Minishell

Minishell is a mini version of a Unix shell, created as a school project with Bash as the reference shell. The goal of this project is to implement essential features of a shell environment from scratch, deepening our understanding of process creation, signal handling, and command execution.

This project was a collaborative effort, with each contributor responsible for different aspects of the shell.

Parts Handled by me:

• Parsing and Tokenization (Fully Implemented): Efficiently parses and tokenizes user input for command processing.
• Command Execution (Fully Implemented): Executes system commands, handling both relative and absolute paths.
• Pipes (Fully Implemented): Implements piping (|), enabling the chaining of commands.
• Redirection (Fully Implemented): Handles input (<), output (>), and append (>>) redirection.
• Environment Variables (Fully Implemented): Manages environment variables like $HOME and $USER.
• Heredoc (Collaboration): Includes partial functionality for heredoc (<<).
• Signal Handling (Collaboration): Basic signal handling (e.g., Ctrl+C and Ctrl+).
• Error Handling (Partially Implemented): Provides error management for invalid commands and syntax, with some areas still under development.
• Built-in Commands (Improved): Fixed edge cases for built-in commands (echo, cd, pwd, export, unset, env, exit).

Parts Handled by partner:

• Initial Pipex Implementation (Fully Implemented): Provided the foundational code for pipe handling.
• Prompt (Fully Implemented): Displays a customizable shell prompt.
• Built-in Commands: echo, cd, pwd, export, unset, env, exit
• Error Handling (Partially Implemented): Provides appropriate error messages for invalid commands or incorrect usage.
• Signals (Collaboration): Implements signal handling (e.g., Ctrl+C, Ctrl+) to manage shell behavior.
• Heredoc (Collaboration): Includes partial functionality for heredoc (<<).

Compilation

1. Clone the repository:

git clone [email protected]:k2matu/minishell.git

2. Navigate into the directory:

cd minishell

3. Compile the library using make:

make

4. Run the shell:

./minishell

Usage

Once the shell is running, you can execute commands similarly to Bash!
