Just like you I was also a computing student and you won't really learn
anything if you don't exert any effort in working out these problems. I
did a similar UNIX subject and most people who failed in class did well
in assignments but bombed final exams because they had other people do
assignments for them. Therefore it might help if you at least posted
what you have done so far and what's getting you stuck. From your post
it seems you have done absolutely *nothing*, not even try. Questions
like what does "cat 1> m1" do takes like less than 2 mins to solve even
for someone who have never used cat before (hint: man cat).
