I was doing something else but came across mention of a book by Will Schott called The Linux Command Line. It seemed easy enough for me to understand and I meant to come back to it later. Now I can't find any mention of it!
I've only got Mint on my computer so I must have seen the book using our OS.. Googling the title and author produces no mention of the book and it's not on Amazon either.
I feel stupid having to ask for help over something my own fault but step in if you can, please.
