glob EXPR

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 "I/O Operators" in perlop.

Beginning with v5.6.0, this operator is implemented using the standard File::Glob extension. See File::Glob for details.
