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.
