# Minishell

Minishell is a simple shell program written in C. It provides a command-line interface that allows users to interact with their computer through a series of commands. This project aims to replicate the functionality of a basic shell, similar to Bash, and provides a set of features and functionalities that allow users to execute commands, handle processes, and perform various operations on files and directories.

## Features

- **Prompt**: Minishell displays a prompt when waiting for a new command, indicating that it is ready to accept user input.

- **Command Execution**: The shell searches for and launches the appropriate executable based on the PATH variable, or using a relative or absolute path.

- **History**: Minishell maintains a working history of previously executed commands, allowing users to navigate and recall previous commands.

- **Quotes Handling**: The shell interprets and handles single quotes ('), preventing the interpretation of metacharacters within the quoted sequence. Double quotes (") prevent interpretation of metacharacters, except for the dollar sign ($).

- **Redirections**: Minishell supports input (<) and output (>) redirection, allowing users to redirect the input or output of a command to/from a file. Append mode (>>) for output redirection is also supported. Here documents (<<) can be used to read input until a specified delimiter is encountered.

- **Pipes**: The shell supports pipes (|) to connect the output of one command as the input of another command in a pipeline.

- **Environment Variables**: Minishell handles environment variables ($ followed by a sequence of characters) and expands them to their corresponding values.

- **Built-in Commands**: The shell implements several built-in commands, including echo, cd, pwd, export, unset, env, and exit.

- **Signal Handling**: Minishell handles signals such as ctrl-C, ctrl-D, and ctrl-\ in an interactive mode, providing behavior similar to Bash.

## Bonus Features

In addition to the mandatory requirements, the Minishell project includes the following bonus features:

- **Logical Operators**: The shell supports logical operators (&& and ||) with parentheses for priorities.

- **Wildcard Expansion**: Minishell implements wildcard (*) functionality for the current working directory.

Please note that the bonus part will only be evaluated if the mandatory part is implemented perfectly.

## Getting Started

To compile and run Minishell, follow these steps:

1. Clone the repository: `git clone `

2. Navigate to the project directory: `cd Minishell`

3. Compile the source code: `make`

4. Run Minishell: `./minishell`
