i want to see what are the passwords to the wifi connections that i have used, but i don't know how to open these files. tried this solution, but i don't have thunar installed apparently. i know i can install it easily using apt-get, but i really have no idea what it is or what filetype is those files. would be glad if anyone could help, as you may have guessed I'm very new to the linux world.
The files in
/etc/NetworkManager/system-connections/ are simple text files and you can view them using
cat or edit them with any text editor. But you must use
sudo or administrator password to do so.
To open a file
tt in that folder, I'd use this command
sudo -i gedit /etc/NetworkManager/system-connections/tt
