We’ll begin by learning to use a simple, command line text editor called nano.
In the terminal, type
This will open the nano text editor.
In nano, at the top of the window, type
"Hello, I am nano."
I did that.
Then the instructions say:
Using the menu at the bottom of the terminal for reference, type Ctrl + O (the letter, not the number) to save the file. This is the letter “O”, not the number zero. (so do I type; “Ctrl + O” , “Ctrl O” , “CtrlO”? I’ve tried all three and nothing happens. No promt about file name as it says would happen below. and when I try Ctrl + X, nothing happens either.
Press Enter, when prompted about the filename to write.
Then type Ctrl + X to exit nano.
Finally, type clear to clear the terminal window. The command prompt should now be at the top of the window.
