📄 File/Directory Reader CLI

A simple, clean, and flexible command-line file reader written in Rust. It allows you to provide a file or directory path and prints file contents with line numbers — beautifully formatted. 🚀

✨ Features

• 📁 Reads a single file and prints it with aligned line numbers.
• 📂 Reads multiple files inside a directory (you choose how many).
• 🔢 Smart input handling for selecting number of files.
• ❌ Option to cancel at any moment.
• ⚠️ Clear error messages for invalid paths or unsupported types.

🧠 How It Works

Just run the CLI with a path (file or directory).

• If it's a file, it prints the content line by line.
• If it's a directory, you'll be asked how many files you want to read.
• Uses standard input/output for interactive prompts.

No deep project structure explanation here — so the README won’t become outdated after changes. 😉

🚀 Usage

1. Run with a file path

cargo run -- path/to/file.txt

2. Run with a directory path

cargo run -- path/to/directory

Then choose:

• 0 → read all files
• N → read N files
• -1 → cancel
