Last listed files presumably have higher precedency then files listed first, i.e. configuration files in the personal .config directory will be listed last and their config parameters will be more authoritative then default config parameters defined in /etc directory which are usually listed above them.
If you replace ".conf" with ".ini" in the command, initial files will be listed instead of config files.
If you do not like to list multiple access to the same config file, pipe to "uniq" or "uniq -c" to prefix lines by the number of occurrences

A great way of viewing some man page while using gnome.
-B flag = don't include characters that can be confused for other characters (this helps when you give someone their password for the first time so they don't cause a lockout with, for example, denyhosts or fail2ban)
-s flag = make a "secure", or hard-to-crack password
-y flag = include special characters (not used in the example because so many people hate it -- however I recommend it)
"1 10" = output 1 password, make it 10 characters in length
For even more secure passwords please use the -y flag to include special characters like so:
$ pwgen -Bsy 10 1
