Perl is a programming language which can be used for a
large variety of tasks. A typical simple use of Perl would
be for extracting information from a text file and
printing out a report or for converting a text file into
another form. But Perl provides a large number of tools
for quite complicated problems, including systems
programming.
Programs written in Perl are called Perl scripts, whereas
the term the perl program refers to the system program
named perl for executing Perl scripts. (What, confused
already?)
If you have used shell scripts or awk or sed or similar
(Unix) utilities for various purposes, you will find that
you can normally use Perl for those and many other
purposes, and the code tends to be more compact. And if
you haven't used such utilities but have started thinking
you might have need for them, then perhaps what you really
need to learn is Perl instead of all kinds of futilities.
Perl is implemented as an interpreted (not compiled)
language. Thus, the execution of a Perl script tends to
use more CPU time than a corresponding C program, for
instance. On the other hand, computers tend to get faster
and faster, and writing something in Perl instead of C
tends to save your time.
