38.Sh NAME
39.Nm quiz
40.Nd random knowledge tests
41.Sh SYNOPSIS
42.Nm
43.Op Fl t
44.Op Fl i Ar file
45.Op Ar question answer
46.Sh DESCRIPTION
47The
48.Nm
49utility tests your knowledge of random facts.
50It has a database of subjects from which you can choose.
51With no arguments,
52.Nm
53displays the list of available subjects.
54.Pp
55The options are as follows:
56.Bl -tag -width indent
57.It Fl t
58Use tutorial mode, in which questions are repeated later if you didn't get
59them right the first time, and new questions are presented less frequently
60to help you learn the older ones.
61.It Fl i
62Specify an alternate index file.
63.El
64.Pp
65Subjects are divided into categories.
66You can pick any two categories from the same subject.
67.Nm Quiz
68will ask questions from the first category and it expects answers from
69the second category.
70For example, the command ``quiz victim killer'' asks questions which are
71the names of victims, and expects you to answer with the cause of their
72untimely demise, whereas the command ``quiz killer victim'' works the
73other way around.
74.Pp
75If you get the answer wrong,
76.Nm
77lets you try again.
78To see the right answer, enter a blank line.
79.Sh "Index and Data File Syntax"
80The index and data files have a similar syntax.
81Lines in them consist of several categories separated by colons.
82The categories are regular expressions formed using the following
83meta-characters:
84.Pp
85.Bl -tag -width "pat|pat" -compact -offset indent
86.It pat|pat
87alternate patterns
88.It {pat}
89optional pattern
90.It [pat]
91delimiters, as in pat[pat|pat]pat
92.El
93.Pp
94In an index file, each line represents a subject.
95The first category in each subject is the pathname of the data file for
96the subject.
97The remaining categories are regular expressions for the titles of each
98category in the subject.
99.Pp
100In data files, each line represents a question/answer set.
101Each category is the information for the question/answer for that category.
102.Pp
103The backslash character (``\e'') is used to quote syntactically significant
104characters, or at the end of a line to signify that a continuation line
105follows.
106.Pp
107If either a question or its answer is empty,
108.Nm
109will refrain from asking it.
110.Sh FILES
111.Bl -tag -width /usr/share/games/quiz.db -compact
112.It Pa /usr/share/games/quiz.db
113The default index and data files.
114.El
115.Sh BUGS
116.Nm Quiz
117is pretty cynical about certain subjects.
