Perl Programming

|
Course Description:
Perl retains its prominence in the development world because
it combines some of the best elements of existing programming
languages like C and C++, scripting languages like awk and
sed, and shell languages like Unix ksh.
The greatest strengths of the Perl language are its text
processing features, its data manipulation abilities and
the ease with which it can interact with operating systems
and database systems and the ability to create CGI programs
for use with web applications.
This Perl course will combine lecture with hands-on programming
to help you become an effective Perl programmer in a short
time. This class will cover the new features introduced
with the latest release of Perl (Version 5) including modules
and object oriented programming. This course will make you
productive quickly, pointing out the essential elements
of the language.
