# 2. Make it executable: chmod +x /usr/local/bin/docker-attila
# 3. To run in the background: nohup docker-attila > /dev/null 2>&1 &
# 4. Stop it anytime with CTRL+C
#
# ⚠️ WARNING:
# This script will permanently delete all Docker containers, images, volumes, and networks.
# Use with caution, especially on production machines!
#
# Dependencies:
# - Docker (ensure it is installed and running)
#
