Hello fellow instructors!
I don't know if anyone of you folks are reviewing the Linux+ Official Material (Instructor Guide / Practice Labs / Videos) and so on, but I'd like to contribute with it.
Well, I started to analyzing the content by executing some practice labs, as well as, reading carefully the Instructor Guide, seeking for typos, broken links, and other related mistakes that might be there and cause some confusing to our students during the classes. I found out some, and I'd like to share with you in order to discuss the subject, and to know whether some of you agree or disagree about such points raised here.
The first one is about "Command Subcommand Option Argument". The practice question addressing this subject brings the use of "Subcommand", of the ip command, and asks to point out what option would be the correct one related to the specified port. The correct answer should be the "Command Argument" one, rather than the "Subcommand".
ip addr show eth0
ip -> the command
addr -> the subcommand (here we could use others like link, route...)
show -> the option (here we could use add, del...)
eth0 -> the argument (you can use another interface as an argument. The argument is the part of the command line that specifies the target that the command should operate on)
In this case the port (interface), should be classified and an argument.
The attachment file named "Practice-Question-Subcommand.png" shows the option "Argument" as a mistake.
The second one is about "displaying contents of a file". Among the options displayed, only two should be used to do that: cat and less. However, the answer is classified as wrong.
One of the those which would be classified as a correct one for this question was the touch command.
The attachment file named "Practice-Question-Display Contents of a File.png" shows the option with the command "cat" as a mistake.
