🛠 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

    # Clone the repository
    git clone https://github.com/andsyrovatko/s4k-admin-toolbox.git
    cd s4k-admin-toolbox

    # Grant execution rights to the scripts
    cd tools/linux/compare-dirs && chmod +x compare-dirs.sh

    # 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.
