Course overview
This course contains topics about Regular Expressions (aka. REGEX or REGEXP). Using regular expression, you will be able to extract the most relevant pieces of information from any text-based source such as show commands results in IOS CLI commands.
Very sophisticated forms of REGEX patterns are used in programming and automation tools. However, my focus in this course will be those patterns that suit network engineers most.
