When you are installing ArcoLinuxD you start with a TTY screen. It is all black and you type what you want to accomplish. I wanted to get rid of the ‘ugly’ shutdown lines and I knew what to do but wondered what the exact code was again.
You can install links:
sudo pacman -S links
And then surf with links to https://arcolinux.com and search for shutdown to find the article with the answer and that in the TTY.
This was assuming you have only one pc and no smartphone.
How do you find your answer then?
