ShellBrunbaix

Description 📜

ShellBrunbaix is a basic shell written in C that reads user input, tokenizes the input, and executes commands. It mimics some basic functionalities of standard Unix shells by allowing users to execute external commands like ls, pwd, echo, etc., and includes the ability to exit the shell with the exit command and to change directory with the cd command.

Features ⚙️

• Reads and processes user commands.
• Tokenizes the input into command and arguments.
• Uses fork and execvp to execute external commands in child processes.
• Handles simple error cases and displays appropriate messages.
• Allows exiting the shell with the exit command.
• Allows to change directory with cd.
• Prompt change based on the username & the current directory.

Future Improvements 🔄

Here are some features that could be added to enhance the functionality of ShellBrunbaix:

• Input/Output Redirection: Allow users to redirect the output of commands using > or <.
• Pipe Handling: Implement support for piping (|) between commands.
• Command History: Keep track of previously entered commands and allow the user to access them.
• Autocomplete: Add support for tab-completion of commands and file paths.
