## #############################################################################
## About:        This script will prompt the user to connect to a wireless
##               network ssid and make a launcher script to
##                  log into known wpa_supplicant ssid configurations.
## Instructions: Run this script in the root account to make a new
##                  wpa_supplicant account profile.
##               Run this script in a user account to generate a script which
##                  logs in/out of known ssids.
## Source Code:  https://github.com/mezcel/headless-host/my_iwconfig.sh
## Dependency:   Requires wpa_supplicant and net-tools on Debian
