Recomend any good books

I’m looking for any books that will help me understand commands used in Terminal, would this be of any use?

That’s 2009 … so dont expect it to be current.

That said, the command line stuff should mostly be relevant.

I did a search on words ‘ubuntu’ and ‘terminal’
that book was the first one…
most of the rest were older even, some results were even hardware :o

Try a search on “unix shell” or “bash” (bourne again shell)
