glob EXPR
    glob    Returns the value of EXPR with filename expansions such as the
            standard Unix shell /bin/csh would do. This is the internal
            function implementing the "<*.c>" operator, but you can use it
            directly. If EXPR is omitted, "$_" is used. The "<*.c>" operator
            is discussed in more detail in the section on "I/O Operators" in
            the perlop manpage.
