Dear Users of this Board!

i would like to thank all the good and knowledgeable experts - you - for your ongoing support. You have helped countless people with your expertise and the willingness to share it.

Still, we have some rules in place and one of them is that homework and coursework is allowed only in the specialized board for this kind of questions. It is sometimes obvious if a question is homework/coursework and sometimes - like in this thread here - it is not.

In such a case we have established a simple course of action: someone, usually a moderator, asks what the thread opener has tried so far. If he answers this and shows his effort we at least have the proof that he did try to work out a solution, however inapt. We will try to correct what he did wrong, explian which misconceptions have led him astray, and so on.

Experience shows that the lazy (instead of inapt/uneducated) people, regardless of being student or not, will not answer such a question but istead wait to be spoon-fed a complete solution. As we - and i think we all can agree on this - do not want to support utter lazyness with our work we ask you to simply refrain from answering questions where a moderator or other user has asked such a question.

Please treat "What have you tried?" as a STOP-signal as long as the question is not answered by the thread owner!

Thank you for your consideration.

PS: @protocomm: I have hidden your answer for exactly this reason. Not, because it was wrong, but because it was premature. Thanks for understanding.

@balajesuri: Special thanks for holding up this rule.

quiz

QUIZ(6) 							 BSD Games Manual							   QUIZ(6)

NAME

     quiz -- random knowledge tests

SYNOPSIS

     quiz [-t] [-i file] [question answer]

DESCRIPTION

     The quiz utility tests your knowledge of random facts.  It has a database of subjects from which you can choose.  With no arguments, quiz
     displays the list of available subjects.

     The options are as follows:

     -t      Use tutorial mode, in which questions are repeated later if you didn't get them right the first time, and new questions are presented
	     less frequently to help you learn the older ones.

     -i      Specify an alternative index file.

     Subjects are divided into categories.  You can pick any two categories from the same subject.  quiz will ask questions from the first cate-
     gory and it expects answers from the second category.  For example, the command ``quiz victim killer'' asks questions which are the names of
     victims, and expects you to answer with the cause of their untimely demise, whereas the command ``quiz killer victim'' works the other way
     around.

     If you get the answer wrong, quiz lets you try again.  To see the right answer, enter a blank line.

   Index and Data File Syntax
     The index and data files have a similar syntax.  Lines in them consist of several categories separated by colons.	The categories are regular
     expressions formed using the following meta-characters:

	   pat|pat  alternative patterns
	   {pat}    optional pattern
	   [pat]    delimiters, as in pat[pat|pat]pat

     In an index file, each line represents a subject.	The first category in each subject is the pathname of the data file for the subject.  The
     remaining categories are regular expressions for the titles of each category in the subject.

     In data files, each line represents a question/answer set.  Each category is the information for the question/answer for that category.

     The backslash character (``'') is used to quote syntactically significant characters, or at the end of a line to signify that a continuation
     line follows.

     If either a question or its answer is empty, quiz will refrain from asking it.

FILES

     /usr/share/games/quiz  The default index and data files.

BUGS

     quiz is pretty cynical about certain subjects.
