🦀 Built a Simple grep-like CLI Tool in Rust – Pattern Matching, Highlights, and Match Stats

Hey folks,

I’ve been diving into Rust recently with a strong focus on systems programming and CLI tools. As part of that journey, I built a small utility inspired by grep. It’s a terminal-based tool that searches for a given pattern in one or more files and highlights the matches line by line.

Here’s what it does:

🔍 Features:

• Accepts a pattern and one or more file paths as arguments
• Highlights matches within each line (currently using simple string matching)
• Prints the matched line with its actual line number in the file
• Displays a match count at the end per file
• Gracefully handles file read errors and continues processing others
• Uses eprintln! for error messages and proper exit codes

🧱 Built With:
Rust standard library only — no dependencies (yet).
