Question 13.2


Hello everybody, sorry to bother you but I'mm a bit puzzled about the correctness of the answers for the Question 13.2.
I mean the question is:
"Which commands get a list of all man pages that have file in their names? Select all answers that apply."
How could it be that the correct answers are A and B:
A. $ what is file
B. $ whatis file
While from what I've read in the chapter it seems to me at least that correct answers should be C and D:
C. $ apropos file
D. $ man -k file
I google it and here https://superuser.com/questions/207450/list-of-all-available-man-pages it seems to support my idea ...

Can you clarify it to me so to help me understand ...

Thank you and once again sorry to bother you ...

    "that have file in their names" . FOr this the correct answer should be "whatis file" and "man -f file" (whatis is just an alias for man -f) "man -k file" (and its alias "apropos file") give you all pages that have "file" in their description, not their name, and it is a much longer list. "what is file" is indeed just an error

    The quiz should be corrected to accept only "whatis file". Thanks :)
