Ever wondered how the search or replace button works? They are very useful commands. 

For beginners and professionals alike, we use these commands in our day-to-day work life, at least once a day. This is why I felt the need to build a course that could help you increase your knowledge and save time while working with strings or any sort of text.

The objective of this course is to help you get a strong grip on regular expressions, or in shorthand, regex. Instead of writing repetitive tasks, it mainly focuses on efficient searching in text files.
