This book shows you how to write regular expressions through examples. Its goal is to
make learning regular expressions as easy as possible. In fact, this book demonstrates
nearly every concept it presents by way of example so you can easily imitate and try
Regular expressions help you find patterns in text strings. More precisely, they are
specially encoded text strings that match patterns in sets of strings, most often strings
that are found in documents or files.
Regular expressions began to emerge when mathematician Stephen Kleene wrote his
book Introduction to Metamathematics (New York, Van Nostrand), first published in
1952, though the concepts had been around since the early 1940s. They became more
widely available to computer scientists with the advent of the Unix operating system—
the work of Brian Kernighan, Dennis Ritchie, Ken Thompson, and others at AT&T Bell
Labs—and its utilities, such as sed and grep, in the early 1970s.
