matches position just before the first character of the string   matches position just after the last character of the string   matches a single character  Does not matter what character it is  except newline   matches preceding match zero or more times   So       means - match  from beginning to end  any character that appears zero or more times  Basically  that means - match everything from start to end of the string  This regex pattern is not very useful   Let s take a regex pattern that may be a bit useful  Let s say I have two strings The bat of Matt Jones and Matthew s last name is Jones  The pattern  Matt  Jones  will match Matthew s last name is Jones  Why  The pattern says - the string should start with Matt and end with Jones and there can be zero or more characters  any characters  in between them   Feel free to use an online tool like https   regex101 com  to test out regex patterns and strings
