Introduction

A shell is a fundamental component of any operating system. It allows users to interact with the system by providing a text-based interface for running commands and managing processes. The Simple Shell project aims to provide a basic understanding of how a shell works and how it can be implemented.

Features

• Command Execution: The shell can execute various shell commands and external programs.

• Change Directory (cd): Users can change their current working directory using the cd command.

• Exit: The shell handles the exit command to terminate the shell.

• Error Handling: The shell provides basic error handling for invalid commands and situations.

Getting Started

To get started with the Simple Shell, follow these steps:

1. Clone the repository to your local machine:

   git clone https://github.com/your-username/simple-shell.git

2. Compile the code:

   gcc -o hsh *.c

3. Run the shell:

   ./hsh

Usage

The Simple Shell supports basic shell commands and external programs. Here are some examples of how to use the shell:

• Running a command:

  '$ ls'

• Changing directories (cd):

  '$ cd /path/to/directory'

• Exiting the shell:

  '$ exit'

Please note that this is a minimal shell and does not support all the features of a full-featured shell like Bash.

• ls: List files and directories in the current directory.
• cd: Change the current working directory.
• pwd: Print the current working directory.
• echo: Print arguments to the standard output.
• cat: Concatenate and display the content of files.
• exit: Exit the shell.
• ...

Error Handling

The shell includes basic error handling. It can detect and handle various error conditions, such as:

• Invalid commands.
• Issues with executing external programs.
• Errors related to changing directories.
