FSH (Flex Shell)

FSH is a custom-built Linux shell written in C++ designed to offer a flexible, lightweight, and expandable command-line interface. This project marks my initial journey into understanding shell internals, process management, and system programming, with many more features planned for the future.

🚀 Current Features

Basic Command Execution:
Run standard Linux commands like ls, pwd, echo, etc.
Argument Handling:
Parse and manage command-line arguments for robust command execution.
Built-In Commands:
- exit: Terminate the shell.
- cd <directory>: Change the current working directory.
- history: Display a list of previously executed commands.
Process Management:
Leverage fork() and execvp() for command execution in separate processes.
Real-Time Clock:
Display the current time in the shell prompt.

🔮 Planned Features

Environment Variable Support:
Manage and export environment variables.
Input/Output Redirection:
Support redirection operators like > and <.
Piped Commands:
Enable command chaining with pipes (|).
Background Execution:
Execute commands in the background using &.
Tab-Based Auto-Completion:
Enhance usability with command and file name auto-completion.
Additional Enhancements:
Continuous improvements and refinements as I dive deeper into shell programming.
