glob

glob EXPR

This function returns the value of EXPR with filename expansions such as a shell would do. (If EXPR is omitted, $_ is globbed instead.) This is the internal function implementing the <*> operator, except that it may be easier to type this way. For example, compare these two:

@result = map {
 glob($_)
}
"*.c", "*.c,v"; @result = map <${_}>, "*.c", "*.c,v";

The glob function is not related to the Perl notion of typeglobs, other than that they both use a * to represent multiple items.
