#  Update Short Links Base URL Script
#
#  This script updates the base URL (protocol, domain/IP, and port) in the
#  short_links.json file located at /usr/local/bin/Wireguard-panel/src/.
#
#  It performs the following tasks:
#    - If both short_links.json and short_links_decrypted.json exist, removes
#      short_links.json and renames short_links_decrypted.json to short_links.json.
#    - Verifies that the target JSON file exists.
#    - Checks if jq is installed; if not, attempts to install it automatically.
#    - Prompts the user for the new protocol (default is https), domain/IP, and port.
#    - Uses jq to replace the base URL in every entry within the JSON file.
#
#  NOTE: You may need sudo privileges for installing jq and updating the file.
