🖥️ Custom Terminal Emulator

A simple, lightweight, Python-based terminal emulator that mimics common shell commands like cd, ls, touch, rm, mkdir, echo, and more — all built using only basic Python and standard libraries.

---

🚀 Features

• ✅ Command parsing using shlex
• ✅ Support for common shell commands:
  • cd, ls, pwd, echo
  • cat, mkdir, rmdir
  • rm (with flags support)
  • touch (with -c flag support)
  • clear, exit, ping
• ✅ Handles command-line flags like -c, -rf, etc.
• ✅ Graceful error handling for invalid commands
• ✅ Dynamic prompt showing username and current directory
• ✅ Cross-platform support (cls vs clear)

• os – for interacting with the OS (filesystem, environment, etc.)
• subprocess – for executing system-level commands safely
• shlex – for parsing shell-like syntax

📌 Notes

• You can only run allowed commands (check ALLOWED_COMMANDS dict).
• TERM environment variable not set. error might show when running in an IDE; try running it from a real terminal instead (bash, zsh, etc.).
• Designed to be simple and extensible — feel free to add more custom commands.

🛠️ To Do / Ideas to be implemented in the future

• Add support for command piping (|)
• Implement file redirection (>, <)
• Add a help command (man-like info for built-in commands)
• History & command autocomplete
• Implement history navigation using the Up/Down arrow keys.
