Hi DavidLee1A, Welcome to LQ. You don't run the conf file, you run wpa_supplicant with the options per the instructions and wpa_supplicant should read from the conf file. When you run the following you are telling wpa_supplicant where the conf file lives.
wpa_supplicant -i eth1 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf
The path to the conf file is in red. Hope that clears it up for you.
Good luck. ;-)
