+# 🛠 Directory Comparator
+
+A robust Bash utility for recursive file comparison between two directories. It uses DIR_A as the source of truth for file names and checks for their existence and differences in DIR_B. Perfect for auditing configuration changes or verifying backup integrity.
+
+---
+
+### ⚙️ Prerequisites
+* **diff:** Used for generating file differences.
+* **find:** Required for recursive file discovery.
+* **Bash 4+:** Utilizes modern bash features like `set -euo pipefail`.
+
+### 📊 Parameters Mapping
+| Option | Description |
+| :--- | :--- |
+| -o | Save the full report to a specific file (default: `./compare-dirs.log`). |
+| -q | Quiet mode: Show only the final summary without full `diff` output. |
+| -h | Show help and usage information. |
+
+### 🏃 Quick Start
+```bash
+ # Basic comparison (outputs diffs to terminal and compare-dirs.log)
+ ./compare-dirs.sh /path/to/dir_a /path/to/dir_b
+
+ # Quiet mode (summary only) with custom log file
+ ./compare-dirs.sh -q -o audit_report.log /etc/nginx /backup/nginx
+```
+
+### 🛡 Features
+* **Safe Discovery:** Uses `-printf '%P\0'` with `find` to safely handle filenames with spaces or special characters.
+* **Strict Execution:** Built-in error trapping and strict mode to prevent silent failures.
+* **Colorized UI:** Visual feedback for **IDENTICAL**, **DIFFERENT**, and **MISSING** status.
+* **Log Rotation Ready:** Outputs to both `STDOUT` and log files simultaneously.
