     There are two different sets of meta-characters: those  that
     are  recognized anywhere in the pattern except within square
     brackets, and those that are recognized in square  brackets.
     Outside square brackets, the meta-characters are as follows:

       \      general escape character with several uses
       ^      assert start of  subject  (or  line,  in  multiline
     mode)
       $      assert end of subject (or line, in multiline mode)
       .      match any character except newline (by default)
       [      start character class definition
       |      start of alternative branch
       (      start subpattern
       )      end subpattern
       ?      extends the meaning of (
              also 0 or 1 quantifier
              also quantifier minimizer
       *      0 or more quantifier
       +      1 or more quantifier
       {      start min/max quantifier

     Part of a pattern that is in square  brackets  is  called  a
     "character  class".  In  a  character  class  the only meta-
     characters are:

       \      general escape character
       ^      negate the class, but only if the first character
       -      indicates character range
       ]      terminates the character class
