Do you understand the most powerful tool for text searching and manipulation? Can you search and find a single entry amongst thousands with only a rough idea of what is? Do you want to learn? Originally conceived in the 1950’s Regular Expressions are still commonly used today to search and validate text. And virtually every modern framework has a Regular Expression engine. For simple queries and validators, it is easy enough to copy pre-made scripts, but they will do little to help with searching for entries in custom logs or general text. Understanding the language and its use unlocks a world of possibilities.
