no it does not close the old directory handle unless you use the same name.

I believe that opening a new directory closes the old
directory handle, just like opening a new file closes
the old file handle, that used to be on that handle name.
The important thing is to read all the entries from
the directory before recursing, because as soon as you
recurse, the directory handle will get replaced with
the one from the inner direrctory. So the Con
my @entries = readdir DIR
is the important part. It has to be my, not our, otherwise
the deeper instances won't get their own.
adding closedirs makes it clearer, but shouldn't be required, and
yes the closedir belongs BEFORE the recursion, otherwise we'd
be closing a closed dirhandle many times on the way out. There's
only! one dirhandle in the code under discussion.
Good morning!
