Do you use the CLI a lot and encounter new Wi-Fi sources, but don't want to/can't remember the commands to connect to the Internet?? I'm lazy. I mean, that's what scripting is for, right?? Efficiency means obtaining the maximum result with maximum laziness. I wrote this small script a while ago and have improved on it several times over the course of about 6 months. I personally like it a lot (obviously, I wrote it) and thought that others might also. So here it is. Also, any comments, ideas, changes, don't hesitate to post!! New ideas and ways of making things work better is always appreciated by everyone.

# Wi-Fi Commander, a lazy way to lazily connect to the WiFi
# Updated: 15-8-16, Version 3.5
# This script requires that nmcli, w3m, and w3m-img (if
# you want to be able to see pictures), are all installed
# on the computer running it
# You must be a sudoer or root to use this script
