How can I get all the things (files, subdirs etc) in a directory and I want to make it platform independent? Will this code work on every operating system? 
glob "* .*"

[download]
(There is a space after the first *) If I recall there was some issue with this a few years ago on Windows and since then I keep using opendir and readdir for this specific case: 
opendir my $dh, $dir or die;
my @things = readdir $dh;

[download]
but now I tried it again and it seems to work on both Linux and Windows.

So what is the recommended way to list all entries in a directory?

Update

Apparently it was not clear from my question but I am only interested in the top most directory.

Regarding platform independence: yeah, I could have pointed out that I mentioned Linux and Windows as those are the two where I tried and no, I don't want to solve this perl question for operating systems that do not have perl.
