Mastering Regular Expression (RegEx) Usage in PERL: A Comprehensive Guide

In this engaging episode, we delve into a wide range of captivating topics designed to enhance your understanding of Regular Expressions (RegEx) in the context of PERL. We explore real-world applications of RegEx in VLSI through two illuminating examples, providing valuable insights into its practical usage. Additionally, we unravel the intricacies of string operations in PERL, offering in-depth explanations and practical demonstrations. The episode also serves as an introduction to Regular Expressions, acquainting you with the fundamental concepts and principles. We shed light on the crucial role of meta-characters and meta-symbols in RegEx, elucidating their significance and usage. Furthermore, we dive into pattern matching techniques utilizing RegEx in PERL, accompanied by five illustrative examples that showcase its practical implementation. Along the way, we explore non-default delimiters, examine matched groups and their extraction, and demonstrate their application through a detailed example. Finally, we explore the powerful capabilities of the split function in conjunction with RegEx in PERL, as well as the similarities between PERL and SED in terms of search and replace functionality.

It was great... u just made it easy fr us 2 understand by explaining hw all these things comes into use in vlsi industry

[amitthakur]

@TechSimplified Tv can you explain 43:07 example what is happening

[jaljoshi]

It would be great if you create a separate episode for Perl VLSI interview questions!!

[jaljoshi]

You explained every slide in a great details, thanks.

[nainas]

Sir.. ur videos are worth to watch.. thanku..

Sir, I have a doubt. In the example for extracting match group at 43:07, why does $1 contain string upto 'h'? Shouldn't it go upto 'c' for 'cat' because it has first 'at' characters? I have run this code still I am not able to get the logic. Please help. Thank You!
