# File:
# nginx-modsite
# Description:
# Provides a basic script to automate enabling and disabling websites found
# in the default configuration directories:
# /etc/nginx/sites-available and /etc/nginx/sites-enabled
# For easy access to this script, copy it into the directory:
# /usr/local/sbin
# Run this script without any arguments or with -h or --help to see a basic
# help dialog displaying all options.

# This script manages NGINX sites, providing functionality for enabling/disabling,
# listing, and editing site configurations. It simplifies the process of managing
# NGINX sites by providing a command-line interface for common operations.
#
# Usage:
# ./nginx-sm.sh [options]
#
# Options:
# -e, --enable Enable a site by enabling its configuration file.
# -d, --disable Disable a site by disabling its configuration file.
# -l, --list List all available sites and their status.
# -ed, --edit Edit the configuration file of a site.
#
# Examples:
# ./nginx-sm.sh --enable example.com # Enable the site example.com
# ./nginx-sm.sh --list # List all available sites
# ./nginx-sm.sh --edit example.com # Edit the configuration of example.com
#
# Dependencies:
# - NGINX web server must be installed and running.
# - The script requires sudo privileges to modify NGINX configuration files.
