Which is why MadeInGermany added the /. in the suggestion:
Code:
test -d "$dir"/.

If the caller doesn't have search permission in $dir, pathname resolution for "$dir"/. will fail, so test -d "$dir"/., chdir($dir), chdir($dir/.), and stat($dir/.) will all fail.

Yeah. I overlooked the /. when I responded to the post.

Also, I don't think your response to my post was up when I went to edit/delete. Since there's a response to it, perhaps you should undelete it (if possible).
