Perl Programming/Keywords/glob
The glob keyword
glob returns in list context a (probably empty) list of filename extensions on the value of EXPRESSION. Called in scalar context, it iterates through such filename expansions and returns undef when the list is exhausted. If EXPRESSION is omitted, $_ is used instead.
glob splits its arguments on whitespace and treats each segment as a separate pattern.
Syntax
