Introduction

The shell is a command-line interpreter that offers a user interface for the operating system's services.

MiniShell replicates some of the basic functionalities of a Unix-like command-line user interface.

Features

MiniShell supports the following features:

• Displaying a prompt when waiting for a new command.

• Executing commands with their parameters.

• Handling absolute and relative paths for commands.

• Redirections: < (input), > (output), >> (output in append mode), and << (input until a delimiter).

• Pipes (|): the output of each command in the pipeline is connected to the input of the next command via a pipe.

• Environment variables expansion: $ followed by a sequence of characters.

• Special variable expansion: $? (the exit status of the most recently executed foreground pipeline).

• Ctrl-C, Ctrl-D, and Ctrl-\ signals handling.

• Built-in commands: echo, cd, pwd, export, unset, env, exit.

Getting Started

To compile, run make. This will create an executable named minishell.

Start the program by running:

./minishell

Builtins

MiniShell implements the following builtins:

echo with option -n

cd with only a relative or absolute path

pwd with no options

export with no options

unset with no options

env with no options or arguments

exit with no options
