Opening this issue on behalf of @cmavian (see issue #246 )
I think it would be beneficial to introduce the touch command before nano to show the students an alternative way to make a file, and then introduce nano to modify and also create a file.
'touch' is certainly useful! Unfortunately, I think that the lesson is quite full already as it is. But maybe this is something that would fit in 'Extra'? Let me know if you plan to submit a pull request
