Checks connection and auto connect to Cloudflare Warp

Cloudflare Warp Status Check Script

This bash script checks the status of Cloudflare Warp for a given endpoint (https://cloudflare.com/cdn-cgi/trace). It uses curl to make a HTTP request to the specified URL, checks if the response contains "warp=on" or "warp=plus", and acts accordingly.

Prerequisites

Before running the script, make sure you have the following tools installed on your system:

  • curl: A command-line tool for making HTTP requests. You can install it with a package manager like apt, brew, or yum.
  • warp-cli: A command-line interface for managing Cloudflare Warp. Follow Cloudflare's instructions to install it.

# Comments and complaints http://www.nicknorton.net
# GUI for mouse wheel speed using imwheel in Gnome
# imwheel needs to be installed for this script to work
# sudo apt-get install imwheel
# Pretty much hard wired to only use a mouse with
# left, right and wheel in the middle.
# If you have a mouse with complications or special needs,
# use the command xev to find what your wheel does.
