# Nginx Proxy Manager CLI Script
# Erreur32 - July 2024
#
# This script allows you to manage Nginx Proxy Manager via the API. It provides
# functionalities such as creating proxy hosts, managing users, listing hosts,
# backing up configurations, and more.
#
# Usage:
#   ./nginx_proxy_manager_cli.sh [OPTIONS]
#
# Examples:
#   ./nginx_proxy_manager_cli.sh -d example.com -i 192.168.1.10 -p 8080 -s true
#   ./nginx_proxy_manager_cli.sh --create-user newuser password123 user@example.com
#   ./nginx_proxy_manager_cli.sh --delete-user 'username'
#   ./nginx_proxy_manager_cli.sh --list-hosts
#   ./nginx_proxy_manager_cli.sh --backup
#
# Advanced proxy tab example:
#   ./nginx_proxy_manager_cli.sh -d example.com -i 192.168.1.10 -p 8080 -a "proxy_set_header X-Real-IP \$remote_addr; proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;"

#   -n DNS_CHALLENGE           DNS challenge (true/false, default: false)
#   -t TOKEN_EXPIRY            Token expiry duration (default: 1y)
#   --create-user user pass    Create a user with a username and password
#   --delete-user username     Delete a user by username
#   --delete-host id           Delete a proxy host by ID
#   --list-hosts               List the names of all proxy hosts
