In short, "alnum" matches any letter (ALphabetic character) or digit (NUMeric
character);  the dollar sign matches the "null string at the end of a line"
(in other words, there are to be no other characters beyond this point in
order for the pattern to match).

See IEEE POSIX 1003.2 or any decent "extended regular expressions" reference.
