Mini-Shell Project

This project implements a simplified command-line shell interpreter. The Mini-Shell provides basic shell functionalities like command execution, redirections, pipelines, and job control (background processes), offering features similar to popular shells like Bash or PowerShell.

Features

• Execution of basic shell commands.
• Redirection of input/output using < and >.
• Support for pipelines (|) for chaining commands.
• Job control (e.g., running processes in the background).
• Basic handling of signals (Ctrl+C, Ctrl+Z).

Files

• minishell.c: Provides additional functions for process and signal handling.
• job.c: Manages jobs and their states.
• readcmd.c: file for reading and parsing commands.

Requirements

• GCC compiler or any C compiler supporting POSIX standards.
• Unix-like operating system (Linux or macOS recommended).

Installation

1. Clone this repository to your local machine:

   git clone <repository_url>
   cd <repository_folder>

2. Compile the program using gcc:

   gcc -Wall -o minishell readcmd.c minishell.c job.c -lpthread

How to Execute

1. Run the compiled Mini-Shell:

   ./minishell

2. You will see a prompt similar to:

   arhayout@Minishell:~$ 
   

   Start typing commands to execute them.

Usage Examples

• Run a basic command:

  arhayout@Minishell:~$ ls -l

• Run a command in the background:

  arhayout@Minishell:~$ sleep 10 &

• Redirect output to a file:

  arhayout@Minishell:~$ ls > output.txt

• Use a pipeline:

  arhayout@Minishell:~$ cat file.txt | grep keyword

Known Limitations

• Some signal handling (e.g., Ctrl+Z, Ctrl+C) is not fully functional.
• Complex pipelines or advanced shell functionalities (like command history) are not supported.

Future Improvements

• Add a command history feature.
• Improve signal handling and error recovery.
• Implement additional built-in commands for better usability like tabulations
