Today, I discovered #bash and #ksh extglobs. Very powerful, almost as good as regex!

From BASH(1):

If the extglob shell option is enabled using the shopt builtin, the
shell recognizes several extended pattern matching operators.  In the
following description, a pattern-list is a list of one or more patterns
separated by a |.  Composite patterns may be formed using one or more
of the following sub-patterns:

    ?(pattern-list)
         Matches zero or one occurrence of the given patterns.
    *(pattern-list)
         Matches zero or more occurrences of the given patterns.
    +(pattern-list)
         Matches one or more occurrences of the given patterns.
    @(pattern-list)
         Matches one of the given patterns.
    !(pattern-list)
         Matches anything except one of the given patterns.
