Frequently Asked Questions
Regular Expressions is a very powerful tool for processing text files and searching and modifying text strings. Several dozen lines of programming code can be easily replaced by one line of regex.
A regular expression, or Regex, is a string of characters used to create search patterns. If a string contains the designated search pattern, it can be verified using Regex.
With the exception of repeating the previous expression at least once, this operator is similar to the match-zero-or-more operator; for more information on what it operates on, how some syntax bits affect it, and how the expression backtracks to match it, check the above tool.
*$ stands for – match any character that appears zero or more times from start to finish. That basically means matching every character in the string from the beginning to the end. There’s not much use for this pattern.
