See the addendum for "short version" of this post.

I am trying to understand processes / files used in initializing WiFi. I know that wpa_suppllicant.conf is part of the process. To verify that I used raspi-confing option to implement WiFi and checked the contents of wpa_supplicant.conf file for changes. It did not change. . I went back to raspi-config and changed WiFi country, rebooted and again checked the wpa_suppllicant.conf. The country DID NOT change.

As part of my tests I changed to ubuntu MATE , unfortunately there was no option to implement WiFi, but I noticed when some other options were actually being configured I saw what appeared as terminal output in the background of the desktop.

Two questions - am I looking at correct wpa-supplicant.conf in /etc/wpa_supplicant directory ? Is there a way to actually get "verbose" output from raspi-config to see what is being implemented?

Thanks appreciate any help

OK, found "source " on git hub So how do I find it in Raspian and add "echo " to it??

  • "which raspi-config" will show you where the executable lives. – NomadMaker Aug 2 '18 at 23:30

Check which raspi-config. Pretty sure it is /usr/bin/raspi-config. There's probably not much point in adding any echo, since if you can figure out where to put them, you'll be figuring out what it actually does (follow the menu options, the main one is I think at the bottom, you can then search the script for the function calls).

  • Yes, found the file. I need to learn how to do grep ...My next post is going to be " my RPi won'r boot..." after I get thu modifying. – Jan Hus Aug 3 '18 at 18:11
