=over =item glob EXPR =item glob Returns the value of EXPR with filename expansions such as the standard Unix shell F would do. This is the internal function implementing the C<< <*.c> >> operator, but you can use it directly. If EXPR is omitted, C<$_> is used. The C<< <*.c> >> operator is discussed in more detail in L. Beginning with v5.6.0, this operator is implemented using the standard C extension. See L for details. =back
