MiniShell

MiniShell is a project designed to introduce students to the fundamentals of Unix shell programming and system calls in the C programming language. Much like Cub3D, MiniShell is part of the curriculum at 42, an innovative coding school focused on peer-to-peer learning and project-based education.

Project Overview:

MiniShell is inspired by Unix shells like Bash or Zsh. The goal of this project is to create a simplified version of a Unix shell, capable of executing basic commands and managing processes.

Features:

Command Execution: Implement the ability to execute commands entered by the user. Built-in Commands: Support built-in commands such as cd, echo, pwd, etc. Environment Variables: Manage environment variables, including setting, displaying, and unsetting them. Redirection: Support input and output redirection (<, >), as well as piping (|) between commands. Signal Handling: Handle signals such as Ctrl+C (SIGINT) and Ctrl+Z (SIGTSTP). Command History: Allow users to access and navigate command history using arrow keys. Tab Completion: Implement tab completion for commands and file paths. Scripting: Support executing shell scripts.

Installation:

To compile and run the MiniShell project, follow these steps: Clone the project repository. Navigate to the project directory. Run the make command to compile the project. Execute the generated executable.

Usage:

./minishell

Controls:

Arrow Keys: Navigate command history. Tab: Autocomplete commands and file paths. Ctrl+C: Interrupt currently running command. Ctrl+D: Suspend currently running command.

Dependencies:

C compiler (gcc or clang) Standard C libraries Knowledge of Unix system calls

Example:

$ ./minishell
$ ls
file1.txt file2.txt directory
$ cd directory
$ pwd
/home/user/directory
$ echo "Hello, world!"
Hello, world!
$ exit
