PERL TRAINING IN CHENNAI

Perl training in chennai strongly determined to provide Realtime and Practical Trainings on Perl Scripting. We have been providing Perl Scripting Language Training for Automating Test Scripts for more than FIVE years. All our sessions are completely practical and interactive paired with Realtime Methodologies, Project Scenarios and Interview Guidance exclusively on Unix and PERL

About PERL Course

Perl is a scripting language which allows for rapid prototyping of projects formerly done with a programming language or a shell. It incorporates all the functionality of C (including a UNIX system interface), the Shells, grep, sed, and awk. The topics in the course will aid all computer users - from end user to programmer to administrator alike.

PERL Training Course Contents

PERL course content is exclusively designed with Basics through Advanced Concepts.
This course teaches both the programming interface and the techniques that can be used to write procedures in PERL (Practical Extraction and Report Language). PERL is now available for all system platforms, but is usually not provided by the system's manufacturer. Each student will be able to use PERL techniques and commands to write scripts to perform various user and administrative tasks.

This course teaches advanced concepts and capabilities that can be used to write procedures in PERL (V5), especially the new interfaces that use object-oriented features. Each student will be able to use PERL techniques and commands to write scripts to perform various user and administrative tasks, implementing advanced features of the language.

Version

SUN Solaris (V7-V10), IBM AIX V4.3, 5L (V5.1 and V5.2), HP-UX (V11 and V11i), and SGI IRIX V6.5, Linux (Red Hat * SuSe)

Exercises

There are several hands-on machine exercises. All five Unix platforms will be available for lab exercises.
