Not the worst bash/shell tutorial I've read. This is the most polite thing I can say about it.
If by briefly you mean inaccurately and with bad examples, then you're right.
I don't recommend this tutorial, unless one wants to see some (most of the?) common errors that Bash programmers make.
Agreed, but it was just something I encountered while a-googling, and thought "I know where I should post this". I didn't actually proof-read it (in fact it seems that you spent more time on it than I did). Happy bash-ing!
