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.
