If you had perl installed, then you already had that, as perl ships
and installs that document, along with a boatload of other docs.

>hi monks,

What does religious asceticism have to do with Perl?

See the first page or so of perldoc perldata. It is a rather terse but
well-written introduction into that subject matter.

>when should i use $ and @ as prefix.

Use $ whenever you are talking about a single value aka scalar. Use @ when
you are talking about a collection of values which is indexed by consecutive
natural numbers.

>an example may be a little useful :)

perldoc perldata has numerous examples.
