1.1 What Should You Know Already?

We'll presume that you've already
read Learning Perl, or at least pretend you
have, and that you've played enough with Perl to
already have those basics down. For example, you
won't see an explanation in this book that shows how
to access the elements of an array or return a value from a
subroutine.

Make sure you know the following things:

How to run a Perl program on your system

Scalars

Arrays

Hashes

Control structures such as while,
if, for, and
foreach

Subroutines

Perl operators such as grep,
map, sort, and
print

File manipulation such as open, file reading, and
-x (file tests)

You might pick up deeper insight into these topics in this book, but
we're going to presume you know the basics.
