.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm quiz
|
||
|
|
utility tests your knowledge of random facts.
|
||
|
|
It has a database of subjects from which you can choose.
|
||
|
|
With no arguments,
|
||
|
|
.Nm quiz
|
||
|
|
displays the list of available subjects.
|
||
|
|
.Pp
|
||
|
|
The options are as follows:
|
||
|
|
.Bl -tag -width indent
|
||
|
|
.It Fl 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.
|
||
|
|
.It Fl i
|
||
|
|
Specify an alternate index file.
|
||
|
|
.El
|
||
|
|
.Pp
|
||
|
|
Subjects are divided into categories.
|
||
|
|
You can pick any two categories from the same subject.
|
||
|
|
.Nm Quiz
|
||
|
|
will ask questions from the first category 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.
|
||
|
|
.Pp
|
||
|
|
If you get the answer wrong,
|
||
|
|
.Nm quiz
|
||
|
|
lets you try again.
|
||
|
|
To see the right answer, enter a blank line.
|
||
|
|
.Sh "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:
|
||
|
|
.sp
|
||
|
|
.Bl -tag -width "pat|pat" -compact -offset indent
|
||
|
|
.It pat|pat
|
||
|
|
alternate patterns
|
||
|
|
.It {pat}
|
||
|
|
optional pattern
|
||
|
|
.It [pat]
|
||
|
|
delimiters, as in pat[pat|pat]pat
|
||
|
|
.El
|
||
|
|
.Pp
|
||
|
|
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.
|
||
|
|
.Pp
|
||
|
|
In data files, each line represents a question/answer set.
|
||
|
|
Each category is the information for the question/answer for that category.
|
||
|
|
.Pp
|
||
|
|
The backslash character (``\e'') is used to quote syntactically significant
|
||
|
|
characters, or at the end of a line to signify that a continuation line
|
||
|
|
follows.
|
||
|
|
.Pp
|
||
|
|
If either a question or its answer is empty,
|
||
|
|
.Nm quiz
|
||
|
|
will refrain from asking it.
|
||
|
|
.Sh FILES
