Actually, no--the filename isn't supplied as the argument
to your subroutine. There aren't any arguments, in fact.
(Actually, if you peek at @_ in your wanted function, you
*will* see arguments. But they're not actually supplied
as arguments to your subroutine: they're the arguments to
File::Find's finddir subroutine, which calls your wanted
sub as &$wanted, which makes its @_ visible to your
subroutine.) More in
perlsub.
But that's getting off track. Anyway, what File::Find
does is sets some package variables and
$_ to the file name, the directory, and a combination
of those two. From the docs:
$File::Find::dir contains the current
directory name, and $_ the current filename within
that directory. $File::Find::name contains
"$File::Find::dir/$_". You are chdir()'d to
$File::Find::dir when the function is called.
The function may set $File::Find::prune to prune
the tree.
