Match Patterns ("*")

• The symbol "*" is a multiplier that indicates match zero or more instances of the previous item .
• Example:
  

  $theVar = "This is a test.  Beeeeeeeeeeeeeeep";
  if ($theVar =~ /be*p/) {
      (print "Match One\n");  # Would Not Match
  }
  if ($theVar =~ /Be*p/) {
      (print "Match Two\n");  # Would Match
  }
  if ($theVar =~ /t*e*p/) {
      (print "Match Three\n");  # Would Match
  }
  if ($theVar =~ /[tT]*his/) {
      (print "Match Three\n");  # Would Match
  }
