hello, World!"
  cd /path/to/dir
  pwd
  export VAR="value"
  unset VAR
  env
  exit
  

To remove the object files, run:

make clean

To remove the object files and the minishell executable, run:

make fclean
