With the ever increasing shift away from GUI tools in favor of automation, the need for learning Regular Expression is also increasing. As system administrators, engineers, and developers implement automation across applications and enterprises. The need to validate, extract, match, and capture values from within data sets is becoming more and more important as well. Regular expression is available in almost every programming language. No matter what your background is and if you deal with data of any kind, Regular Expression will make you more productive and efficient with the data you manage. This course, Introduction to Regular Expression (Regex), is for those who seek a better understanding of their data and how to become more productive with that data. First, you'll learn to use shorthand metacharacters. Next you'll learn all about anchors and word boundaries. Finally, you'll explore lookarounds. By the end of the course, you'll have the knowledge required to both read regular expressions you find online, as well as how to craft elegant expressions of your own.

Hello everyone, my name is Josh Duffney and welcome to my course Introduction to Regular Expression.

I am a DevOps Engineer at a software company called Paylocity. Most people consider regular expression to be some form of magic that they can use, but don’t understand. This course demystifies the notion of magic around regular expression by teaching you how to use metacharacters and metasequences in regular expression to craft meaningful expressions.

In this course you’ll learn to use shorthand metacharacters, anchors, word boundaries, lookarounds and much much more.

By the end of the course you’ll have the knowledge required to both read regular expressions you find online as well as how to craft elegant expressions of your own.

I hope you’ll take this opportunity to stretch yourself a little and join me on this journey to learn regular expression. Who knows, maybe you’ll even become a wizard of regex!
