I can also get along without electricity too. And refrigeration.
My full screen menu
Hardly primitive and I rarely use the terminal. I can do an update faster via the terminal than opening up the GUI program for it. Hit F12 to open my terminal and type sudo apt-get update
and sudo apt-get upgrade
I do have one program that is command line only.
It's a video downloader that will download from youtube plus hundreds of other websites.
cd Videos
takes me to my video folder and youtube-dl https://www.youtube.com/watch?v=tNcpAQPpIOE
will download the best quality version of that video.
youtube-dl -F https://www.youtube.com/watch?v=tNcpAQPpIOE
will list all the video only, audio only and video + audio formats available and give me 2-3 digit numeric codes for them.
youtube-dl -f 18 https://www.youtube.com/watch?v=tNcpAQPpIOE
is that same highest quality as not using the argument.
Works on most any website or webpage with a video on it. All the browser addons for that are bloated and/or make you sign up to get the best quality versions.
